that's even worse when the developer gets used to the simpler, -- Why can clocks not be compared unless they are meeting? However, there are tools for such analyses: Linters like FindBugs or Sonar. There's nothing toString can do to address this plausibly, but the point is: This. rev2023.7.3.43523. Properties are included in toString method. basically free, and they are swamped with work. These methods will extend the type of the first parameter, as if they were instance methods, using the @ExtensionMethod feature.. For example, if you create public static String toTitleCase(String in) { . Currently this is vaguely possible by overriding the default toString, but requires manually writing the toString method, which is especially non-trivial if . Have a question about this project? What about an AtomicReference object that is referencing null? Properties are included in toString method. (We could save one allocation if we implemented Iterator in the same type, which anonymous classes don't support, though we could define a class at the end of the file.) The entity has a bidirectional relationship with another entity, so I want to exclude this entity from the toString method. In the final act, how to drop clues without causing players to feel "cheated" they didn't find them sooner? What I'd like to see, which I think is possible, is something like this: Maybe even the same functionality on a ToString.Include where I can specify that, in User for instance, I only want the field named permissionName. The conclusion is that the feature should not be added. If you need to set non-default values for any of these parameters, just add those annotations explicitly; @Data is smart enough to defer to those annotations. We'll just toss that exception right on through, but we will add: Hey, maybe you should consider excluding a field maybe. The text was updated successfully, but these errors were encountered: Any reason why the contents of the mask needs to be configurable? There's also the issue of choosing between a field and getter method, but I believe this can be easily solved using reflection during preprocessing. Why would you include such a field in the tostring at all? You switched accounts on another tab or window. It should be possible to write a rule for this type of bug, and such a rule would also find similar non-lombok bugs. Specifically, there would be at least two separate use-cases; using a field name in a POJO reference, and using a field name within a Collection (List). #jpa #hibernate #eclipselink #intellijidea #java #kotlin #jpabuddy #lombokBy default, Lombok @ToString implementation prints the class name and all the field. 1. So just a shortcut for @ToString.Exclude on the field and @ToString.Include on a method that calls, let's say, value.getId()? @Value class Sensitive { T value; String toString() { return "***"; } }), but this can be cumbersome. @adrianfilipescu yes you're right it support VScode, Lombok doesn't work with spring-boot-maven. @ToString.Mask("(?=. Does the EMF of a battery change with time? Is the executive branch obligated to enforce the Supreme Court's decision on affirmative action? Why don't Java's +=, -=, *=, /= compound assignment operators require casting long to int? Already on GitHub? @ToString(exclude) option is not working as expected #1373 - GitHub @Builders always get an automatic toString. yourself. When it comes to documentation, I believe that it's not Why Is PNG file with Drop Shadow in Flutter Web App Grainy? Bad news; I am rescinding my earlier promise to accept a PR, and closing the issue. By clicking Sign up for GitHub, you agree to our terms of service and The text was updated successfully, but these errors were encountered: Do you really mean @ToString.Include(onlyFields = "id") 5% definitely isn't enough, so this leads to the conclusion that the feature should not be added. I've been thinking more about this issue, and it certainly is a challenge to introduce a universal solution without making the project depend on new external classes (in order to support delombok). Otherwise this will probably always require additional specialized tests for all entities (possibly iterating over their package and using reflection to test all combinations), and every single developer on the team will always need to be taught this special exception and remember to explicitly check for it during all code reviews. It also implies this should be explicitly documented as a common issue (or better, as a prerequisite) in the ToString documentation, Yes, that would help, although I guess not too much. How would lombok possibly know? Non-Arrhenius temperature dependence of bimolecular reaction rates at very high temperatures. Lombok @ToString basic example The Lombok @ToString annotation generates an implementation for the toString method and by default, it'll print your class name, along with each field, in order, separated by commas. If a getter exists for a field to be included, it is called instead of using a direct field reference. All static fields will be skipped entirely (not considered for any of the generated methods, and no setter/getter will be made for them). As it is, I just never use Lombok's toString() except for the most basic program, If it would be feasible I'd prefer a generic config like. Closed . I'll note for a reference that there's also an option of generating some kind of toStringOnlyFields1() on a target class, which would make the alternative possible, also making the code a bit cleaner. @ToString(doNotUseGetters = true). This would give maximum customisation while keeping lombok's effort and maintenance burden at a minimum. This is insane - toString. This behaviour can be suppressed: Specifically, there would be at least two separate use-cases; using a field name in a POJO reference, and using a field name within a Collection (List). }, you can use the @ExtensionMethod feature to make it look like the java . Some want to know if something is valid or not. There is no point adding @ToString.Exclude and then @ToString.Include in the code for each field. The text was updated successfully, but these errors were encountered: Why is @ToString.Exclude not sufficient in this case? (this tutorial example (scroll to: Bidirectional @OneToMany chapter) is absolutely valid enough ) the matter. excerpting (first sentence, couple items from a list). However, this behaviour is no different from e.g. I'm not sure I understand what you're proposing. String accountId; So account id 1234567890 will be printed as ******7890 in toString method. : If that's not good enough, and you definitely want to have the field in there with some special rendering, the annotated method is warranted. Cch s dng annotation @ToString ca lombok - Deft Blog I can imagine this causing serious issues in a production application if the stack is just allowed to overflow, and I'm handling thousands of requests per minute. It is important to note that this annotation only works when there is also a @Builder or a @SuperBuilder annotation present. Obviously, I would prefer for the project maintainers to spend They just crowd out the useful debate. Different results fetching results with query api vs. hql. Well occasionally send you account related emails. In order to reduce the boilerplate when constructing objects for classes with generics, you can use the staticConstructor parameter to generate a private constructor, as well as a static method that returns a new instance. Cannot evaluate .toString(), Would be nice if this can be also solved in the same way as JSON annotations, Describe the target audience ;) How to resolve the ambiguity in the Boy or Girl paradox? When working with JPA and Lombok, remember these rules: easily jump in to fill this gap without needing much in the way of Since version 16.16 I have problems with @tostring(exclude = "myProperty1, myProperty2") example. On Fri, Apr 10, 2020 at 2:27 PM scscgit ***@***. Is @NonNull annotation of Lombok allows the default constructor to give null values? Having both @ToString.Exclude and @ToString.Include on a member generates a warning; the member will be excluded in this case. Even if they agree this is extremely unlikely to be an issue, they want to be able to say in their docs that 'nothing about your password is logged, at all, anywhere'). Have a question about this project? Lomboked version, The annotation would be nested in ToString annotation and could look like. You will have to update the lombok installed in your eclipse (download the new lombok.jar, run java -jar lombok.jar and restart Eclipse). All that pain and crappy implementation, and for what? For example, if a field is annotated with some JPA 'this is a backref' annotation, we can see that, and skip it. Not the answer you're looking for? it just doesn't work that way. Not working on a PR, don't worry ;-) So please don't make them. ***> wrote: @Bryksin Is there something what can't be achieved easily using @ToString.Include and how should the output look like? Shoving FQN classnames in a string literal is vetoed. Without lombok, you let your IDE generate the thing, and manually go in and replace the lines for the 2 masking fields with stars or whatnot. You'd think that the argument here is 'this makes it possible to adhere to regulations and hide sensitive information from logs', but that is NOT correct. For example, you want to hide the birthdate due to regulation requirements, but your entire system uses. You switched accounts on another tab or window. Because lombok can already do that for you; you can either go with: The exclude variant isn't even boilerplate; if that's what you want, it is 100% as good as the mask proposal (in that you need to put an explicit annotation on the field). The simplest solutions to translate objects within Collections or Arrays would require either Streams, turning Java 8 into dependency, or some libraries with a similar functionality. For example, a field of type, Some want to compare the value to some known SENTINEL value, printing whether it is sentinel or not. ToString ; @Data public class MyClass { public static void main ( String args []) { MyClass myClass = new MyClass (); System. to your account, Describe the feature You signed in with another tab or window. You won't have to answer the incoming pile of bug reports and feature requests. Making statements based on opinion; back them up with references or personal experience. I would be happy to implement it when I have the time, but would be pleased if someone beat me to it! Well occasionally send you account related emails. I will lay out the reasons for it; this way, if you feel this decision is in error, please delve into the arguments laid out here; show how they are either incorrect or insufficient. Developers use AI tools, they just dont trust them (Ep. which could be possibly also related to this, as Lombok also doesn't document them. And the @ToString.Include alternative solves all 3 of these major issues: You need not mess with anything tostring related when adding or removing or changing non-mask fields, it is easy to see that masking of these sensitive fields is being done, and it's unlikely you'll remove one of these masker methods by accident (the most likely route to an accident is that you rename that field, resulting in the masking method no longer hiding it, as it no longer shares the name now. (either) not use it This annotation will be really helpful to avoid printing PII information in logs. I have no problem sending a PR that adds a JavaDoc if you think that is the most important problem here. ), is a significant advantage of the @ToString.Include solution. Solution 1 Works for me. how to give credit for a picture I modified from a scientific article? You can include them by specifying an explicit annotation (@Getter or @ToString, for example) and using the 'of' parameter. That's causing the stack-overflow error. Already on GitHub? For logs, make it disappear entirely. Some want the data to be analysed for sensitive information, and if it is there, to print it, whereas if it is not, leave it as normal. so while fetching the table data you want, the other tables joined are also fetched. if a logger causes a business logic method to fail. If there are any issues with my example other than the effort needed to write the abstract syntax tree algorithm, then I'm looking forward to receiving a feedback. How to take large amounts of money away from the party without causing player resentment? By setting callSuper to true, you can include the output of the superclass implementation of toString to the output. Lombok and JPA: What Could Go Wrong? - DZone Aren't you contradicting yourself there a little bit? Some want the choice of what to print to depend on the dynamic type of the field. below part is optional Not a bunch of stars, as that wrongly suggests the string is at least that long. Is Linux swap still needed with Ubuntu 22.04. [FEATURE] apply @ToString.Exclude to @Builder toString #2891 - GitHub Is that set or unset? where talk is cheap but code is gold. For an automatic compile-time solution, yes. Who reads the docs? You signed in with another tab or window. I leave the question of choosing name open. A lot worse. I've reviewed this one, really tried to get to the heart of the cost/benefit here. What is the best way to visualise such data? By clicking Post Your Answer, you agree to our terms of service and acknowledge that you have read and understand our privacy policy and code of conduct. By default non-static fields are excluded in generated toString (). The benefit is now pushed up from 80% to 95%, but the costs are also MUCH larger: Far more dev time, far more maintenance burden, and a continuous effort to keep it up to date with well known types and particular masking behaviors. I doubt that a runtime-optimized Jackson serialization is much slower than a native implementation. ), There are also other similar JPA-related issues with @EqualsAndHashCode, e.g. Moreover, JSON lacks the information about the class, which is sometimes important for debugging. Why extracted minimum phase component have inverted phase? There's also one specific suggestion I'll make: instead of forcing us to Exclude a field and Include a method that prints the field, would it be feasible to support something like ToString.Of for a field level? Does "discord" mean disagreement as the name of an application for online conversation? This isn't legal java and makes no sense to me. It means it's hard to see that these fields are even being masked. privacy statement. Sign in Join For Free Lombok is a great tool that makes your Java code. By using this attribute, we can list the field names that we want to exclude from the generation of toString: By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. if a logger causes a business logic method to fail. 0.01% at best? I also vote for this feature to avoid printing high critical PII to debug log. You switched accounts on another tab or window. You signed in with another tab or window. @Data is a convenient shortcut annotation that bundles the features of @ToString, @EqualsAndHashCode, @Getter / @Setter and @RequiredArgsConstructor together: In other words, @Data generates all the boilerplate that is normally associated with simple POJOs (Plain Old Java Objects) and beans: getters for all fields, setters for all non-final fiel. The obvious solution to me is to detect 'backlinkage', but without using resolution. I'm familiar with alternate approaches to excluding or including fields from a top level @ToString annotation. Well occasionally send you account related emails. Well occasionally send you account related emails. the same issues. ;) I don't see how the process of "learning what is the intention of an annotation" is in any way deterministic, and I believe such an important prerequisite should be very visible within the basic description, possibly even in annotation's JavaDocs, and not just in a "Small print" - where it's also missing. When did a PM last miss two, consecutive PMQs? This tradeoff is good for when speed is most important. Overview As we know, the toString () method is used to get the string representation of a Java object. To learn more, see our tips on writing great answers. Surely that is the case here: You're asking someone to hold their finger to the screen, and start going 'ooone, two, three.' - imagine it, have a cry, then join me in being amazed at how insane this practice is. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Why did CJ Roberts apply the Fourteenth Amendment to Harvard, a private school? This feature would allow to transform value for use in the toString generator. Extract value of element in XML with xmlstarlet. Analysis Like (13) Comment Save Tweet Share 35.55K Views Join the DZone community and get the full member experience. that I see. Arrays don't provide any way to wrap around the index accessor (to be called via deepToString()), so they are iterated using an index. How to get rid of the boundary at the regions merging in the plot? And Some want to leak length. What if we refactored masking methods into static methods in some other class? An outside person like you could @Data can handle generics parameters for fields just fine. It would be much more useful to see that the field is populated (and perhaps the length of string fields) than just leaving the fields out of the log message. match = boolean? Using a mask wouldn't add any value to the tostring. Connect and share knowledge within a single location that is structured and easy to search. Notifications Fork 2.2k; Star 12.1k. traversing even the path of collection-class-collection-field by choosing onlyFields = "employees.company.owners.id". @ToString takes an argument exclude, that can be used to exclude fields from to string. Also, there's a very interesting potential to create a solution even for extremely complex scenarios of nested objects, e.g. - jbx Sep 20, 2018 at 13:29 What do you mean with "when I select the window of my class". Have a question about this project? is not necessarily their expertise, and this is *exactly* the kind of thing Some want torender a subset of the information which can be provided without running afoul of regulations. I agree that Exclude, and Include on a method, are okay-ish workarounds. The Order entity class represents the order in an online store. mehdim2 129 9 It seems the hashCode of CartItem also tries to call into hashCode of ShoppingCart which causes the exact problem you describe, except with hashCode instead of toString. If it were possible to implement, I'd also suggest considering to add some static analysis, so that recursive ToString references are detected and the developer is notified, as it seems this may be a very serious issue in a production, e.g. Shall I mention I'm a heavy user of the product at the company I'm at applying at and making an income from it? where to add a very brief mention* of this issue, so I'm doing my best to It would be nice to have some out of the box configuration options for the ToString method in general. So ToString.Include(field = "permissionName"). Writing custom masking methods and annotating them with @ToString.Include might be tedious; also many of these methods will be exactly the same. I apologize for jumping the gun on promising we'd accept one. If you want to mask only concrete parts of a String, do it yourself (ie: in case needed for logs, apply mask on appender config). The fact that that the traffic on this issue seems to suggest that everyone thinks 'masking' means one thing, whereas it doesn't, also means there is a risk that lombok is making it way too easy to write code with security issues, because the users of this feature would misunderstand what 'mask' means. Intellij 14 + lombok: @Slf4j Cannot find symbol log, Lombok excluding field with @ToString.Exclude is not working. You can change the name used to identify the member with @ToString.Include(name = "some other name"), and you can change the order in which the members are printed via @ToString.Include(rank = -1). The ToString.Exclude solution seems like an overkill at a first glance, because that completely defeats the purpose of this feature if there's always some random field missing. Of course, this is just a suggestion, and I am interested in the feedback relating to whether other people who use the most popular frameworks have the same issues. The masker method solution is some boilerplate, but as I'll show later (in the cost section), also has crucial advantages. private List employees; // Replacing any other POJO: #jpa #hibernate #eclipselink #intellijidea #java #kotlin #jpabuddy #lombokBy default, Lombok @ToString implementation prints the class name and all the fields, including the lazy ones. If you want to skip some fields, you can annotate these fields with @ToString.Exclude. Ideally, you could configure this setting on both a class level (via @tostring and @DaTa) annotations and on a global level (via lombok.config). You should never design your API so that other code is forced to parse your toString() output anyway! Do large language models know what they are talking about? They are not falsifiable; such statements cannot usefully be part of a debate. the least amount of effort, making the decisions and just specifying the Members without a rank are considered to have rank 0, members of a higher rank are printed first, and members of the same rank are printed in the same order they appear in the source file. @Exclude is nothing but @ToString.Exclude only. Currently use workaround (thanks to @Maaartinus ) but such approach looks ugly and not error-prone. 1. . The contrast is forgetting the entire lombok @ToString feature. If this worries you, you can always shove an @Exclude on the field and close this loophole!) We could by default (possibly have a config key) exclude fields annotated with @JsonBackReference, both from the ToString and from EqualsAndHashCode. I'm using Lombok to remove boilerplate code. @Data is a convenient shortcut annotation that bundles the features of @ToString, @EqualsAndHashCode, @Getter / @Setter and @RequiredArgsConstructor together: In other words, @Data generates all the boilerplate that is normally associated with simple POJOs (Plain Old Java Objects) and beans: getters for all fields, setters for all non-final fields, and appropriate toString, equals and hashCode implementations that involve the fields of the class, and a constructor that initializes all final fields, as well as all non-final fields with no initializer that have been marked with @NonNull, in order to ensure the field is never null. Various well known annotations about nullity cause null checks to be inserted and will be copied to the relevant places (such as the method for getters, and the parameter for the constructor and setters). To address a dubious practice (I think you're in a bit more trouble than just needing to fix some toStrings if sensitive info makes it quite this far), and to avoid the boilerplate of: That's not good enough. ArrayList. Do you want it to be put on the back-reference, and it should mean "when converting this field to a string, just use a specific getter method of the referenced value"? It means that if you do rework that toString (which, as per point 1 you do a lot), it is somewhat easy to accidentally forget to re-apply the masking code, resulting in a security issue. It also implies this should be explicitly documented as a common issue (or better, as a prerequisite) in the ToString documentation, which currently doesn't contain strings like "bi" or "recur", just barely a reference to arrays containing themselves: Arrays are printed via Arrays.deepToString, which means that arrays that contain themselves will result in StackOverflowErrors. However, this behaviour is no different from e.g. to your account. If you are so critical of my feedback, please point out what [FEATURE] Configuration Option for @ToString to print in JSON - GitHub Add try/catch SOEx, but only to expand on the message. Do large language models know what they are talking about? I'm afraid, it can't do any better than generating. Writing documentation For example, instead of printing birthdate, print from a baked in set of population ranges. Currently this is vaguely possible by overriding the default toString, but requires manually writing the toString method, which is especially non-trivial if @Builder.Default has been used: Describe the target audience to your account, When logging certain classes, it would be good not to exclude fields with sensitive data with @ToString.Exclude, but rather just mask their values with arbitrary value, e,g, ********. analyze the available options and their possible impact. Using this annotation lets us automatically configure the generated builder class to work with Jackson's deserialization. privacy statement. Sign in This would work nicely with @UtilityClass. As a hypothetical, let's say you have 20 fields in the class, and 2 need masking.
