![]() That being said, you might want to avoid using the Data annotation with your entity class ().Instead, explicitly use Getter and Setter. The ToString annotation can lead to stack overflow errors with lazy-loaded attributes, and the EqualsAndHashCode annotation can generate incorrect hashcodes and equality checks when used with. class files as per a number of project annotations we introduce in our code. ![]() ![]() repositories Code language: Java ( java produces complex builder APIs for your classes. The code you showed us above should be working, that is, assuming this is what you are really running to generate these errors. The way it works is by plugging into our build process and auto-generating Java bytecode into our. But, Data also does this, and Value also does this. Remove the Value annotation, and you should have setters in class A. To configure lombok with any build tool, you have to specify that the lombok dependency is required to compile your source code,but does not need to be present when running/testing/jarring/otherwise deploying your code. Theres a conflict between Value (which helps creating immutable classes) and Setter (which adds methods that mutates the class state). Lombok could require all direct subclasses of an abstract class to also use toBuilder by adding an abstract toBuilder () method on the abstract class. It improves developer productivity by reducing the amount of boiler plate to be written in your java programs by providing set of annotations. In fact, as Hossein Nasr already explained, Lombok cannot know whether there are subclasses that do not have toBuildertrue. Where is this exception thrown For both JpaRespository.findById() and leteById() the id must not be null or they will throw an 'IllegalArgumentException: The given id must not be null' but I can't see a path in your code where you would call either of these methods with a null argument. Project Lombok is a java library that seamlessly integrates with your editor and build tools, enhancing your java. If set to true, lombok will access fields directly instead of using getters (if available) when generating equals and hashCode methods.
