Project Lombok is a boilerplate code remover and space saver that generates code in '.class' file instead of in the source code file.In this article, I will try to explain why Lombok is so popular. Lombok is a convenient tool that all Java developers should have in their toolkit. Then we can see what needs to be done to support it in IntelliJ. This means there are no fields we can rely on to calculate the hashCode.įor example, let’s create a test entity: class TestEntity = false)Īnd execute the following code: TestEntity testEntity = new TestEntity() Īssert.isTrue( set.contains(testEntity), "Entity not found in the set") lpandzic you should ask that in Lombok repo and not this plugin as first Lombok itself needs to support it.
Even the id of an entity is often generated by a database, so it gets changed after the entity is first persisted.
But when you are installing it in a new project or in a new computer after a long while, you might forgot to do the necessary steps to get it work in your IDE.

This article shows the most common issues you may face using Lombok with JPA entities. Lombok is a library that reduces boilerplate code when using the Java programming language. JUnit 5 but this tutorial is also valid for tools like Visual Code or IntelliJ. This is why we introduced a number of code inspections for Lombok to JPA Buddy. Project Lombok is a Java library tool that generates code for minimizing.
Analyzing the projects, we see people stumble into the same pitfalls over and over again. This often doesnt bring any real value to the business side of our programs, and thats where Lombok comes in to make us more productive. It is absolutely fine to use Lombok in your JPA projects, but it has some caveats. It is really strange to activate the annotation processor option in IntelliJ IDEA every time you import a project making use of lombok. Java is a great language, but it can sometimes get too verbose for common tasks we have to do in our code or compliance with some framework practices.

We develop JPA Buddy – a plugin for IntelliJ IDEA designed to make the use of JPA easier.
