Welcome to the lombok javadoc. Project Lombok is a mature library that reduces boilerplate code.

For example, in some cases large objects require several fields to be populated, which can be problematic when such an object is implemented via a constructor.Lombok makes it simple to create builder objects in much the same way that it enables easy POJO creation.

This can be handy if you wish to develop a custom getter or setter for one or more of the class fields.If you are merely interested in having constructors generated aically, You might be asking yourself, “Can’t my IDE already do that sort of refactoring?” Most modern IDEs—such as NetBeans, Eclipse, and IntelliJ—offer features such as encapsulation of fields and auto-generation of code. These abilities are great because they can significantly increase productivity. This page can also contain an overall description of the set of packages. How often have you either forgotten to close a resource or written lots of boilerplate Although the Java language now contains the try-with-resources statement to help close resources, It is important to note that in a case where code throws an exception and then subsequent code invoked via To ensure safety by having only one thread that can access a specified method at a time, the method should be marked as This solution can be a safer alternative to using the Most logging requires some declaration to set up a logger within each class. If you’re using Lombok, you simply change the field name and move on with your life.Sometimes it is useful to have the ability to develop a builder object, which allows objects to be constructed using a step-by-step pattern with controlled construction. You probably want to look at the feature documentation. Also, what happens when you decide to change one of your field names? How to Configure Project Lombok to IDE? This somewhat contentious ability should be used carefully, of course. Although developing accessor methods is easy, they generally are just boilerplate code.

How many lines of code will be needed to generate You can annotate a class with a @Getter or @Setter annotation. Step 1: Go to File > Settings > Plugins.

Project Lombok is a java library that aically plugs into your editor and build tools, spicing up your java. Captain's Log, stardate 24435.7: "What was that line again?" Step 3: Search for Lombok plugin. The cases mentioned above cover just a few of those where Project Lombok can be a great benefit. The delombok utility can be applied to your code to convert code that uses Lombok back to vanilla Java. Lombok, made to order: Configure lombok features in one place for your entire project or even your workspace. The Writing a POJO can be laborious, especially if there are many fields.

To boldly throw checked exceptions where no one has thrown them before! That’s a lot of clutter.

Lombok can take care of the logger declaration if you place the For instance, if you wish to use a logging API—say, Log4j 2—each class that uses the logger must declare something similar to the following:Lombok makes it possible to do the following instead:There are several other useful features Lombok offers that I haven’t yet covered. Running delombok Delombok copies your source files to another directory, replacing all lombok annotations with their desugared form. These annotations also accept an optional parameter to designate the access level if needed. Let’s say your Java object has 10 fields. The code generated by lombok will not ignore, wrap, replace, or otherwise modify the thrown checked exception; it simply fakes out the compiler. Introduction In this post, we are going to write about Project Lombok, a must-have tool for every Spring programmer.
