, their implementations are completely different. As a result, Lombok comes with two sets of annotation handlers (hooks to code in Lombok and included Code generation logic): one for each compiler. Fortunately, this is transparent, so as a user, we only have to face a set of Java annotations.Lombok also provides tight integration with eclipse: Saving Java files automatically triggers

Introduction:Using Lombok in a project can reduce the writing of a lot of repetitive code. For example, compile the getter/setter/tostring method.
Introduce dependency:Add the Lombok dependency jar to the project and add the following parts to the POM file. (It is unclear that the version can be searched in the m

We usually define a lot of javabean in the development process, and then use the IDE to generate the constructor, getter, setter, equals, Hashcode, tostring method of its properties, when you want to change a property, such as name, type, etc. Need to recreate the methods mentioned above, is there any way in Java to avoid this repetitive work? The answer is yes, let's take a look at the picture below, the right side is a simple javabean, only two attributes are defined, the @data is
This annotation can automatically create the methods of Get, set, ToString, Eaquls, hashcode, etc.@NoArgsConstructor This is a parameterless constructor@AllArgsConstructor Full parameter constructor@Setter Set method@Getter Get methodOf course there are some specific usage and detailed questions can refer to the official website, here is a small video, speak very goodTip: Install Lombok plug-ins in IJFirst download
When writing to use Java, there will inevitably be some template code to write, otherwise get/set,tostring, hashcode, close resources, define constructors and so on. The code will look very redundant and very long. Lombok project can be we get rid of these things, through a series of annotations, Lombok can help us to automatically generate these functions.Lombok website Address: https://projectlombok.org/R

As we all know, the Java language is verbose, write long will find many places of code look very redundant. lombokprovides a solution for simplifying Java code that is annotated to generate templated code. The most typical is the constructor that generates the class, the Getter/setter,tostring method, and so on.
Annotations are a feature that accompanies the JDK5 release, which is divided into source,class (compile stage) and runtime, depending on the life cycle.
