IDEA Lombok插件

Posted 2020-12-24 caizhiqin

新公司大家都用idea，最终舍弃eclipse入乡随俗，失去了一些功能，也得到了一些功能，用了两个月终于习惯后感觉比eclipse更好用？

Lombok

偶然知道还有Lombok少写代码的这种Coding神器，感觉自己果真是out了，使用其注解能够在我们编译源码的时候自动为我们生成很多Code。

 

 

依赖

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.0</version>
    <scope>provided</scope>
</dependency>

好用的几个注解

• @ToString 

　　　　自动生成ToString

• @[email protected] 

　　　　自动生成Getter和Setter方法

• @Slf4j

　　　　自动生成一个log常量，无需再声明log，coding可直接log.info

官方介绍

• @NonNull

　　　　or: How I learned to stop worrying and love the NullPointerException.

• @Cleanup

　　　　Automatic resource management: Call your close() methods safely with no hassle.

• @Getter/@Setter

　　　　Never write public int getFoo() {return foo;} again.

• @ToString

　　　　No need to start a debugger to see your fields: Just let lombok generate a toString for you!

• @EqualsAndHashCode

　　　　Equality made easy: Generates hashCode and equals implementations from the fields of your object..

• @NoArgsConstructor, @RequiredArgsConstructor and @AllArgsConstructor

　　　　Constructors made to order: Generates constructors that take no arguments, one argument per final / non-nullfield, or one argument for every field.

• @Data

　　　　All together now: A shortcut for @ToString, @EqualsAndHashCode, @Getter on all fields, and @Setter on all non-final fields, and @RequiredArgsConstructor!

• @Value

　　　　Immutable classes made very easy.

• @Builder

　　　　... and Bob‘s your uncle: No-hassle fancy-pants APIs for object creation!

• @SneakyThrows

　　　　To boldly throw checked exceptions where no one has thrown them before!

• @Synchronized

　　　　synchronized done right: Don‘t expose your locks.

• @Getter(lazy=true)

　　　　Laziness is a virtue!

• @Log

　　　　Captain‘s Log, stardate 24435.7: "What was that line again?"
