新老客户大回馈,云服务器低至5折

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

  • @Getter@Setter 

    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?"
