• IDEA Lombok插件


    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?

    偶然知道还有Lombok少写代码的这种Coding神器,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 

    注解 作用
    @ToString  自动生成ToString方法
    @Getter@Setter  自动生成Getter和Setter方法
    @Slf4j 自动生成一个使用Slf4j的log常量,无需再声明log,coding可直接log.info

    官方介绍

    注解 作用
    @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?"
