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

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?"
