面试的时候，有问起这个lombok是什么玩意儿？ 当时没有使用过，感觉挺好奇的，简单研究了下

打开下方蓝色注解链接-有惊喜

lombok官方地址: https://projectlombok.org/download.html

 

使用Maven来添加支持

<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.16.10</version>
</dependency>

使用idea插件，需要安装，设置下。

 

 

 

 

 

 

 

 

 

 

 

 

 

下面贴一些官网的demo:

 

val

Finally! Hassle-free final local variables.

@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 atoString for you!

@EqualsAndHashCode

Equality made easy: Generates hashCode andequals 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-null field, 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?"

Configuration system

Lombok, made to order: Configure lombok features in one place for your entire project or even your workspace.

Experimental features

Here be dragons: Extra features which aren't quite ready for prime time yet.
