小试Lombok，简化Java代码

    Lombok可以帮助我们减少java中冗长的代码，也算是一种注解式的自动生成工具。

 

    下载安装

 

    网址：http://projectlombok.org

 

    自动安装：进入到存放 lombok.jar 的那个目录，并键入 java -jar lombok.jar。

    或

    手动安装：

1.     将lombok.jar copy到eclipse的安装目录。
2.     修改eclipse.ini文件，加入如下 代码

     -Xbootclasspath/a:lombok.jar  
     -javaagent:lombok.jar 

 

原始JavaBean

public class Lure {

private String name;

private int size;

private String color;

private String style;

}



使用Lombok（自动生成getters,setters）




import lombok.Data

public @Data class Lure {

private String name;

private int size;

private String color;

private String style;

}



其他属性还有

@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.

@Data

All together now: A shortcut for @ToString, @EqualsAndHashCode,@Getter on all fields, and @Setter on all non-final fields. You evenget a free constructor to initialize your final fields!

@Cleanup

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

@Synchronized

synchronized done right: Don't expose your locks.

@SneakyThrows
