小試Lombok，簡化Java代碼

    Lombok 可以幫助我們減少java中冗長的代碼，也算是一種註解式的自動生成工具。

 

    下載安裝

 

    網址：http://projectlombok.org

 

    自動安裝：進入到存放 lombok.jar 的那個目錄，並鍵入 java -jar lombok.jar 。

    或

    手動安裝：

1.     將lombok.jar copy到eclipse的安裝目錄。
2.     修改eclipse.ini文件，加入如下 代碼

     -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（自動生成getters,setters）






import lombok.Data


public @Data class Lure {


	private String name;


	private int size;


	private String color;


	private String style;


}




其他屬性還有

@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 even get 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
