关于Idea IDE可以自动生成java代理的生产过程栗子

1、新建一个java类，

package reusing;
<span style="color:#808080;">/*

<span style="color:#808080;">  Created by caoxiaohong on 16/11/20.

<span style="color:#808080;">  测试idea可以手动选择生成代理

<span style="color:#808080;"> 

<span style="color:#808080;"> */

<span style="color:#000080;">public class SpaceShipDelegation {}

2、在一个要被代理的类，如下：

class SpaceShipControls{
    void up(int i){}
    void down(int i){}
    void left(int i){}
    void right(int i){}
    void forward(int i){}
    void back(int i){}
}

3、在类一个代理类的变量，如下：

public class SpaceShipDelegation {
    private SpaceShipControls controls=new SpaceShipControls();
}

显示如下：

选择Generate，后显示如下：

选择：Delegate Methods,然后显示如下：

选择ok，显示如下：

选择ok,显示如下：

这样就自动生成了java类的代理，也完成了idea自动生成java代理的过程。
sum：整体代码如下：
