效果:

package com.machunqi;

/**
 * Created by machunqi@gmail.com on 2018/5/30 下午6:16
 */
public class User {
    public static void main(String[] args) {
        
    }
}

设置方法:

        File->Settings->File and Code Templates->Include->File Header-"添加以下代码"

/** 
 * Created by ${USER} on ${DATE} ${TIME}
 */  

如图:

*这里${USER}是默认电脑名,如果需要注释其他信息,可以自行修改,我这里设置的是个人邮箱.
