1.Alibaba Java Coding Guidelines
一、IDEA的下载安装激活
IDEA官网下载并安装,激活方法如下:设置——》插件——》Marketplace——》搜索eval——》选择IDE Eval Reset——》安装
二、IDEA实用插件安装
1.Alibaba Java Coding Guidelines
2.MybatisX
安装方法与激活方法一样,该插件用于mybatis相关代码提示跳转
3.Easy Code
a.配置模板
配置类,接口,枚举,注解
/**
* @author ${USER}
* @date ${DATE} ${TIME}
*/
配置模板,配置方法
/**
* @Description Todo
* @author $user$
* @date $date$ $time$
*/
创建类,接口,枚举,注解的效果
package com.example.demo;
/**
* @author Admin
* @Description Todo
* @date 2021/6/5 14:16
*/
public class Test {
}
配置模板,配置maven工程的mybatis和mybatis plus生成模板
