   a.配置模板

   b.连接数据库

   c.生成代码



 

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

    安装方法与激活方法一样,该插件用于代码规约检查

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

   安装方法与激活方法一样,该插件用于代码生成

   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
