mybatis逆向工程(eclipse版本)

1. 新建maven项目, 目录结构

2. src/main/resources中新建generatorConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

         <plugin type="org.mybatis.generator.plugins.ToStringPlugin"></plugin> 
        <commentGenerator>
            <!-- 这个元素用来去除指定生成的注释中是否包含生成的日期 false:表示保护 -->

            <property name="suppressDate" value="true" />
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true" />
