xml文件改成自己的数据库和配置需生成的表

generatorConfig.xml文件配置详情

<?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">
<generatorConfiguration>


    <!--此文件用于从数据库表结构，自动生成model，自动生成基础CURD的mapper代码 mvn mybatis-generator:generate-->
    <!--<properties resource="./generator/generatorConfig.properties"/>-->

    <!-- 数据库驱动包位置,使用maven的方法，这个就不用了 -->
    <context id="MYSQLTables" targetRuntime="MyBatis3" defaultModelType="flat">

        <!-- 生成的Java文件的编码 -->
        <property name="javaFileEncoding" value="UTF-8"/>
        <!-- 格式化java代码 -->

        <!-- 格式化XML代码 -->
        <property name="xmlFormatter" value="org.mybatis.generator.api.dom.DefaultXmlFormatter"/>

        <!--对于单表的分页实现limit offset-->
        <!--<plugin type="com.xxg.mybatis.plugins.MySQLLimitPlugin"></plugin>-->


        <plugin type="org.mybatis.generator.plugins.RowBoundsPlugin"></plugin>

        <commentGenerator>
            <property name="suppressAllComments" value="true" />
        </commentGenerator>
        <!-- 数据库链接URL、用户名、密码 -->

        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/d2?useUnicode=true&amp;characterEncoding=utf8&amp;autoReconnect=true"
                        userId="root"
                        password="123456">
        </jdbcConnection>

        <javaModelGenerator targetPackage="${targetModelPackage}" targetProject="${targetJavaProject}"/>

3、把application.properties修改成application.yml文件

修改.yml文件配置详情

.yml文件

server:
  port: 20001

4、修改pom.xml文件

5、执行 mybatis-generator:generate命令

6、代码生成完毕！

pom.xml文件配置详情
