resource中配置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">
<generatorConfiguration>

    <context id="DB2Tables" targetRuntime="MyBatis3">
        <!-- 注释 -->
        <commentGenerator>
            <property name="suppressAllComments" value="true" /><!-- 是否取消注释 -->
            <property name="suppressDate" value="false" /> <!-- 是否生成注释代时间戳 -->
        </commentGenerator>

        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/video" userId="root"
                        password="root">
        </jdbcConnection>


        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <javaModelGenerator targetPackage="com.example.demo.entity"
                            targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="com.example.demo.entity"
                         targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="cn.llk.bootdemo.dao" targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <table tableName="pr_admin_users" domainObjectName="pr_admin_users"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
            <!-- 数据库表主键 -->
            <generatedKey column="id" sqlStatement="Mysql" identity="true" />
        </table>

    </context>
</generatorConfiguration>

pom.xml
注意:一定要在这里配置MySQL的依赖,否则会报找不到MySQL驱动的错
