首先，我们要下载jar包，访问下面网址，下载zip：

[https://github.com/mybatis/generator/releases][https_github.com_mybatis_generator_releases]

解压后目录如下，有人会问为什么没有generator.xml文件，是的，的确没有，要自己创建，下面会附上

主要看lib中标红的jar

这里还需要MySQL 驱动jar，网上自行下载，整理目录如下，我创建了mybatisGenerator文件，然后两个jar及xml都放在里面：

generator.xml内容如下，我已经添加了详细注释

<?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>
        
        <classPathEntry location="E:\mybatisGenerator\mysql-connector-java-5.1.40.jar" />
        <context id="DB2Tables" targetRuntime="MyBatis3">
            <commentGenerator>
                
                <property name="suppressDate" value="true" />
                <property name="javaFileEncoding" value="UTF-8"/>
            </commentGenerator>
            
            <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://192.168.5.222:3306/funk" userId="mysql-test" password="123456">
            </jdbcConnection>
            <javaTypeResolver>
                <property name="forceBigDecimals" value="false" />
            </javaTypeResolver>
            
            <javaModelGenerator targetPackage="com.jufan.risk.entity"
                                targetProject="E:\mybatisGenerator">
                <property name="enableSubPackages" value="true" />
                <property name="trimStrings" value="true" />
            </javaModelGenerator>
            
            <sqlMapGenerator targetPackage="com.jufan.risk.mapping"
                             targetProject="E:\mybatisGenerator">
                <property name="enableSubPackages" value="true" />
            </sqlMapGenerator>
            
            <javaClientGenerator type="XMLMAPPER" targetPackage="com.jufan.risk.mapper" targetProject="E:\mybatisGenerator">
                <property name="enableSubPackages" value="true" />
            </javaClientGenerator>
            
            <table tableName="manage_level" domainObjectName="manageLevel" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
            <table tableName="manage_level_company" domainObjectName="manageLevelCompany" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
     
            
        </context>
    </generatorConfiguration>

然后执行以下命令

发现多了个目录，没错，生成的文件都在里面了

好了，操作已经完成，是不是很简单，我在xml里面加的是两张表，所以每个文件夹下会生成两个文件，你们自己改自己配置即可，如果不成功，欢迎反馈！
