首先要用到以下几个jar包（没有的可以自行上网搜索资源或者留言找我要哟~）

其中有mybatis框架的jar包，数据库驱动程序jar包以及MyBatis生成器jar包。其中的generatorConfig.xml是需要我们来配置的文件，配置如下：

<?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="mysql-connector-java-5.1.25-bin.jar"/>  
        <context id="DB2Tables"  targetRuntime="MyBatis3">  
            <commentGenerator>  
                <property name="suppressDate" value="true"/>  
                  
                <property name="suppressAllComments" value="true"/>  
            </commentGenerator>  
              
            <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://服务器IP地址/takoutShopping" userId="xxx" password="xxx">  
            </jdbcConnection>  
            <javaTypeResolver>  
                <property name="forceBigDecimals" value="false"/>  
            </javaTypeResolver>  
              
            <javaModelGenerator targetPackage="com.Takout.entitys" targetProject="src">  
                <property name="enableSubPackages" value="true"/>  
                <property name="trimStrings" value="true"/>  
            </javaModelGenerator>  
              
            <sqlMapGenerator targetPackage="mybatis.mapper" targetProject="src">  
                <property name="enableSubPackages" value="true"/>  
            </sqlMapGenerator>  
              
            <javaClientGenerator type="XMLMAPPER" targetPackage="com.Takout.dao" targetProject="src">  
                <property name="enableSubPackages" value="true"/>  
            </javaClientGenerator>  
              
            <table tableName="buyer" domainObjectName="Buyer" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
    		<table tableName="good" domainObjectName="Good" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
    		<table tableName="order" domainObjectName="Order" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
    		<table tableName="seller" domainObjectName="Seller" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
    		
        </context>  
    </generatorConfiguration>

大家根据相关的注释更改配置就好了。

完成上面这些配置，

接下来先在控制台定位到安装目录

再执行下列语句

java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig.xml -overwrite

即

这就生成好了。

现在我们就可以在src目录下找到相应的文件夹，每个表格都会对应三个文件（实体类、接口、配置文件）。

我们去看看。

好啦，这就都生成了。

大家可以自己去试一试啦~~
