mybatis 代码自动生成（dao、mapping、bean）

一步：需要
mybatis-generator-core-1.3.5.jar
sqljdbc4.jar
generatorConfig.xml

generatorConfig.xml文件编码：

<?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-8.0.11.jar"/>    
    <context id="DB2Tables"  targetRuntime="MyBatis3">    

        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost/bxy_demo?serverTimezone=GMT%2B8" userId="root" password="123456">          </jdbcConnection>    
        <javaTypeResolver>    
            <property name="forceBigDecimals" value="false"/>    
        </javaTypeResolver>    


        <!-- 生成Model类存放位置 -->
        <javaModelGenerator targetPackage="com.model" targetProject="src">    
            <property name="enableSubPackages" value="true"/>    
            <property name="trimStrings" value="true"/>    
        </javaModelGenerator>    

        <!-- 生成映射文件存放位置 -->
        <sqlMapGenerator targetPackage="com.mapping" targetProject="src">    
            <property name="enableSubPackages" value="true"/>    
        </sqlMapGenerator>    

        <!-- 生成dao类存放位置 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.dao" targetProject="src">    
            <property name="enableSubPackages" value="true"/>    
        </javaClientGenerator>    

        <!-- 生成对应表及类名  tableName:数据库表名，domainObjectName:生成的类名-->
        <table tableName="orderfrom" domainObjectName="Orderfrom" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>  
        <table tableName="materiel" domainObjectName="Materiel" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>  
    </context>    
</generatorConfiguration>   

二步：
打开控制台 cmd
进入该文件夹

三步:
执行
java -jar mybatis-generator-core-1.3.5.jar -configfile generatorConfig.xml -overwrite
完成
