mybatis自动生成代码

第一步:先下载jar包，mybatis-generator-core-1.3.2.jar， mysql-connector-java-5.1.13.jar；
第二步:编写需要生成代码的xml(根据实际的DB, 路径编写)
<?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="F:/mybatis/mysql-connector-java-5.1.13.jar"/><context id="my" targetRuntime="MyBatis3">    <commentGenerator>        <property name="suppressDate" value="false"/>        <property name="suppressAllComments" value="true"/>    </commentGenerator>    <jdbcConnection driverClass="com.mysql.jdbc.Driver"                    connectionURL="jdbc:mysql://182.254.128.241:4780/product_wms_test" userId="cdb_outerroot"                    password="zaq1CDE#"/>    <javaModelGenerator targetPackage="cn.eeka.productwms.entity.biz"                        targetProject="F:/mybatis/wms/entity">        <property name="enableSubPackages" value="true"/>        <property name="trimStrings" value="true"/>    </javaModelGenerator>    <sqlMapGenerator targetPackage="mappers"                     targetProject="F:/mybatis/wms/mapper">        <property name="enableSubPackages" value="true"/>    </sqlMapGenerator>    <javaClientGenerator targetPackage="cn.eeka.productwms.dao.biz"                         targetProject="F:/mybatis/wms/dao" type="XMLMAPPER">        <property name="enableSubPackages" value="true"/>    </javaClientGenerator>    <table tableName="PM_ProductInBound" domainObjectName="ProductInBound"           enableCountByExample="false" enableUpdateByExample="false"           enableDeleteByExample="false" enableSelectByExample="false"           selectByExampleQueryId="false">    </table>    <table tableName="PM_ProductInBoundDetail" domainObjectName="ProductInBoundDetail"           enableCountByExample="false" enableUpdateByExample="false"           enableDeleteByExample="false" enableSelectByExample="false"           selectByExampleQueryId="false">    </table></context>

</generatorConfiguration>

第三步: 执行命令
打开命令窗口，切换到mybatis所在包的路径下面，输入命令: java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig.xml -overwrite

或者 直接双击".bat"文件

注意: xml里面涉及到的一些路径配置，需要根据自己的实际情况填写正确，
如果执行后出现报错，一般有两种原因:
a.把xml中的中文注释都去掉;
b.把xml的编码格式转换成UTF-8 无BOM格式的;
