mybatis生成代码方式：  
1.下载mybatis-generator-core-1.3.2.jar  
2.下载数据库驱动包  
3.编写配置文件generator.xml 内容如下：  
<?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>  
<!-- 数据库驱动包位置 -->  
<classPathEntry location="C:Userslwx155211Desktoplolspringmybatistoolsojdbc14-10g.jar" />  
<!--<classPathEntry location="C:oracleproduct10.2.0db_1jdbclibojdbc14.jar" /> -->  
<context id="DB2Tables" targetRuntime="MyBatis3">  
<commentGenerator>  
<property name="suppressAllComments" value="true" />  
</commentGenerator>  
<!-- 数据库链接URL、用户名、密码 -->  
<!-- <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" connectionURL="jdbc:oracle:thin:@localhost:1521:orcl" userId="msa" password="msa">
-->  
<jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" connectionURL="jdbc:oracle:thin:@10.137.26.50:1521:INOMC" userId="portal" password="portal">  
</jdbcConnection>  
<javaTypeResolver>  
<property name="forceBigDecimals" value="false" />  
</javaTypeResolver>  
<!-- 生成模型的包名和位置 -->  
<javaModelGenerator targetPackage="com.mweb.mybatis.model" targetProject="D:workspace8mWebsrc">  
<property name="enableSubPackages" value="true" />  
<property name="trimStrings" value="true" />  
</javaModelGenerator>  
<!-- 生成的映射文件包名和位置 -->  
<sqlMapGenerator targetPackage="com.mweb.mybatis.mapping" targetProject="D:workspace8mWebsrc">  
<property name="enableSubPackages" value="true" />  
</sqlMapGenerator>  
<!-- 生成DAO的包名和位置 -->  
<javaClientGenerator type="XMLMAPPER" targetPackage="com.mweb.mybatis.dao" targetProject="D:workspace8mWebsrc">  
<property name="enableSubPackages" value="true" />  
</javaClientGenerator>  
<!-- 要生成那些表(更改tableName和domainObjectName就可以) -->  
<table tableName="t_m400_servicenum" domainObjectName="ServiceNum" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />  
<table tableName="t_m400_ecinfo" domainObjectName="EcInfo" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />  
</context>  
</generatorConfiguration>  
4.执行如下命令：  
java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite
