mybatis生成代码方式

    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
