MyBatis 自动生成mysql 表对应的javabean

1.所需的jar 包
  mybatis-3.0.4.jar  、mybatis-generator-core-1.3.1.jar 、 mysql-connector-java-5.1.13.jar
mybatis下载地址:http://code.google.com/p/mybatis/
2.新建文件夹
        新建文件夹E://mygen,将以上三个文件放入夹
3.同目录创建
  generator.xml 文件

<?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">

        </javaClientGenerator>  
        <!-- tableName:用于自动生成代码的数据库表；domainObjectName:对应于数据库表的javaBean类名 -->        
        <table tableName="achievement" domainObjectName="Achievement" schema="renwu"    enableInsert="true"  
        enableSelectByPrimaryKey="true" enableSelectByExample="false" enableDeleteByExample="false"   
        enableCountByExample="false" enableUpdateByExample="false">  
        <property name="useActualColumnNames" value="false" />  
         </table>       
        <table tableName="city" domainObjectName="City" schema="renwu"    enableInsert="true"  
        enableSelectByPrimaryKey="true" enableSelectByExample="false" enableDeleteByExample="false"   
        enableCountByExample="false" enableUpdateByExample="false">  
            <property name="useActualColumnNames" value="false" />  
        </table>     
</context>  
</generatorConfiguration>

4.执行命令完成。
  cmd ----E:-----cd E://mygen----Java -jar mybatis-generator-core-1.3.1.jar -configfile  generator.xml -overwrite
