[开发十年，就只剩下这套Java开发体系了 >>> ][Java_ _]  ![hot3.png][]

## **一、首先，安装eclipse插件** ##

Help--Eclipser Marketplace中查找：Mybatis Generator 1.3.5安装

![Center][]

## **二、新建project** ##

New--other--查找如下

![Center 1][]

点击next，选择你要将文件生成到哪里的项目名

![Center 2][]

点击finish关闭。就会在hhh项目中生成文件generatorConfig.xml。

注意：hhh项目中要有[数据库][Link 1]相关jar包及要生成的包 mapper/pojo，因为一会要在配置文件中进行配置。

![Center 3][]

## **三、配置generatorConfig.xml** ##

<?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>  
        <context id="testTables" targetRuntime="MyBatis3">  
            <commentGenerator>  
                  
                <property name="suppressAllComments" value="true" />  
            </commentGenerator>  
              
              
            <jdbcConnection driverClass="oracle.jdbc.OracleDriver"  
                connectionURL="jdbc:oracle:thin:@150.16.17.22:1521:wsbs"   
                userId="hr"  
                password="hr123">  
            </jdbcConnection>   
      
              
            <javaTypeResolver>  
                <property name="forceBigDecimals" value="false" />  
            </javaTypeResolver>  
      
              
            <javaModelGenerator targetPackage="cn.herry.pojo"  
                targetProject="hhh/src">  
                  
                <property name="enableSubPackages" value="false" />  
                  
                <property name="trimStrings" value="true" />  
            </javaModelGenerator>  
              
            <sqlMapGenerator targetPackage="cn.herry.mapper"   
                targetProject="hhh/src">  
                  
                <property name="enableSubPackages" value="false" />  
            </sqlMapGenerator>  
              
            <javaClientGenerator type="XMLMAPPER"  
                targetPackage="cn.herry.mapper"   
                targetProject="hhh/src">  
                  
                <property name="enableSubPackages" value="false" />  
            </javaClientGenerator>  
              
              
            <table tableName="demo"></table>  
        </context>  
    </generatorConfiguration>

## **四、自动生成mapper.java和mapper.xml等文件** ##

右键generatorConfig.xml，选择如下：

![Center 4][]

之后，就可以在包下看到生成的文件了![得意][proud.gif]
