文件准备：eclipse mybatis generator插件、mysql-connector-java.jar、mybatis-generator-core.jar

文件下载：[http://pan.baidu.com/s/1kVDf0of][http_pan.baidu.com_s_1kVDf0of]

## **一、eclipse插件方式生成代码：** ##

1.下载eclipse mybatis generator插件：  
2.将features和plugins中的文件copy到eclipse对应的目录下；  
3.启动eclipse，可以看到插件已成功安装。

4.一般使用maven管理项目，需要配置pom.xml

<dependency>
    			<groupId>mysql</groupId>
    			<artifactId>mysql-connector-java</artifactId>
    			<version>5.1.38</version>
    		</dependency>
    			<groupId>mysql</groupId>
    			<artifactId>mysql-connector-java</artifactId>
    			<version>5.1.38</version>
    		</dependency>

<dependency>
    			<groupId>org.mybatis.generator</groupId>
    			<artifactId>mybatis-generator-core</artifactId>
    			<version>1.3.2</version>
    		</dependency>

5.在项目resource目录下创建配置文件generatorConfig.xml

6.配置文件实例：

<?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="H:\mybatis\mysql-connector-java-5.1.39.jar" />
    	<context id="DB2Tables" targetRuntime="MyBatis3">
    		<commentGenerator>
    			<property name="suppressAllComments" value="false" />
    			<property name="suppressDate" value="true" />
    		</commentGenerator>
    		
    		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
    			connectionURL="jdbc:mysql://localhost:3306/mydb?characterEncoding=utf8"
    			userId="root" password="123456">
    		</jdbcConnection>
    		<javaTypeResolver>
    			<property name="forceBigDecimals" value="false" />
    		</javaTypeResolver>
    		
    		<javaModelGenerator targetPackage="com.cms.pojo"
    			targetProject="cms_sys">
    			<property name="enableSubPackages" value="true" />
    			<property name="trimStrings" value="true" />
    		</javaModelGenerator>
    		
    		<sqlMapGenerator targetPackage="com.cms.mapping"
    			targetProject="cms_sys">
    			<property name="enableSubPackages" value="true" />
    		</sqlMapGenerator>
    		
    		<javaClientGenerator type="XMLMAPPER"
    			targetPackage="com.cms.dao" targetProject="cms_sys">
    			<property name="enableSubPackages" value="true" />
    		</javaClientGenerator>
    		
    		<table schema="CL_DEMO" tableName="tb_user" />
    		<table schema="CL_DEMO" tableName="tb_task" />
    		<table schema="CL_DEMO" tableName="tb_config" />
    		<table schema="CL_DEMO" tableName="tb_sprint" />
    	</context>
    </generatorConfiguration>  targetProject为项目名称 -->
    		<javaModelGenerator targetPackage="com.cms.pojo"
    			targetProject="cms_sys">
    			<property name="enableSubPackages" value="true" />
    			<property name="trimStrings" value="true" />
    		</javaModelGenerator>
    		
    		<sqlMapGenerator targetPackage="com.cms.mapping"
    			targetProject="cms_sys">
    			<property name="enableSubPackages" value="true" />
    		</sqlMapGenerator>
    		
    		<javaClientGenerator type="XMLMAPPER"
    			targetPackage="com.cms.dao" targetProject="cms_sys">
    			<property name="enableSubPackages" value="true" />
    		</javaClientGenerator>
    		
    		<table schema="CL_DEMO" tableName="tb_user" />
    		<table schema="CL_DEMO" tableName="tb_task" />
    		<table schema="CL_DEMO" tableName="tb_config" />
    		<table schema="CL_DEMO" tableName="tb_sprint" />
    	</context>
    </generatorConfiguration>

7.选择该配置文件，右键generate MyBatis/iBATIS Artifacts，项目对应包路径将自动生成MyBatis相关文件。

## **二、windows命令行方式生成代码：** ##

配置文件与上文提到 的一样，只不过targetProject须改为你想要存放文件的路径如：H:\\mybatis\\src

**![SouthEast 1][]**

java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite

**![SouthEast 2][]**

将会在src下生成代码实例：
