JAVA 使用MyBatis Generator Tool工具生成代码

1.下载所需jar包： mybatis-generator-core 和数据库链接jar包 mysql-connector-java

2.配置生成文件  hp-generator.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>
 
	<!-- 指定数据连接驱动jar地址 -->
	<classPathEntry location="D:\Project\EclipseWorkSpace\jar\mysql-connector-java-5.0.3-bin.jar" />
 
 
	<context id="my" targetRuntime="MyBatis3">
		<commentGenerator>
			<property name="suppressAllComments" value="false" /><!-- 是否取消注释 -->
			<property name="suppressDate" value="true" /> <!-- 是否生成注释代时间戳 -->
		</commentGenerator>
 
 
 
		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
			connectionURL="jdbc:mysql://127.0.0.1:3306/cy32_rbac?useUnicode=true&amp;characterEncoding=UTF-8" userId="root"
			password="" />
 
		<!-- 生成实体类地址 -->
		<javaModelGenerator targetPackage="com.shxt.framework.rbac.user.model"
			targetProject="D:\Project\EclipseWorkSpace\Mybatis-generator">
			<property name="enableSubPackages" value="true" />
			<property name="trimStrings" value="true" />
		</javaModelGenerator>
 
		<!-- 生成mapxml文件 -->
		<sqlMapGenerator targetPackage="com.shxt.framework.rbac.user.model"
			targetProject="D:\Project\EclipseWorkSpace\Mybatis-generator">
			<property name="enableSubPackages" value="true" />
		</sqlMapGenerator>
 
		<!-- 生成mapxml对应client，也就是接口dao -->
		<javaClientGenerator targetPackage="com.shxt.framework.rbac.user.dao"
			targetProject="D:\Project\EclipseWorkSpace\Mybatis-generator" type="XMLMAPPER">
			<property name="enableSubPackages" value="true" />
		</javaClientGenerator>
 
 
 
 
		<table tableName="sys_user" domainObjectName="User" >
			<property name="constructorBased" value="false"/>
			<property name="ignoreQualifiersAtRuntime" value="false"/>
			<property name="modelOnly" value="false"/>
			<property name="userActualColumnNames" value="true"/>
		</table>
 
 
	</context>
 
</generatorConfiguration>

需要修改配置文件中的一下几个部分：

 

打开cmd框：

执行一下命令：

java -jar mybatis-generator-core-1.3.5.jar -configfile hp-generator.xml -overwrite

然后将生成的文件夹，粘贴的工程的src下响应的目录即可。
