mybatis逆向生成javaBean

大家好：

最近在学习搭建框架，但是大量的表结构，如何直接生成javaBean代码，困扰着我，作为笔记，记录一下！如有疑问可参与讨论！

Mybatis逆向生成代码

方法一：
自行写代码解决问题：
generatorConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration

  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

官方配置

下载插件

http://pan.baidu.com/s/1dEZfkPV

打开‘MyBatis_Generator_1.3.1.zip’文件并解压解压为2个文件夹 features/plugins 将其放进eclipse的安装处：

重启eclipse –>new ->mybatis generator configuration file

创建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 >
<classPathEntry location="E:/mysql-connector-java-5.1.26-bin.jar"/>

  <context id="context1" targetRuntime="MyBatis3">
    <jdbcConnection driverClass="com.mysql.jdbc.Driver" 
    	connectionURL="jdbc:mysql://localhost:3306/yinghuameng" 
    	userId="root" 
    	password="root" />
    <javaModelGenerator targetPackage="com.yinghuameng.pojo" targetProject="yinghuameng-manager-web" />
    <sqlMapGenerator targetPackage="com.yinghuameng.mapper" targetProject="yinghuameng-manager-web" />
    <javaClientGenerator targetPackage="com.yinghuameng.mapper" targetProject="yinghuameng-manager-web" type="XMLMAPPER" />
    <!-- 指定数据库表 -->
		<table schema="" tableName="tb_cart"></table>
		<table schema="" tableName="tb_content"></table>
		<table schema="" tableName="tb_content_category"></table>
		<table schema="" tableName="tb_item_jd"></table>
		<table schema="" tableName="tb_item_jd_desc"></table>
		<table schema="" tableName="tb_item_param"></table>
		<table schema="" tableName="tb_item_param_item"></table>
		<table schema="" tableName="tb_order"></table>
		<table schema="" tableName="tb_order_item"></table>
		<table schema="" tableName="tb_order_shipping"></table>
		<table schema="" tableName="tb_user"></table>
  </context>
</generatorConfiguration>

右击xml文件 -》generate mybatis/ibatis artifacts 生成javaBean

注意：

此处的 targetProject="yinghuameng-manager-web" 指的是项目
