SpringMVC整合mybatis实例代码

MyBatis 本是apache的一个开源项目iBatis, 2010年这个项目由apache software foundation 迁移到了google code，并且改名为MyBatis 。

一、逆向工程生成基础信息

PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"

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

connectionURL="jdbc:mysql://localhost:3307/mybatis" userId="root"

password="jalja">

connectionURL="jdbc:mysql://localhost:3307/mybatis" userId="root"

password="jalja">

targetProject=".\src">

targetPackage="com.jalja.springmvc_mybatis.mapper"

targetProject=".\src">

targetPackage="com.jalja.springmvc_mybatis.mapper"

targetProject=".\src">

public static void main(String[] arhs) throws Exception{

List warnings = new ArrayList();

boolean overwrite = true;

File configFile = new File("src.main.resources/generator.xml");

ConfigurationParser cp = new ConfigurationParser(warnings);

Configuration config = cp.parseConfiguration(configFile);

DefaultShellCallback callback = new DefaultShellCallback(overwrite);

MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);

myBatisGenerator.generate(null);

}

二、springMVC与Mybatis整合各个配置文件

1.项目结构

2、各个文件的核心代码
