1.項目結構：
2.代碼：
1.User.xml Article.java User.javaI UserOperation.java：參考mybatis快速使用
2.UserController.java：請求處理
package com.spring3.controller;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.mybatis.bean.Article;
import com.mybatis.service.IUserOperation;
@Controller
@RequestMapping("/article")
public class UserController {
@Autowired
//類型注入
IUserOperation userMapper;
@RequestMapping("/list")
public ModelAndView listall(HttpServletRequest requset,HttpServletResponse response){
List<Article> articles = userMapper.getUserArticles(1);
ModelAndView mav = new ModelAndView("list");
mav.addObject("articles", articles);
return mav;
}
}
3.Configuration.xml：可以不再導入mapper
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

<property name="password" value="root"/>
</dataSource>
</environment>
</environments>
<!-- <mappers>
<mapper resource="com/mybatis/bean/User.xml"/>

</configuration>4.applicationContext.xml：配置數據源、sqlsessionfactory、事務、實例化接口類mapper bean

<!-- 掃描包 使用分號或逗號 作爲分隔符設置多於一個的包路徑-->

</beans>7.測試：
<body>
<c:forEach items="${articles }" var="item">
${itme.id}--${item.title }--${item.content }<br/>
</c:forEach>
</body>
3.總結：
1.configuration.xml文件中的數據庫配置可以不用
2.其他配置和spring+mybatis一樣，唯有spring配置文件在 實例化mapper時配置略有不同，不過都是通過MapperFactoryBean去實例化接口mapper。
@Autowired類型注入
