第一步：Spring整合MyBatis
请参考：http://www.leonwish.com/archives/88
第二步：将SpringMVC整合进入Spring和MyBatis
- 修改UserServiceImpl.java
package com.royotech.service.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.royotech.dao.PersonDAO;
import com.royotech.entity.Person;
import com.royotech.service.UserService;
@Service
public class UserServiceImpl implements UserService{
@Autowired
private PersonDAO personDAO;
@Override
public List<Person> select() {
return personDAO.selectAll();
}
}
- applicationContext.xml头部增加scanner语句。
<context:component-scan base-package="com.royotech.service"></context:component-scan>- web.xml增加filter
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>- 撰写controller
package com.royotech.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.royotech.entity.Person;
import com.royotech.service.UserService;
@Controller //作用：将当前类的对象交给Spring工厂创建
@RequestMapping("user") //请求路径
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("select") //请求路径
public String select(Model model) {
List<Person> listPerson = userService.select();
model.addAttribute("listPerson",listPerson);
return "forward:/list.jsp";
}
}- 撰写list.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Welcome!</title>
</head>
<body>
<c:forEach var="person" items="${listPerson}">
${person.id},${person.name},${person.birthday},${person.telephone},${person.address}<br/>
</c:forEach>
</body>
</html>- 大功告成，测试结果如下：
