SSM框架整合详细教程（Spring+SpringMVC+Mabatis）

当前最火热的SSM框架整合教程，超级详细版

直接到正题，利用了最新稳定的框架

需要自己在Maven下搭建web工程

提示：实体类和mapping文件是通过MybatisGeneraor生成，详情百度，Service层只是简单的调用mapper

UserServiceImpl.java

package per.ssm.service.impl;

import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import per.ssm.mapper.UserMapper;
import per.ssm.service.UserService;
@Service
public class UserServiceImpl implements UserService {
	@Resource
	private UserMapper userMapper;
	@Override
	public String getUserById(String userId) {
		return userMapper.getName(userId);
	}

}

UserController.java

package per.ssm.controller;

import javax.servlet.http.HttpServletRequest;
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 per.ssm.service.UserService;  
  
@Controller
@RequestMapping("/user")  
public class UserController {  
	@Autowired
    private UserService userService; 
    @RequestMapping("/showUser")  
    public String toIndex(HttpServletRequest request,Model model){  
        String username = userService.getUserById("1");  
        model.addAttribute("username", username);  
        return "showUser";  
    }  
}

这是所需要的所有的配置文件，配置完成后，测试配置是否成功，

数据库里面先存了一条数据

index.jsp页面：

<html>
<body>
<h3>MainPage</h3>
	<form action="user/showUser">
		<input type="submit" value="user/showUser"/>
	</form>
</body>
</html>

showUser.jsp页面(页面在WEB-INF/views下面)

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>showUsere</title>
</head>
<body>
	用户名：${username }
</body>
</html>

点击提交显示数据库中的数据则成功。
