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>
<h2>MainPage</h2>
	<form action="user/showUser">
		<input type="submit" value="http://www.mamicode.com/user/showUser"/>
	</form>
