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> </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。
