5. 面向接口编程三层架构文件

• (1)UserController

package cn.jasonjing.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;

import cn.jasonjing.domain.User;
import cn.jasonjing.service.UserService;

@Controller
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("/getUsers")
    @ResponseBody
    public List getAllUsers(){
        List userList = userService.findAllUsers();
        return userList;
    }

    @RequestMapping("/user")
    public ModelAndView getUser(){
        ModelAndView mv = new ModelAndView();


        List userList = userService.findAllUsers();
        mv.addObject("user", userList.get(0));
        return mv;
    }
}

• (2) UserService

package cn.jasonjing.service;

import java.util.List;

import cn.jasonjing.domain.User;

public interface UserService {

    public List findAllUsers();
}

• (3)UserServiceImpl

package cn.jasonjing.service.impl;

import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import cn.jasonjing.dao.UserMapper;
import cn.jasonjing.domain.User;
import cn.jasonjing.service.UserService;


@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper userMapper;


    @Override
    public List findAllUsers() {
        List userList = userMapper.findAllUsers();
        return userList;
    }

}

• (4)UserMapper

package cn.jasonjing.dao;

import java.util.List;

import cn.jasonjing.domain.User;

public interface UserMapper {

    public List findAllUsers();

}

• (5)UserMapper.xml

<mapper namespace="cn.jasonjing.dao.UserMapper">
    <select  id="findAllUsers"  resultType="cn.jasonjing.domain.User">
        select * from tb_user
    select>
mapper>

• (6)User

package cn.jasonjing.domain;

public class User {

    private int id;
    private String username;
    private String password;
    private String phone;
    private String email;
    private String created;
    private String updated;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public String getPhone() {
        return phone;
    }
    public void setPhone(String phone) {
        this.phone = phone;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public String getCreated() {
        return created;
    }
    public void setCreated(String created) {
        this.created = created;
    }
    public String getUpdated() {
        return updated;
    }
    public void setUpdated(String updated) {
        this.updated = updated;
    }

}

6.前端显示

这里只显示了一点点内容，属于仅仅测试一下
http://localhost:8080/SSM/user

user.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>


<html>
  <head>
    <base href="<%=basePath%>">

    <title>My JSP 'index.jsp' starting pagetitle>
    <meta http-equiv="pragma" content="no-cache">
    <meta http-equiv="cache-control" content="no-cache">
    <meta http-equiv="expires" content="0">    
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="This is my page">
    
  head>

  <body>
    This is my JSP page. <br>
    ${user.id }<br>
    ${user.username }<br>
    ${user.password }<br>



  body>
html>
