　　目錄結構

　　各個功能模塊的默認配置文件application.properties

#Thymeleaf的編碼
spring.thymeleaf.encoding=UTF-8

#熱部署靜態文件
spring.thymeleaf.cache=false

#使用HTML5的標准

實現過程分五步

　　1、用戶注冊功能
　　2、用戶登錄功能
　　3、管理員查詢用戶界面功能
　　4、用戶信息回顯功能
　　5、管理員修改用戶信息功能

　　controller控制層

　　service業務邏輯層

　　repository持久層

　　User實體　　設置主鍵ID自增

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Long id;
    private String username;
    private String password;
    private String telephone;

package com.Gary.GaryuserDemo.domain;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class User {
    
    
    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Long id;
    private String username;
    private String password;
    private String telephone;
    
    protected User() {
        
    }
    
    public User(Long id,String username,String password,String telephone) {
        this.id=id;
        this.username=username;
        this.password=password;
        this.telephone=telephone;
    }
    
    public Long getId() {
        return id;
    }
    public void setId(Long 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 getTelephone() {
        return telephone;
    }
    public void setTelephone(String telephone) {
        this.telephone = telephone;
    }

}

User.java

　　controller層獲接收用戶和管理員請求並做相應的回應

    //訪問首頁面
    @RequestMapping("/")
    public ModelAndView index()

    //用戶注冊
    @RequestMapping("/register.action")
    public ModelAndView register(User user)

    //用戶登錄
    @RequestMapping("/login.action")
    public ModelAndView login(User user)

    //展示用戶信息
    @RequestMapping("/show.action")
    public ModelAndView show(Model model)

    //管理員修改用戶的信息
    @RequestMapping("/toEdit/{id}")
    public ModelAndView toEdit(@PathVariable("id")Long id,Model model)

    //將修改的用戶信息重新存儲到數據庫中
    @RequestMapping("/edit.action")
    public ModelAndView Edit(User user)

1、用戶注冊功能

　　注冊表單：用戶點擊注冊后發送請求到"@{~/register.action}"

<form action="" th:action="@{~/register.action}">
                <div id="form_container2" style="padding-top: 25px;">

                    <input type="text" class="form-control" value="Gary" placeholder="用戶名" id="regist_account" name="username" />
                    <input type="password" class="form-control" placeholder="密碼" id="regist_password1" name="password" />
                    <input type="password" class="form-control" placeholder="確認密碼" id="regist_password2" />
                    <input type="text" class="form-control" placeholder="手機號" id="regist_phone" name="telephone" />
                    <input type="text" class="form-control" placeholder="驗證碼" id="regist_vcode" />
                    <!--<button id="getVCode" type="button" class="btn btn-success" >獲取驗證碼</button>-->
                    <input id="getVCode" type="button" class="btn btn-success" value="點擊發送驗證碼" onclick="sendCode(this)" />

                </div>
                <input type="submit" value="注冊" class="btn btn-success" id="regist_btn" />
            </form>

　　用戶提交表單后，請求提交到controller層去接收"@{~/register.action}"請求

    @RequestMapping("/register.action")
    public ModelAndView register(User user) {
        userServiceImpl.save(user);
        return new ModelAndView("redirect:/");
    }

　　controller層接收到請求后由service去調用save()方法

    @Autowired
    private UserRepository userRepository;
    
    
    @Override
    public void save(User user) {
        userRepository.save(user);    
    }

　　service層去調用repository層save()方法

　　save()方法由CrudRepository()接口自動封裝好(本身提供增刪改查功能)

2、用戶登錄功能

　　登錄表單：用戶點擊登錄后發送請求到"@{~/register.action}"

    <form action="" th:action="@{~/register.action}">
                <div id="form_container2" style="padding-top: 25px;">

                    <input type="text" class="form-control" value="Gary" placeholder="用戶名" id="regist_account" name="username" />
                    <input type="password" class="form-control" placeholder="密碼" id="regist_password1" name="password" />
                    <input type="password" class="form-control" placeholder="確認密碼" id="regist_password2" />
                    <input type="text" class="form-control" placeholder="手機號" id="regist_phone" name="telephone" />
                    <input type="text" class="form-control" placeholder="驗證碼" id="regist_vcode" />
                    <!--<button id="getVCode" type="button" class="btn btn-success" >獲取驗證碼</button>-->
                    <input id="getVCode" type="button" class="btn btn-success" value="點擊發送驗證碼" onclick="sendCode(this)" />

                </div>
                <input type="submit" value="注冊" class="btn btn-success" id="regist_btn" />
            </form>

　　Controller層處理用戶的登錄邏輯，判斷用戶輸入賬號密碼是否正確，輸入正確則跳轉到welcome.html頁面，否則重定向到index.html頁面

    @RequestMapping("/login.action")
    public ModelAndView login(User user) {
        boolean success = userServiceImpl.login(user);
        if(success) {
            return new ModelAndView("/welcome.html");
        }else {
            return new ModelAndView("redirect:/");
        }
    }

　　controller層接收到請求后由service去調用login()方法

    @Override
    public boolean login(User user) {
        User loginUser = userRepository.findByUsernameAndPassword(user.getUsername(),user.getPassword());
        
        return loginUser==null?false:true;
    }

　　service層去調用repository層findByUsernameAndPassword()方法,findByUsernameAndPassword()方法繼承CrudRepository()接口

ublic interface UserRepository extends CrudRepository<User,Long>{

    User findByUsernameAndPassword(String username, String password);

}

3、管理員查詢用戶界面功能

　　管理員想要查看數據庫中的信息得去發送show.action請求，userList得到數據庫中用戶的信息后跳轉至show-all-user.html頁面

    @RequestMapping("/show.action")
    public ModelAndView show(Model model) {
        
        List<User> userList = userServiceImpl.findAll();
        //把userList放入到模型中
        model.addAttribute("userList",userList);
        return new ModelAndView("/show-all-user.html","userModel",model);
    }

    <table border="1px">
        <tr>
            <th>用戶名</th>
            <th>密碼</th>
            <th>電話</th>
            <th>編輯</th>
        </tr>

        <tr th:each="user : ${userList}">
            <th th:text="${user.username}">132</th>
            <th th:text="${user.password}">123</th>
            <th th:text="${user.telephone}">123</th>
            <th>
                <a th:href="@{'~/toEdit/'+${user.id}}">修改</a>
            </th>
        </tr>

4、用戶信息回顯功能

　　controller層接收管理員toEdit請求

@RequestMapping("/toEdit/{id}")
    public ModelAndView toEdit(@PathVariable("id")Long id,Model model) {
        //根據ID得到用戶
        User user = userServiceImpl.findById(id);
        //將用戶放入到model中
        model.addAttribute("user",user);
        return new ModelAndView("/edit-user.html","userModel",model);
    }

　　Optional 用來作為用戶存儲的容器　　傳送門

    @Override
    public List<User> findAll() {
        Iterable<User> list = userRepository.findAll();
        return (List<User>)list;
    }

    @Override
    public User findById(Long id) {
         Optional<User> user = userRepository.findById(id);
        return user.get();
    }

5、管理員修改用戶信息功能

　　controller層去修改用戶信息並重新刷新數據庫中User信息

    @RequestMapping("/edit.action")
    public ModelAndView Edit(User user) {
        userServiceImpl.save(user);
        return new ModelAndView("redirect:/show.action");
    }

　　edit-user.html去修改用戶頁面信息

<form action="" th:action="@{~/edit.action}" method="post">
        
        <input name="id" type="hidden" th:value="${user.id}">
        用戶名：
        <input name="username" type="text" th:value="${user.username}">
        密碼：
        <input name="password" type="text" th:value="${user.password}">
        電話：
        <input name="telephone" type="text" th:value="${user.telephone}">
        
        <input type="submit" value="提交">
        
    </form>
