使用Gradle编译项目 传送门
项目已托管到Github上 传送门
SpringBoot使用MySQL实现
实现功能：普通用户注册、普通用户登录、管理员通过edit-user页面和show-all-user页面对用户信息的修改

实现过程分五步
1、用户注册功能
2、用户登录功能
3、管理员查询用户界面功能
4、用户信息回显功能
5、管理员修改用户信息功能
2、用户登录功能
3、管理员查询用户界面功能
4、用户信息回显功能
5、管理员修改用户信息功能
controller控制层
service业务逻辑层
repository持久层
User实体 设置主键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层获接收用户和管理员请求并做相应的回应
//访问首页面
@RequestMapping("/")
public ModelAndView index() //用户注册
@RequestMapping("/register.action")
public ModelAndView register(User user) //用户登录
@RequestMapping("/login.action")
public ModelAndView login(User user) //展示用户信息
@RequestMapping("/show.action")
public ModelAndView show(Model model) //管理员修改用户的信息
@RequestMapping("/toEdit/{id}")
public ModelAndView toEdit(@PathVariable("id")Long id,Model model) //将修改的用户信息重新存储到数据库中
@RequestMapping("/edit.action")
public ModelAndView Edit(User user)
1、用户注册功能
注册表单：用户点击注册后发送请求到"@{~/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="用户名" id="regist_account" name="username" />
<input type="password" class="form-control" placeholder="密码" id="regist_password1" name="password" />
<input type="password" class="form-control" placeholder="确认密码" id="regist_password2" />
<input type="text" class="form-control" placeholder="手机号" id="regist_phone" name="telephone" />
<input type="text" class="form-control" placeholder="验证码" id="regist_vcode" />
<!--<button id="getVCode" type="button" class="btn btn-success" >获取验证码</button>-->
<input id="getVCode" type="button" class="btn btn-success" value="点击发送验证码" onclick="sendCode(this)" />
</div>
<input type="submit" value="注册" class="btn btn-success" id="regist_btn" />
</form>
用户提交表单后，请求提交到controller层去接收"@{~/register.action}"请求
@RequestMapping("/register.action")
public ModelAndView register(User user) {
userServiceImpl.save(user);
return new ModelAndView("redirect:/");
}
controller层接收到请求后由service去调用save()方法
@Autowired
private UserRepository userRepository; @Override
public void save(User user) {
userRepository.save(user);
}
service层去调用repository层save()方法
save()方法由CrudRepository()接口自动封装好(本身提供增删改查功能)
2、用户登录功能
登录表单：用户点击登录后发送请求到"@{~/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="用户名" id="regist_account" name="username" />
<input type="password" class="form-control" placeholder="密码" id="regist_password1" name="password" />
<input type="password" class="form-control" placeholder="确认密码" id="regist_password2" />
<input type="text" class="form-control" placeholder="手机号" id="regist_phone" name="telephone" />
<input type="text" class="form-control" placeholder="验证码" id="regist_vcode" />
<!--<button id="getVCode" type="button" class="btn btn-success" >获取验证码</button>-->
<input id="getVCode" type="button" class="btn btn-success" value="点击发送验证码" onclick="sendCode(this)" />
</div>
<input type="submit" value="注册" class="btn btn-success" id="regist_btn" />
</form>
Controller层处理用户的登录逻辑，判断用户输入账号密码是否正确，输入正确则跳转到welcome.html页面，否则重定向到index.html页面
@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层接收到请求后由service去调用login()方法
@Override
public boolean login(User user) {
User loginUser = userRepository.findByUsernameAndPassword(user.getUsername(),user.getPassword()); return loginUser==null?false:true;
}
service层去调用repository层findByUsernameAndPassword()方法,findByUsernameAndPassword()方法继承CrudRepository()接口
ublic interface UserRepository extends CrudRepository<User,Long>{
User findByUsernameAndPassword(String username, String password);
}
3、管理员查询用户界面功能
管理员想要查看数据库中的信息得去发送show.action请求，userList得到数据库中用户的信息后跳转至show-all-user.html页面
@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>用户名</th>
<th>密码</th>
<th>电话</th>
<th>编辑</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/'+${user.id}}">修改</a>
</th>
</tr>
4、用户信息回显功能
controller层接收管理员toEdit请求
@RequestMapping("/toEdit/{id}")
public ModelAndView toEdit(@PathVariable("id")Long id,Model model) {
//根据ID得到用户
User user = userServiceImpl.findById(id);
//将用户放入到model中
model.addAttribute("user",user);
return new ModelAndView("/edit-user.html","userModel",model);
}
Optional 用来作为用户存储的容器 传送门
@Override
public List<User> findAll() {
Iterable<User> list = userRepository.findAll();
return (List<User>)list;
} @Override
public User findById(Long id) {
Optional<User> user = userRepository.findById(id);
return user.get();
}
5、管理员修改用户信息功能
controller层去修改用户信息并重新刷新数据库中User信息
@RequestMapping("/edit.action")
public ModelAndView Edit(User user) {
userServiceImpl.save(user);
return new ModelAndView("redirect:/show.action");
}
edit-user.html去修改用户页面信息
<form action="" th:action="@{~/edit.action}" method="post">
<input name="id" type="hidden" th:value="${user.id}">
用户名：
<input name="username" type="text" th:value="${user.username}">
密码：
<input name="password" type="text" th:value="${user.password}">
电话：
<input name="telephone" type="text" th:value="${user.telephone}">
<input type="submit" value="提交">
</form>
