问题描述
我正在开发Java Spring Boot Web App，目前正在使用的功能是为用户提供的“重置密码”功能。它类似于我已经成功创建的功能，即“注册用户”功能。但是，由于某些我不知道的原因，由于电子邮件验证令牌为空，“注册用户”功能正在运行，但“重置密码”功能却不起作用。首先是用于注册用户的相关控制器：
@RequestMapping(value="/register",method=RequestMethod.GET)
ModelAndView register(ModelAndView modelAndView) throws FileNotFoundException {
SiteUser user = new SiteUser();
modelAndView.getModel().put("user",user);
modelAndView.setViewName("app.register");
return modelAndView;
}
@RequestMapping(value="/register",method=RequestMethod.POST)
ModelAndView register(ModelAndView modelAndView,@ModelAttribute(value="user") @Valid SiteUser user,BindingResult result) {
modelAndView.setViewName("app.register");
if(!result.hasErrors()) {
userService.register(user);
String token = userService.createEmailVerificationTokenRegister(user).toString();
emailService.sendVerificationEmailRegister(user.getEmail(),token);
modelAndView.setViewName("redirect:/verifyEmail");
}
return modelAndView;
}
@RequestMapping("/confirmRegister")
ModelAndView registrationConfirmed(ModelAndView modelAndView,@RequestParam("t") String tokenString) {
VerificationToken token = userService.getVerificationToken(tokenString);
System.out.println("verification token " + token);
if(token == null) {
modelAndView.setViewName("redirect:/invalidUser");
userService.deleteToken(token);
return modelAndView;
}
Date expiryDate = token.getExpiryDate();
if(expiryDate.before(new Date())) {
modelAndView.setViewName("redirect:/expiredToken");
userService.deleteToken(token);
return modelAndView;
}
SiteUser user = token.getUser();
if (user == null) {
modelAndView.setViewName("redirect:/invalidUser");
userService.deleteToken(token);
return modelAndView;
}
userService.deleteToken(token);
user.setEnabled(true);
userService.save(user);
modelAndView.getModel().put("message",registrationConfirmedMessage);
modelAndView.setViewName("app.message");
return modelAndView;
}
请注意，我也将“令牌”打印到System.out，在这种情况下，我得到了一个值，并且此方法成功运行。接下来，我尝试使用几乎相同的方法来实现“重置密码”功能。这是控制器：
@RequestMapping(value="/forgotPassword",method=RequestMethod.GET)
ModelAndView displayResetPassword(ModelAndView modelAndView,SiteUser user) {
modelAndView.getModel().put("user",user);
//modelAndView.addObject("user",user);
modelAndView.setViewName("app.forgotPassword");
//System.out.println("*********** GET **********");
return modelAndView;
}
@RequestMapping(value="/forgotPassword",method=RequestMethod.POST)
ModelAndView forgotUserPassword(ModelAndView modelAndView,@ModelAttribute(value="user") SiteUser user) {
SiteUser existingUser = userRepo.findByEmail(user.getEmail());
//System.out.println(user.getEmail());
//userEmail=existingUser.getEmail();
//userPW=existingUser.getPassword();
//System.out.println(userEmail);
//System.out.println(userPW);
System.out.println(existingUser.getEmail());
if (existingUser.getEmail() == null)
{
modelAndView.setViewName("redirect:/invalidUser");
System.out.println("&&&&&&&&&&&&&&&&&&&&&&&&& if");
}
else {
System.out.println("&&&&&&&&&&&&&&&&&&&&&&&&& else");
String token = userService.createEmailVerificationTokenForgotPassword(existingUser).toString();
emailService.sendVerificationEmailForgotPassword(existingUser.getEmail(),token);
modelAndView.setViewName("redirect:/verifyEmail");
}
return modelAndView;
}
@RequestMapping("/confirmReset")
ModelAndView confirmReset(ModelAndView modelAndView,@RequestParam("t") String tokenString) {
System.out.println("here");
VerificationToken token = userService.getVerificationToken(tokenString);
System.out.println("verification token " + token);
System.out.println("not here");
if(token == null) {
modelAndView.setViewName("redirect:/invalidUser");
userService.deleteToken(token);
System.out.println("*************** ONE ************");
return modelAndView;
}
Date expiryDate = token.getExpiryDate();
if(expiryDate.before(new Date())) {
modelAndView.setViewName("redirect:/expiredToken");
userService.deleteToken(token);
System.out.println("*************** TWO ************");
return modelAndView;
}
SiteUser user = token.getUser();
System.out.println("************ USER IS HERE: " + user);
if (user == null) {
modelAndView.setViewName("redirect:/invalidUser");
userService.deleteToken(token);
System.out.println("*************** THREE ************");
return modelAndView;
}
user.setEnabled(true);
userRepo.save(user);
modelAndView.addObject("user",user);
modelAndView.addObject("email",user.getEmail());
modelAndView.setViewName("redirect:/resetPassword");
userService.deleteToken(token);
return modelAndView;
}
当我尝试将'token'打印到System.out时，这里的区别是该值为null。我不知道怎么回事，因此我无法重置密码。
出于良好的考虑，这也是VerificationToken类变量，未显示getter / setter：
@Entity
@Table(name="Verification")
public class VerificationToken {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="id")
private Long id;
@Column(name="token")
private String token;
@OneToOne(targetEntity=SiteUser.class) // for every user,there's 1 verification token
@JoinColumn(name="user_id",nullable=false) // foreign key to users table
private SiteUser user;
@Column(name="expiry_date")
@Temporal(TemporalType.TIMESTAMP)
private Date expiryDate;
@Column(name="token_type")
@Enumerated(EnumType.STRING)
private TokenType tokenType;
...
}
以及发送到用户电子邮件的实际电子邮件.html文件。首先，forgotPassword.html，它当然不起作用：
<!DOCTYPE html>
<html>
<th:block xmlns:th="http://www.thymeleaf.org">
<p>Please click <a th:href="@{${url} + '/confirmReset?t=' + ${token}}">here</a> to verify your email address and reset your password.</p>
<!-- @{} is a thymeleaf expression -->
</th:block>
</html>
然后是verifyEmail.html，它当然是用于注册新用户的
<!DOCTYPE html>
<html>
<th:block xmlns:th="http://www.thymeleaf.org">
<p>Thank you for registering for the bcoreHW site!</p>
<p>Please click <a th:href="@{${url} + '/confirmRegister?t=' + ${token}}">here</a> to verify your email address.</p>
<!-- @{} is a thymeleaf expression -->
</th:block>
</html>
最后，这是堆栈跟踪的相关部分。请注意System.out.println（）语句以及所显示的内容与未显示的内容：
