【问题描述】：
我在尝试了解如何通过 Spring Boot Hibernate 编辑配置文件时遇到了一些麻烦。请注意，此项目不包括 thymeleaf 或 spring security。
我正在尝试获取已登录的用户并获取他的电子邮件实例，以便能够在名为 editProfile.jsp 的 JSP 中对其进行更新。我的欢迎页面上的 My Profile 链接应该获取登录用户的信息并将您带到 editProfile jsp，用户可以在其中编辑信息和更新信息。 到目前为止，我已经尝试了一些方法，但似乎都没有。
我不断收到此堆栈跟踪
There was an unexpected error (type=Internal Server Error, status=500).

我以为我已经设置好了所有东西，但显然我没有，所以我决定在这里发布我的问题。
这是我的欢迎页面的图片，因此您可以大致了解我在说什么，右上角的“我的个人资料”链接应该将我带到 editProfile.jsp。您还可以看到，我能够成功添加登录用户名并将其从登录控制器输出到欢迎页面
这是welcome.jsp

这是我的登录控制器，看看我如何将数据从登录控制器传递到 welcome.jsp
@RequestMapping(value = "/login", method = RequestMethod.POST)
public Object submitLoginIn(@ModelAttribute("login") AccountEntity accountForm, Model model) {
AccountEntity accountInstance = accountRepo.findByEmail(accountForm.getEmail().toLowerCase());
// Password Verifier using Argon2
Argon2PasswordEncoder argon2PasswordEncoder = new Argon2PasswordEncoder();
boolean passwordMatch = argon2PasswordEncoder.matches(accountForm.getPassword(), accountInstance.getPassword());
// issue where if i use caps email, throws null pointer exception
if (accountInstance == null || !passwordMatch) {
System.out.println("Invalid Email or Password");
// return ResponseEntity.status(HttpStatus.BAD_REQUEST).body(null);
return "login";
} else if (accountInstance.isEnabled() == false) {
System.out.println("Cant login cause not verified");
return "login";
} else {
System.out.println("account exist");
model.addAttribute("firstName", accountInstance);
return "welcome";
}
}
}
这是我的欢迎控制器，这可能是问题所在，但我完全是空白
@Controller
public class WelcomeController {
AccountRepository accountRepo;
@RequestMapping(value = "/welcome", method = RequestMethod.GET)
public String showWelcmPage(Model model) {
return "welcome";
}
@RequestMapping(value = "welcome/edit/{email}", method = RequestMethod.GET)
public String getEditUserData(@PathVariable("email") String email, Model model, AccountEntity accountForm) {
model.addAttribute("accountEmail", email);
return "editProfile";
}
@RequestMapping(value = "editProfile", method = RequestMethod.GET)
public String showEditProfilePage(Model model, AccountEntity accountForm) {
model.addAttribute("email", accountForm.getEmail());
model.addAttribute("password", accountForm.getPassword());
return "editProfile";
}
@RequestMapping(value = "editProfile", method = RequestMethod.POST)
public String sendEditProfilePage(@ModelAttribute("accountForm") AccountEntity accountForm, Model model) {
AccountEntity accountInstance = accountRepo.findByEmail(accountForm.getEmail());
accountInstance.setEmail(accountForm.getEmail());
accountInstance.setPassword(accountForm.getPassword());
accountRepo.save(accountForm);
return "editProfile";
}
// @RequestMapping(value = "editProfile/{email}", method = RequestMethod.GET)
// public String Data(@PathVariable("email") String email, Model model) {
// AccountEntity accountInstance = accountRepo.findByEmail(email);
// model.addAttribute("accountForm", accountInstance);
// return "editProfile";
// }
}
最后但并非最不重要的是我的 AccountEntity
@Entity(name = "user")
public class AccountEntity {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String firstName;
private String lastName;
private String userName;
private String email;
private String password;
// private String gender;
private Integer age;
private Date createdDate;
private boolean enabled;
@Column(updatable = false)
private String verificationCode;
// Getters and Setters
public void setId(Long id) {
this.id = id;
}
public Long getId() {
return id;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
/*
* public String getGender() { return gender; }
*
* public void setGender(String gender) { this.gender = gender; }
*/
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getVerificationCode() {
return verificationCode;
}
public void setVerificationCode(String verificationCode) {
this.verificationCode = verificationCode;
}
public Date getCreatedDate() {
return createdDate;
}
public void setCreatedDate(Date createdDate) {
this.createdDate = createdDate;
}
public boolean isEnabled() {
return enabled;
}
public void setEnabled(boolean enabled) {
this.enabled = enabled;
}
}
