努力在春天創造豆子
[英]struggling with creating beans in spring
問題描述
我正在研究注冊安全。
@RestController
public class UserController {
@Autowired
private BCryptPasswordEncoder bCryptPasswordEncoder;
private UserService userService;
private EmailService emailService;
@Autowired
public UserController(BCryptPasswordEncoder bCryptPasswordEncoder,
UserService userService, EmailService emailService) {
this.bCryptPasswordEncoder = bCryptPasswordEncoder;
this.userService = userService;
this.emailService = emailService;
}
// Return registration form template
@RequestMapping(value="/register", method = RequestMethod.GET)
public ModelAndView showRegistrationPage(ModelAndView modelAndView, User user){
modelAndView.addObject("user", user);
modelAndView.setViewName("register");
return modelAndView;
}
// Process form input data
@RequestMapping(value = "/register", method = RequestMethod.POST)
public ModelAndView processRegistrationForm(ModelAndView modelAndView, @Valid User user, BindingResult bindingResult, HttpServletRequest request) {
// Lookup user in database by e-mail
User userExists = userService.findByEmail(user.getEmail());
System.out.println(userExists);
if (userExists != null) {
modelAndView.addObject("alreadyRegisteredMessage", "Oops! There is already a user registered with the email provided.");
modelAndView.setViewName("register");
bindingResult.reject("email");
}
if (bindingResult.hasErrors()) {
modelAndView.setViewName("register");
} else { // new user so we create user and send confirmation e-mail
// Disable user until they click on confirmation link in email
user.setEnabled(false);
// Generate random 36-character string token for confirmation link
user.setConfirmationTekn(UUID.randomUUID().toString());
userService.saveUser(user);
String appUrl = request.getScheme() + "://" + request.getServerName();
SimpleMailMessage registrationEmail = new SimpleMailMessage();
registrationEmail.setTo(user.getEmail());
registrationEmail.setSubject("Registration Confirmation");
registrationEmail.setText("To confirm your e-mail address, please click the link below:\n"
+ appUrl + "/confirm?token=" + user.getConfirmationTekn());
registrationEmail.setFrom("noreply@domain.com");
emailService.sendEmail(registrationEmail);
modelAndView.addObject("confirmationMessage", "A confirmation e-mail has been sent to " + user.getEmail());
modelAndView.setViewName("register");
}
return modelAndView;
}
// Process confirmation link
@RequestMapping(value="/confirm", method = RequestMethod.GET)
public ModelAndView confirmRegistration(ModelAndView modelAndView,
@RequestParam("token") String token) {
User user = userService.findByConfirmationToken(token);
if (user == null) { // No token found in DB
modelAndView.addObject("invalidToken", "Oops! This is an invalid confirmation link.");
} else { // Token found
modelAndView.addObject("confirmationToken", user.getConfirmationTekn());
}
modelAndView.setViewName("confirm");
return modelAndView;
}
// Process confirmation link
@RequestMapping(value="/confirm", method = RequestMethod.POST)
public ModelAndView confirmRegistration(ModelAndView modelAndView, BindingResult bindingResult, @RequestParam Map<String, String> requestParams, RedirectAttributes redir) {
modelAndView.setViewName("confirm");
Zxcvbn passwordCheck = new Zxcvbn();
Strength strength = passwordCheck.measure(requestParams.get("password"));
if (strength.getScore() < 3) {
//modelAndView.addObject("errorMessage", "Your password is too weak. Choose a stronger one.");
bindingResult.reject("password");
redir.addFlashAttribute("errorMessage", "Your password is too weak. Choose a stronger one.");
modelAndView.setViewName("redirect:confirm?token=" + requestParams.get("token"));
System.out.println(requestParams.get("token"));
return modelAndView;
}
// Find the user associated with the reset token
User user = userService.findByConfirmationToken(requestParams.get("token"));
// Set new password
user.setPassword(bCryptPasswordEncoder.encode(requestParams.get("password")));
// Set user to enabled
user.setEnabled(true);
// Save user
userService.saveUser(user);
modelAndView.addObject("successMessage", "Your password has been set!");
return modelAndView;
}
}
和我的MyWebMvc
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
@Bean
public BCryptPasswordEncoder passwordEncoder() {
BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
return encoder;
}
}
和UserService
@Service("userService")
public class UserService {
private UserRepository userRepository;
@Autowired
public UserService(UserRepository userRepository) {
this.userRepository = userRepository;
}
public UserService() {
}
public User findByEmail(String email) {
return userRepository.findByEmail(email);
}
public void saveUser(User user) {
userRepository.save(user);
}
public User findByConfirmationToken(String token) {
return userRepository.findByTokenConfirmation(token);
}
}
而堆棧跟蹤是這樣的：
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userController' defined in file [C:\Users\HP\Downloads\Point1\Point1\target\classes\com\point\application\Point1\controller\UserController.class]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userService' defined in file [C:\Users\HP\Downloads\Point1\Point1\target\classes\com\point\application\Point1\service\UserService.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Failed to create query for method public abstract com.point.application.Point1.modal.User com.point.application.Point1.repository.UserRepository.findByTokenConfirmation(java.lang.String)!

3 個解決方案
解決方案1
3 2018-10-19 12:07:12
看起來User類缺少屬性tokenConfirmation：
“無法為方法公共抽象com.point.application.Point1.modal.User com.point.application.Point1.repository.UserRepository.findByTokenConfirmation（java.lang.String）創建查詢！ 找不到類型為User ！的屬性tokenConfirmation 。
或者可能不丟失但拼寫錯誤（tokenConfirmation或confirmationToken）：
public User findByConfirmationToken(String token) {
return userRepository.findByTokenConfirmation(token);
}
解決方案2

它基於Java的配置，因此Your MyWebMvc配置類也需要具有UserService bean的bean定義。
@Bean
public UserService userService(){
return new UserService();
}
解決方案3
0 2018-10-22 08:50:46
@雅各布·戈多努克（Jakub Godoniuk ..）
@Service（“ userService”）公共類UserService {
private UserRepository userRepository;
@Autowired
public UserService(UserRepository userRepository) {
this.userRepository = userRepository;
}
public UserService() {
}
public User findByEmail(String email) {
return userRepository.findByEmail(email);
}
public void saveUser(User user) {
userRepository.save(user);
}
public User findByConfirmationToken(String confirmationToken) {
return userRepository.findByTokenConfirmation(confirmationToken);
}
}
下面是存儲庫
@Repository("userRepository")
公共接口UserRepository擴展了CrudRepository {
User findByEmail(String email);
User findByTokenConfirmation(String confirmationToken);
}
和我的實體
@Entity
@Table（name =“ user_table”）公共類User {
@Id
@GeneratedValue
private long id;
@Column(name = "email")
@Email
@NotNull(message = "please enter a valid email")
private String email;
private String password;
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public User(long id, @Email @NotNull(message = "please enter a valid email") String email,
@NotNull(message = "please enter your first name") String firstname,
@NotNull(message = "please enter you last_name") String lastname, boolean enabled, String password,
String confirmationToken) {
this.id = id;
this.email = email;
this.firstname = firstname;
this.lastname = lastname;
this.enabled = enabled;
this.confirmationToken = confirmationToken;
this.password = password;
}
public User() {
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public boolean isEnabled() {
return enabled;
}
public void setEnabled(boolean enabled) {
this.enabled = enabled;
}
public String getConfirmationToken() {
return confirmationToken;
}
public void setConfirmationTekn(String confirmationTekn) {
this.confirmationToken = confirmationTekn;
}
@Column(name = "first_name")
@NotNull(message = "please enter your first name")
private String firstname;
@Column(name = "last_name")
@NotNull(message = "please enter you last_name")
private String lastname;
@Column(name = "enabled")
private boolean enabled;
private String confirmationToken;
}
而且我仍然得到這個異常：
創建文件[C：\\ Users \\ HP \\ Downloads \\ Point1 \\ Point1 \\ target \\ classes \\ com \\ point \\ application \\ Point1 \\ controller \\ UserController.class]中定義的名稱為'userController'的bean時出錯：通過構造函數參數表示的不滿意依賴關系1; 嵌套的異常是org.springframework.beans.factory.UnsatisfiedDependencyException：創建名稱為“ userService”的bean時出錯，該文件在文件[C：\\ Users \\ HP \\ Downloads \\ Point1 \\ Point1 \\ target \\ classes \\ com \\ point \\ application \\ Point1 \\中定義[service \\ UserService.class]：通過構造函數參數0表示的不滿足的依賴關系； 嵌套的異常是org.springframework.beans.factory.BeanCreationException：創建名稱為'userRepository'的bean時出錯：調用init方法失敗； 嵌套異常是java.lang.IllegalArgumentException：無法為方法公共抽象com.point.application.Point1.modal.User com.point.application.Point1.repository.UserRepository.findByTokenConfirmation（java.lang.String）創建查詢！ 找不到用戶類型的屬性tokenConfirmation！
