Question

I am working on a registration security .

@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;        
}

}

and my MyWebMvc

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

@Bean
public BCryptPasswordEncoder passwordEncoder() {

    BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();

    return encoder;
}
}

and 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);
}

}

and the stacktrace is like this:

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)!

Answer 1

Looks that there is a property tokenConfirmation missing from User class:

"Failed to create query for method public abstract com.point.application.Point1.modal.User com.point.application.Point1.repository.UserRepository.findByTokenConfirmation(java.lang.String)! No property tokenConfirmation found for type User ! "

Or maybe not missing but rather misspelled (tokenConfirmation or confirmationToken):

public User findByConfirmationToken(String token) {
    return userRepository.findByTokenConfirmation(token);
}

Answer 2

Its Java based configuration so Your MyWebMvc configuration class needs to have bean definition for UserService bean as well.

@Bean
 public UserService userService(){
      return new UserService();
 }

Answer 3

@Jakub Godoniuk .. i did changing the property names like bellow

@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 confirmationToken) {

    return userRepository.findByTokenConfirmation(confirmationToken);
}

}

and below is resipository

@Repository("userRepository")

public interface UserRepository extends CrudRepository{

User findByEmail(String email);

User findByTokenConfirmation(String confirmationToken);

}

and my Entity

@Entity

@Table(name = "user_table") public class 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) {
