我试图在我自己的代码中实现这里的代码。但我得到以下错误：

Field confirmationTokenRepository in com.main.mytest.controllers.LoginController required a bean of type 'com.main.mytest.repository.ConfirmationTokenRepository' that could not be found.

Action:

Consider defining a bean of type 'com.main.mytest.repository.ConfirmationTokenRepository' in your configuration.

以下是我的项目结构：

我在类中的代码与链接中提到的完全相同。为了简单起见，我把它们复制到这里：
确认令牌存储库：

package com.main.mytest.repository;

import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;

import com.main.mytest.model.ConfirmationToken;

public interface ConfirmationTokenRepository extends CrudRepository<ConfirmationToken, String> {
    ConfirmationToken findByConfirmationToken(String confirmationToken);
}

确认令牌：

package com.main.mytest.model;    

import java.util.Date;
import java.util.UUID;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.OneToOne;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;

@Entity
public class ConfirmationToken {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name="token_id")
    private long tokenid;

    @Column(name="confirmation_token")
    private String confirmationToken;

    @Temporal(TemporalType.TIMESTAMP)
    private Date createdDate;

    @OneToOne(targetEntity = User.class, fetch = FetchType.EAGER)
    @JoinColumn(nullable = false, name = "user_id")
    private User user;

    public ConfirmationToken() {
    }

    public ConfirmationToken(User user) {
        this.user = user;
        createdDate = new Date();
        confirmationToken = UUID.randomUUID().toString();
    }

    public String getConfirmationToken() {
        return confirmationToken;
    }

    public void setConfirmationToken(String confirmationToken) {
        this.confirmationToken = confirmationToken;
    }

    public Date getCreatedDate() {
        return createdDate;
    }

    public void setCreatedDate(Date createdDate) {
        this.createdDate = createdDate;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

    public long getTokenid() {
        return tokenid;
    }

    public void setTokenid(long tokenid) {
        this.tokenid = tokenid;
    }
}

登录控制器：

@Controller
public class LoginController {

@Autowired
private CustomUserDetailsService userService;

@Autowired
ReviewMongoRepository reviewRepository;

@Autowired
ProfileRepository profileRepository;

@Autowired
private UserRepository userRepository;

@Autowired
private ConfirmationTokenRepository confirmationTokenRepository;

@Autowired
private EmailSenderService emailSenderService;

BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();

@RequestMapping(value="/forgot-password", method=RequestMethod.POST)
public ModelAndView forgotUserPassword(ModelAndView modelAndView, User user) {
    User existingUser = userRepository.findByEmail(user.getEmail());
    if(existingUser != null) {
        // create token
        ConfirmationToken confirmationToken = new ConfirmationToken(existingUser);

        // save it
        confirmationTokenRepository.save(confirmationToken);

        // create the email
        SimpleMailMessage mailMessage = new SimpleMailMessage();
        mailMessage.setTo(existingUser.getEmail());
        mailMessage.setSubject("Complete Password Reset!");
        mailMessage.setFrom("nairobley@gmail.com");
        mailMessage.setText("To complete the password reset process, please click here: "
        +"http://localhost:8082/confirm-reset?token="+confirmationToken.getConfirmationToken());

        emailSenderService.sendEmail(mailMessage);

        modelAndView.addObject("message", "Request to reset password received. Check your inbox for the reset link.");
        modelAndView.setViewName("successForgotPassword");

    } else {    
        modelAndView.addObject("message", "This email does not exist!");
        modelAndView.setViewName("error");
    }

    return modelAndView;
}

@RequestMapping(value="/confirm-reset", method= {RequestMethod.GET, RequestMethod.POST})
public ModelAndView validateResetToken(ModelAndView modelAndView, @RequestParam("token")String confirmationToken)
{
    ConfirmationToken token = confirmationTokenRepository.findByConfirmationToken(confirmationToken);

    if(token != null) {
        User user = userRepository.findByEmail(token.getUser().getEmail());
        user.setEnabled(true);
        userRepository.save(user);
        modelAndView.addObject("user", user);
        modelAndView.addObject("emailId", user.getEmail());
        modelAndView.setViewName("resetPassword");
    } else {
        modelAndView.addObject("message", "The link is invalid or broken!");
        modelAndView.setViewName("error");
    }

    return modelAndView;
}   

/**
 * Receive the token from the link sent via email and display form to reset password
 */
@RequestMapping(value = "/reset-password", method = RequestMethod.POST)
public ModelAndView resetUserPassword(ModelAndView modelAndView, User user) {
    // ConfirmationToken token = confirmationTokenRepository.findByConfirmationToken(confirmationToken);

    if(user.getEmail() != null) {
        // use email to find user
        User tokenUser = userRepository.findByEmail(user.getEmail());
        tokenUser.setEnabled(true);
        tokenUser.setPassword(encoder.encode(user.getPassword()));
        // System.out.println(tokenUser.getPassword());
        userRepository.save(tokenUser);
        modelAndView.addObject("message", "Password successfully reset. You can now log in with the new credentials.");
        modelAndView.setViewName("successResetPassword");
    } else {
        modelAndView.addObject("message","The link is invalid or broken!");
        modelAndView.setViewName("error");
    }

    return modelAndView;
}

public UserRepository getUserRepository() {
    return userRepository;
}

public void setUserRepository(UserRepository userRepository) {
    this.userRepository = userRepository;
}

public ConfirmationTokenRepository getConfirmationTokenRepository() {
    return confirmationTokenRepository;
}

public void setConfirmationTokenRepository(ConfirmationTokenRepository confirmationTokenRepository) {
    this.confirmationTokenRepository = confirmationTokenRepository;
}

public EmailSenderService getEmailSenderService() {
    return emailSenderService;
}

public void setEmailSenderService(EmailSenderService emailSenderService) {
    this.emailSenderService = emailSenderService;
}
}

我已经尝试添加 @Repository 或者 @Service 在我的课堂上，我在stackoverflow上看到过类似的问题，但没有帮助。
更新1：
以下是主应用程序文件：

package com.main.mytest;

import org.springframework.boot.SpringApplication;
    @SpringBootApplication
    @EnableMongoRepositories("com.main.mytest.repository")
    @ComponentScan(basePackages = {"com.main.mytest"}) // added to solve the porblem but didn't help
    @EntityScan("com.main.mytest.model") // added to solve the porblem but didn't help
public class mainClass{

public static void main(String[] args) {
    SpringApplication.run(mainClass.class, args);
        }

public void run() {
}

@Bean
CommandLineRunner init(RoleRepository roleRepository) {

    return args -> {

        Role adminRole = roleRepository.findByRole("ADMIN");
        if (adminRole == null) {
            Role newAdminRole = new Role();
            newAdminRole.setRole("ADMIN");
            roleRepository.save(newAdminRole);
        }

        Role userRole = roleRepository.findByRole("USER");
        if (userRole == null) {
            Role newUserRole = new Role();
            newUserRole.setRole("USER");
            roleRepository.save(newUserRole);
        }
    };

}

}
以下是配置文件：

@Override
protected void configure(HttpSecurity http) throws Exception {

  http
  .authorizeRequests()
  .antMatchers("/confirm").permitAll()
  .antMatchers("/").permitAll()
  .antMatchers("/login").permitAll()
  .antMatchers("/signup").permitAll()

1-添加@repository
2-看看你的@componentscan。如果您的配置文件在另一个文件夹中，而不是在根包下，那么它将找不到组件。
