问题描述

嗨，我的简单 Spring 启动安全项目

我的用户控制器

@RestController
@RequestMapping(path= "/api")
@RequiredArgcContructor
public class UserController {

    
    private final UserService userService;

    @PostMapping
    public String create(@RequestBody UserDTO userDto){
        return  userService.save(userDto);
    }

}

我的用户服务

@Service
@RequiredArgsConstructor
public class UserService {

 
    private  UserManager userManager;
    private  Mapper<UserDTO, UserEntity> userDTOUserMapper;

    public String save(UserDTO userDto) {
        return userManager.signUp(userDTOUserMapper.map(userDto));
    }

}

我的用户管理器

   package com.userlogintask.userlogintask.business;

import org.springframework.stereotype.Component;

import java.time.LocalDateTime;
import java.util.UUID;

@Component
@RequiredArgsConstructor
public class UserManager implements UserDetailsService {

    private final static String USER_NOT_FOUND_msg="user with email %s not found";
   
    private final UserRepository userRepository;
    private final BCryptPasswordEncoder bCryptPasswordEncoder;
    private final TokenManager tokenManager;

    @Override
    public UserDetails loadUserByUsername(String email) throws UsernameNotFoundException {
        return userRepository.findByEmail(email)
                .orElseThrow(()-> new UsernameNotFoundException(String.format(USER_NOT_FOUND_msg,email)));
    }


    public String signUp(UserEntity userEntity){
        boolean isExist =  userRepository.findByEmail(userEntity.getEmail()).isPresent();

        if(isExist){
            throw new IllegalStateException("email is already exists");
        }
        String encodePassword = bCryptPasswordEncoder.encode(userEntity.getPassword());
        userEntity.setPassword(encodePassword);
        userRepository.save(userEntity);

        //TODO:Send confirmation token;
        String token = UUID.randomUUID().toString();

        TokenEntity confirmationTokenEntity = new TokenEntity(
                token,
                LocalDateTime.now(),
                LocalDateTime.now().plusMinutes(15),
                userEntity
        );
        tokenManager.saveConfirmationToken(confirmationTokenEntity);

        //TODO:Send email

        return  token;
    }

    public int enableAppUser(String email) {
        return userRepository.enableUser(email);
    }

}

我的映射配置

 @Configuration
public class ApiMappingConfig {

    //userDTO mapping user

    @Bean
    public Mapper<UserDTO, UserEntity> userDTOUserMapper(){
        return Mapping.from(UserDTO.class)
                .to(UserEntity.class)
                .omitInDestination(UserEntity::getLocked)
                .omitInDestination(UserEntity::getUser_id)
                .omitInDestination(UserEntity::getEnabled)
                .mapper();
    }
}

我的用户实体

 @Data
@NoArgsConstructor
@AllArgsConstructor
@Entity
public class UserEntity implements UserDetails {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)

    public UserEntity(String firstName,
                      String lastName, String email,
                      String password, UserRole userRole) {

        this.firstName = firstName;

    @Override

        return Collections.singleton(new SimpleGrantedAuthority(userRole.name()));
    }

    @Override
    public String getPassword() {
        return password;
    }

    @Override
    public String getUsername() {
        return email;

        return true;
    }

    @Override
    public boolean isEnabled() {
        return enabled;
    }

}

我的用户 DTO

  @Data
@NoArgsConstructor
@AllArgsConstructor
public class UserDTO {

    private String firstName;
    private String lastName;
    private String email;
    private String password;
    private UserRole userRole;

}

我的主 Class

 @SpringBootApplication
public class UserlogintaskApplication {

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

}

好的，看起来错误是：

.MappingException: The get-method for property 'enabled' in type com.userlogintask.userlogintask.model.UserEntity is not a valid Java Bean property. at

这就是为什么无法按需要创建映射器的原因，这反过来又会导致服务的BeanInitializationException 。

查看您的实体，您使用： Boolean用于enabled属性，但吸气剂返回boolean （不是包装器 class 而是真正的原语）。 尝试改变它，看看会发生什么。

现在我还没有使用过 Mappers，所以我无法真正评论您在创建映射器时调用的omitInDestination方法的语义。 但是我认为您可以放置一个断点并确保 spring 从您的配置中初始化映射器，这是一种通用的“常识”建议。
