rawPassword 不能为 null 异常

Question

我有以下问题：

我想测试用户是否注册成功。我不是通过 UI 而是通过 Postman 执行此操作。问题是当我使用 POST 命令时出现异常。我已经检查了所有注释。

例外：

java.lang.IllegalArgumentException： org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder.encode(BCryptPasswordEncoder.java:103) ~[spring-security-core-5.3.3.RELEASE.jar:5.3.3 rawPassword 不能为空.RELEASE] 在 com.example.application.backend.data.service.UserService.singUpUser(UserService.java:41) ~[classes/:na] 在 com.example.application.backend.data.registration.RegistrationService.register( RegistrationService.java:22) ~[classes/:na] 位于 com.example.application.backend.data.registration.RegistrationController.register(RegistrationController.java:18)

这是我的 UserService 类：

private final static  String USER_NOT_FOUND_MSG = "user with email %s not found";
@Autowired
private final UserRepository userRepository;
@Autowired
private final BCryptPasswordEncoder bCryptPasswordEncoder;

public UserService(
        UserRepository userRepository,
        BCryptPasswordEncoder bCryptPasswordEncoder) {
    this.userRepository = userRepository;
    this.bCryptPasswordEncoder = bCryptPasswordEncoder;
}

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

public String singUpUser(User user) {
    boolean userExists = userRepository.findByEmail(user.getEmail()).isPresent();

    if(userExists){
        throw new IllegalStateException("email already taken");
    }

    String encodedPassword = bCryptPasswordEncoder.encode(user.getPassword());

    user.setPassword(encodedPassword);

    userRepository.save(user);

    return "it works";
}

注册服务类别：

@Autowired
private final UserService userService;
private final EmailValidator emailValidator;

public String register(RegistrationRequest request) {
    boolean isValidEmail = emailValidator.test(request.getEmail());
    if (!isValidEmail) {
        throw new IllegalStateException("email not valid");
    }
    return userService.singUpUser(
            new User(
                    request.getFirstName(),
                    request.getLastName(),
                    request.getEmail(),
                    request.getPassword(),
                    UserRole.USER
            )
    );
}

public RegistrationService(UserService userService, EmailValidator emailValidator) {
    this.userService = userService;
    this.emailValidator = emailValidator;
}

注册控制器类：

@Autowired
private RegistrationService registrationService;

@PostMapping
public String register(@RequestBody RegistrationRequest request) {
    return registrationService.register(request);
}

Answer 1

当提供给 bCryptEncoder 的密码字符串为空或 null 时，会发生此错误。

在您的 UserService.java 类中，

String encodedPassword = bCryptPasswordEncoder.encode(user.getPassword());

user.getPassword() 为 null，这意味着在 RegistrationService.java 类中，

request.getPassword()

正在获取空值。

请检查您是否从请求对象中获取了正确的密码参数名称。如果可能，请在代码中添加一些记录器语句并进行调试。
