Kotlin Spring Boot验证不起作用

Question

当我使用null email向/注册用户发送一个POST请求时，我希望它会说“Hey，you have null in email field”，但由于user.email！！语句，它会在保存步骤中抛出NPE。当我用错误的电子邮件发送json时，如下所示：

{
  "email": "wrongEmailAddress",
  "username": "username",
  "phoneNumber": "[phone]",
  "password": "234adfg24",
  "role": "USER"
}

它完美地通过了这个约束注释：

@Email
@Pattern(regexp = ".+@.+\\..+", message = "Please provide a valid email address")
@Target(
        AnnotationTarget.FIELD,
        AnnotationTarget.FUNCTION,
        AnnotationTarget.ANNOTATION_CLASS,
        AnnotationTarget.PROPERTY,
        AnnotationTarget.PROPERTY_GETTER)
@Retention(AnnotationRetention.RUNTIME)
@Constraint(validatedBy = [])
@MustBeDocumented
annotation class ValidEmail(
        val message: String = "Please provide a valid email address",
        val groups: Array<KClass<out Any>> = [],
        val payload: Array<KClass<out Payload>> = []
)

@RestController
class UserController(
        @Autowired val userService: UserService) {

    @PostMapping(
            path=["/register"],
            consumes=["application/json"],
            produces=["application/json"])
    fun registerNewUser(
            @Valid @RequestBody user: User): UserDTO {
        user.encryptPassword()
        userService.registerNewUser(user)
        return UserDTO(user)
    }
}

@Entity
class User(
        @get:NotNull @field:ValidEmail @Column(unique = true)
        var email: String? = null,
        @get:NotNull @Column(unique = true)
        var username: String? = null,
        @get:NotNull @field:ValidPhoneNumber @Column(unique = true)
        var phoneNumber: String? = null,
        @get:NotNull @field:ValidPassword
        var password: String? = null,
        @get:NotNull
        var role: Role? = null,

        var address: String? = null
) : BaseEntity()
{
    fun encryptPassword() {
        password = BCryptPasswordEncoder().encode(password)
    }
}

@MappedSuperclass
open class BaseEntity(
        @Id @NotNull @GeneratedValue(generator = "UUID")
        @GenericGenerator(name="UUID", strategy = "org.hibernate.id.UUIDGenerator")
        open val id: UUID? = null)

我试过的。我尝试在@validemail、@get:validemail、@field:validemail(kotlin data class+bean validation JSR303、https://stackoverrun.com/ru/q/9883168和其他来源）之间进行更改，尝试用Java重写所有内容。什么都不管用。PhoneNumberValidator通过所有单元测试，但是约束@ValidPhoneNumber也不起作用。甚至没有一个约束工作。谢谢你的建议。

用@validated标记restcontroller。
