spring boot自定义验证器注释不适用于参数

@RestController
@Validated
public class UserController {

    @PostMapping("/users")
    public ResponseEntity createUser(@Valid @RequestBody User user) {
        // 处理创建用户的逻辑
        return ResponseEntity.ok("User created successfully");
    }
}

@Target({ElementType.FIELD, ElementType.PARAMETER})
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy = PhoneNumberValidator.class)
public @interface PhoneNumber {

    String message() default "Invalid phone number";

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};
}

public class PhoneNumberValidator implements ConstraintValidator<PhoneNumber, String> {

    @Override
    public void initialize(PhoneNumber constraintAnnotation) {
        // 初始化验证器
    }

    @Override
    public boolean isValid(String value, ConstraintValidatorContext context) {
        // 执行验证逻辑
        // 返回true表示验证通过，返回false表示验证失败
    }
}

public class User {

    @PhoneNumber
    private String phoneNumber;

    // 其他字段和方法
}
