Spring MVC를 사용하여 응용 프로그램을 작성하고 있습니다. 사용자가 등록 할 때 데이터베이스에 전자 메일이 있는지 확인하려고합니다. 나는 UniqueEmail이라는 내 자신의 주석 제한을 작성했습니다.ConstraintValidator에서 서비스를 autowire하는 방법
내 사용자 개체 User.java :
@Entity
@Table(name="users")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
@Column(name = "email", length = 100, nullable = false, unique = true)
@NotEmpty
@Email
@UniqueEmail(message = "E-mail is not unique")
private String email;
@Column(name = "password", nullable = false)
@NotEmpty
@Size(min = 5, message = "size must be more 5")
private String password;
}
내 주석 제약 UniqueEmail.java :
@Target({FIELD})
@Retention(RUNTIME)
@Constraint(validatedBy = UniqueEmailValidator.class)
@Documented
public @interface UniqueEmail {
String message() default "Email is exist";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}
내 검증 UniqueEmailValidator.java :
@Component
public class UniqueEmailValidator implements ConstraintValidator<UniqueEmail, String> {
@Autowired
private UserService userService;
@Override
public void initialize(UniqueEmail uniqueEmail) {
}
@Override
public boolean isValid(String s, ConstraintValidatorContext constraintValidatorContext) {
try {
return userService.isExistEmail(s);
} catch (Exception e) {
System.out.println(e);
return false;
}
}
}
이 코드는 응용 프로그램에서 작동합니다.
테스트 코드를 실행하면 해당 NullPointerException이 반환됩니다. 유효성 검사 클래스에서 userService이 null입니다.
나는 http://docs.spring.io/spring/docs/3.0.0.RC3/reference/html/ch05s07.html을 읽었지만 어떤 해결책도 없습니다.
아이디어가 있으십니까?
업데이트 내가 JUnit을 사용합니다. UserClassTest.java
@ContextConfiguration("file:src/main/webapp/WEB-INF/mvc-dispatcher-servlet.xml")
public class UserClass {
private static Validator validator;
@BeforeClass
public static void setup() {
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
validator = factory.getValidator();
}
@Test
public void emailIsUnique() {
User user = new User();
user.setEmail("[email protected]"); // I've written exist email in DB.
Set<ConstraintViolation<User>> constraintViolations = validator.validateProperty(user, "email");
assertEquals(1, constraintViolations.size());
assertEquals("E-mail is not unique", constraintViolations.iterator().next().getMessage());
}
}

, 당신이 제대로 autowire가 필요가 없습니다. – Eugene
