javax.validation.ValidationException: HV000063: Не удалось создать экземпляр класса

Question

Я запускаю junit, написанный в пользовательской JSR 303 Проверка с использованием ConstraintValidator. Что-то вроде этого example

Моего Validation тестового класса:

public class ProductV2ValidationTest { 
    private static Validator validator; 
    @Before 
    public void setUp() throws ExternalApiException { 
     ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory(); 
     validator = validatorFactory.getValidator(); 
    } 

    @Test 
    public void ValidatorTest() { 
     try { 
      ProductV2 productV2 = getObjectMapper().readValue(this.getClass().getResourceAsStream("/json/productV2Valid.json"), ProductV2.class); 

      Set<ConstraintViolation<ProductV2>> constraintViolations = validator.validate(productV2); 
      for(ConstraintViolation<ProductV2> constraintViolation : constraintViolations){ 
      String message = constraintViolation.getMessage(); 
      System.out.println(message); 
     } 

     assertEquals(0,constraintViolations.size()); 

    } catch (IOException e) { 
     e.printStackTrace(); 
     assertTrue(false); 
    } 
} 

}

FYI, Мои валидаторов в какой-то другой специалист проект (банке), и тест написано в другом Maven проекте (война) ,

Я получаю эту ошибку:

Я попытался добавить

<dependency> 
    <groupId>javax.el</groupId> 
    <artifactId>javax.el-api</artifactId> 
    <version>2.2.4</version> 
</dependency> 
<dependency> 
    <groupId>org.glassfish.web</groupId> 
    <artifactId>javax.el</artifactId>

Но никакой помощи.

Я использую это: Зависимость от

<dependency> 
     <groupId>org.hibernate</groupId> 
     <artifactId>hibernate-validator</artifactId> 
     <version>5.0.2.Final</version> 
     <exclusions>

    </dependency> 

Answer 1

Проблема в том, что спящий режим валидатор не может создать новый экземпляр com.rakuten.gep.itemwrapper.external.entities.validator.NumberOfObjectsValidater, потому что он не имеет стандартный конструктор по умолчанию.

Вы должны быть в состоянии воспроизвести проблему можно, выполнив следующий код:

public static void test() throws InstantiationException, IllegalAccessException { 
    try { 
     com.rakuten.gep.itemwrapper.external.entities.validator.NumberOfObjectsValidater.class.newInstance(); 
    } 
    catch (InstantiationException e) { 
     throw e; 
    }  
    catch (IllegalAccessException e) { 
     throw e; 
    } 
    catch (RuntimeException e) { 
     throw e; 
    } 
} 

Решение будет добавить общественный модификатор конструктору NumberOfObjectsValidater
