Я пытаюсь написать очень простое приложение с валидатором hibernate:
мои шаги:
добавить следующую зависимость в pom.xml:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.1.1.Final</version>
</dependency>
написать код:
class Configuration {
Range(min=1,max=100)
int threadNumber;
//...
public static void main(String[] args) {
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
Validator validator = factory.getValidator();
Configuration configuration = new Configuration();
configuration.threadNumber = 12;
//...
Set<ConstraintViolation<Configuration>> constraintViolations = validator.validate(configuration);
System.out.println(constraintViolations);
}
}
И я получаю следующую команду stacktrace:
Exception in thread "main" javax.validation.ValidationException: Unable to instantiate Configuration.

Чем я ошибаюсь?
