Пожалуйста, смотрите ОБНОВЛЕНИЕ после журнала ошибок
У меня есть такой код в весеннем приложении:
@Query("SELECT e.status FROM EquipmentContract e")
List<String> getTerminationDates();
и это работает. Но если я изменю запрос, добавлю поле datetime type
@Query("SELECT e.status, e.terminated_date FROM EquipmentContract e")
это не так, выставляя мне журнал ошибок вроде этого:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'securityConfiguration' defined in file [C:\Users\sergei.klevtsov\Documents\Projects\Work\ntt-inventory\target\classes\com\acn\inventory\config\SecurityConfiguration.class]: Unsatisfied dependency expressed through constructor parameter 5; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.zalando.problem.spring.web.advice.security.SecurityProblemSupport': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'handlerExceptionResolver' defined in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerExceptionResolver]: Factory method 'handlerExceptionResolver' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mvcConversionService' defined in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.format.support.FormattingConversionService]: Factory method 'mvcConversionService' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'equipmentContractRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract java.util.List com.acn.inventory.repository.EquipmentContractRepository.getTerminationDates()!
должна ли в запросе использоваться дополнительная конструкция для обработки datatime или ...?
После некоторых изменений ошибка во время компиляции исчезла, но теперь после загрузки REST-источника она говорит:
{
"type" : "http://www.jhipster.tech/problem/problem-with-message",
"title" : "Internal Server Error",
"status" : 500,
"detail" : "Could not write JSON: java.sql.Timestamp cannot be cast to [Ljava.lang.Object;; nested exception is com.fasterxml.jackson.databind.JsonMappingException: java.sql.Timestamp cannot be cast to [Ljava.lang.Object; (through reference chain: java.util.ArrayList[0])",
"path" : "/api/equipment-contracts/terminations/dates",
"message" : "error.http.500"
}
мне кажется, что решение близко (?)
