Please, see UPDATE after error log
I have such a code in the spring app:
@Query("SELECT e.status FROM EquipmentContract e")
List<String> getTerminationDates();
and it works. But if I change the query, adding the field of datetime type
@Query("SELECT e.status, e.terminated_date FROM EquipmentContract e")
it doesn't, exposing me an error log like this:
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()!
should there be some additional construction used in the query to handle datatime or...?
After some changes the error while compilation is gone, but now after loading REST source it says:
{
"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"
}
it seems to me that solution is near (?)
