用 jpql 过滤 redis 数据不起作用

Question

Is it possible to create a JPQL filter with redis?

if I try this:

List<ContingencyDTO> findAll();

works:

but if i try with jpql no.

@Repository
public interface ContingencyRepository extends 
CrudRepository<ContingencyDTO,Integer>, QueryByExampleExecutor<ContingencyDTO>  
{

List<ContingencyDTO> findByInitialZipCodeLessThanEqual(Long initialZipCode);

}

return this message error: Erro:: handleAPIException:: Exception

org.springframework.dao.InvalidDataAccessApiUsageException: LESS_THAN_EQUAL (1): [IsLessThanEqual, LessThanEqual] is not supported for Redis query derivation;. nested exception is java.lang:IllegalArgumentException: LESS_THAN_EQUAL (1), [IsLessThanEqual, LessThanEqual] is not supported for Redis query derivation!

private @Indexed Long initialZipCode;

Please check the attribute name in Entity ContingencyDTO . If the attribute name is zipcode , then above method should have worked. If the attribute name is zipCode then the method name should be findByZipCode .

If you want to retrieve all ContingencyDTO entities for a given zipCode then List<ContingencyDTO> findByZipCode(String zipCode); should work. @Query annotation isn't required in this case and in above case too, if the issue is solved as per this explanation.
