How to query LocalDateTime with LocalDate?


I've got a class which contains an atttribute of java.time.LocalDateTime type.

public class MyClass{
    // ...
    private LocalDateTime fecha;
    // ...
}

I'm using Spring Data repositories. What I want to accomplish is to query entities according to a date:

@Service
public interface IRepository extends CrudRepository<MyClass, UUID> {
    // ...
    public void deleteByFecha(LocalDate fecha);
    // ...
}

But this does not work, as an exception is thrown:

org.springframework.dao.InvalidDataAccessApiUsageException: Parameter value [2016-10-05] did not match expected type [java.time.LocalDateTime (n/a)];

So the question is how can I query MyClass in database by fecha but with a LocalDate?

EDIT Just in case somebody faces the same issue, I've come up with one solution: modify the Repository's method so that it looks as follows:

import org.springframework.transaction.annotation.Transactional;
import org.springframework.data.jpa.repository.Modifying;
import org.springframework.data.jpa.repository.Query;
// ...

@Service
public interface IRepository extends CrudRepository<MyClass, UUID> {

    @Transactional
    @Modifying
    @Query("DELETE FROM MyClass mtc WHERE YEAR(mtc.fecha)=?1 AND MONTH(mtc.fecha)=?2 AND DAY(mtc.fecha)=?3")
    public void deleteByFecha(Integer year, Integer month, Integer day);

}

Solution

  • Try this (not tested):

    public interface IRepository extends CrudRepository<MyClass, UUID> {
        // ...
        default void delByFecha(LocalDate fecha) {
    
            deleteByFechaBetween(fecha.atStartOfDay(), fecha.plusDays(1).atStartOfDay());
    
        }
    
        void deleteByFechaBetween(LocalDateTime from, LocalDateTime to);
        // ...
    }
