java - tutorial - spring jpa repository




JpaRepository Non supportato per le operazioni DML (2)

Ho scritto una query, per cancellare alcuni oggetti, nella mia interfaccia che estende JPaRepository, ma quando esco dalla query, lancia un'eccezione! Qualcuno può spiegarlo per me e grazie in anticipo :)

Query:

public interface LimitRepository extends JpaRepository<CLimit, Long> {

  @Query("delete from CLimit l where l.trader.id =:#{#trader.id}")
  void deleteLimitsByTrader(@Param("trader") CTrader trader);

}

Ho ricevuto questo errore, qualcuno può, per favore, spiegarlo per me, e grazie a tutti :)

Eccezione:

Ho avuto lo stesso problema e ho provato la risposta di @ afridi che funziona bene, ma cattiva pratica, per quanto ho capito. non si dovrebbe usare @Transactional annotazione @Transactional nella classe repository ma le classi service (e implementation). si prega di trovare la risposta qui sotto.

LimitServiceImpl.java

import org.springframework.transaction.annotation.Transactional;
...
@Override
@Transactional
public void deleteLimitsByTrader(CTrader trader) {
// here im calling the LimitRepository interface. 
 getEntityRepository().deleteLimitsByTrader(trader);
}

LimitRepository.java

import org.springframework.data.jpa.repository.Modifying;
import org.springframework.data.jpa.repository.Query;
...
public interface LimitRepository extends JpaRepository<CLimit, Long> {

  @Modifying
  @Query("delete from CLimit l where l.trader.id =:#{#trader.id}")
  void deleteLimitsByTrader(@Param("trader") CTrader trader);

}

assicurati di utilizzare le importazioni corrette.


Prova questo:

public interface LimitRepository extends JpaRepository<CLimit, Long> {

  @Transactional
  @Modifying
  @Query("delete from CLimit l where l.trader.id =:#{#trader.id}")
  void deleteLimitsByTrader(@Param("trader") CTrader trader);

}

Ogni volta che stai cercando di modificare un record in db, devi contrassegnarlo @Transactional e @Modifying, che istruiscono Spring a modificare i record esistenti.
Il metodo di repository deve essere vuoto o l'eccezione continua a essere generata.
