JpaRepository不支持DML操作[刪除查詢]

我已經寫了一個查詢，刪除一些對象，在我的擴展JPaRepository的接口中，但是當我執行查詢時它會拋出一個異常！任何人都可以解釋這對我和感謝你提前:)JpaRepository不支持DML操作[刪除查詢]

查詢：

public interface LimitRepository extends JpaRepository<CLimit, Long> { 

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

}

我得到這個錯誤，可以anyne請解釋這對我來說，和謝謝大家:)

試試這個：

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); 

}

當你試圖在數據庫修改記錄，你必須標記它@Transactional以及@Modifying，其指示春天，它可以修改現有記錄

謝謝！它適用於我，並感謝您的解釋以及 – Student

只是一個簡單的觀點，該方法必須是無效的！我有這個問題，因爲在我們的項目中我們期待一個整數，所以我們也有同樣的問題，即使有註釋。我們花了一點時間才意識到，所以它可能對別人有幫助;） –

我有同樣的問題，我試圖@阿夫裏迪的據我所知，答案是正常工作，但不好的做法。您不應該在存儲庫類中使用@Transactional註釋，而應該在服務（和實現）類中使用@Transactional註釋。請找到下面的答案。

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); 

}

確保使用正確的進口。
