JpaRepository Không được hỗ trợ cho hoạt động DML [xóa truy vấn]

Question

Tôi đã viết một truy vấn, để xóa một số đối tượng, trong giao diện mở rộng JPaRepository của tôi, nhưng khi tôi thực hiện truy vấn Nó ném một ngoại lệ! Bất cứ ai có thể giải thích nó cho tôi và cảm ơn bạn trước :)

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); 

} 

tôi đã nhận lỗi này, có thể anyne Xin vui lòng, giải thích này đối với tôi, và cảm ơn tất cả các bạn :)

Answer 1

Hãy thử điều này:

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); 

} 

Bất cứ khi nào bạn đang cố gắng sửa đổi một kỷ lục trong db, bạn phải đánh dấu nó @Transactional cũng như @Modifying, mà hướng dẫn xuân mà nó có thể sửa đổi bản ghi hiện có

Answer 2

tôi đã cùng một vấn đề và tôi đã cố gắng @ của Afridi câu trả lời mà làm việc tốt nhưng thực hành xấu, theo như tôi hiểu. bạn không nên sử dụng chú thích @Transactional trong lớp kho lưu trữ nhưng các lớp dịch vụ (và triển khai). xin vui lòng tìm câu trả lời dưới đây.

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); 

} 

hãy chắc chắn để sử dụng hàng nhập khẩu đúng.
