最佳答案
我发现问题是不再支持 @Query 及其更改的 ?1 和 ?2 参数
** 请求存储库**
现在我的类(class)是:
package com.spring.course.repository;
import java.util.List;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;
import com.spring.course.domain.Request;
import com.spring.course.enums.RequestState;
@Repository
public interface RequestRepository extends JpaRepository<Request, Long>{
public List<Request> findAllByOwnerId(Long id);
@Query("UPDATE request SET state = :state WHERE id = :id")
public Request updateStatus(Long id, RequestState state);
}
** RequestSatageRepository**
package com.spring.course.repository;
import java.util.List;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;

import com.spring.course.enums.RequestState;
@Repository
public interface RequestSatageRepository extends JpaRepository<RequestStage, Long>{
public List<RequestStage> findAllByRequest(Long id);
@Query("UPDATE request SET state = :state WHERE id = :id")
public Request updateStatus(Long id, RequestState state);
}
