Answer 1

我发现问题是，不再更改带有更改的？1和？2参数的@Query

** RequestRepository **

现在我的课是：

this

** 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.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);

}

** UserRepository **

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.domain.RequestStage;
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);

}
