我正在使用jpa连接到mysql。当我使用的查询表数据库如下：错误查询jpa弹簧启动
public interface CommentRepository extends JpaRepository<Comment1, Integer>{
\t @Query(value = "SELECT * FROM comment1 WHERE contribution_id=:contributionId",nativeQuery = true)
\t List<Comment1> findByContributionId(@Param("contributionId") String contributionId);
