Springboot存储库连续查询返回相同的结果

Question

我在存储库中遇到这个奇怪的问题，当我在同一控制器中连续执行2个数据库查询时，返回的所有结果都与第一个数据库查询相同。

示例：如果我先调用getPredictedValue（）然后再调用getCalled（），则根据这两个函数的调用顺序，第二个函数调用将获得与第一个调用相同的结果。

@Repository
public interface SomeRepository extends PagingAndSortingRepository<SomeObject, Integer> {
  @Query(nativeQuery=true, value="SELECT SUM(c.count_of_something) AS num_of_something, " +
      "TO_CHAR(c.inserted_at, 'HH24:00:00') AS hour_of_the_day " +
      "FROM some_table c " +
      "GROUP BY TO_CHAR(c.inserted_at, 'HH24:00:00') " +
      "ORDER BY TO_CHAR(c.inserted_at, 'HH24:00:00')")
  public List<SomeObject> getPredictedValue();

  @Query(nativeQuery=true, value="SELECT COUNT(c.*) AS num_of_something, " +
      "TO_CHAR(c.inserted_at, 'HH24:00:00') AS hour_of_the_day " +
      "FROM some_table c " +
      "GROUP BY TO_CHAR(c.inserted_at, 'HH24:00:00') " +
      "ORDER BY TO_CHAR(c.inserted_at, 'HH24:00:00')")
  public List<SomeObject> getCalled();
}
