将 Spring 应用程序从 Hibernate 4.3.1.Final 迁移到 5.4.27.Final

如何解决将 Spring 应用程序从 Hibernate 4.3.1.Final 迁移到 5.4.27.Final

我正在尝试在旧的 Spring 应用程序中从 hibernate 4.3.1.Final 迁移到 5.4.27.Final（大多数 Spring 组件都在 4.3.13.Final 版本上）。更新版本修复几个小问题（类导入）并使用 maven 构建应用程序后，我在尝试在 Tomcat 7.0.107 上部署此 Web 应用程序时出现以下错误（堆栈跟踪的一部分指向根异常）：>

此 JPQL 在之前的版本中运行和部署良好。

上述实体的相关部分如下：

  private Date             ackDate;

  @Column(name = "message",length = MESSAGE_MAX_LENGTH,nullable = true)
  private String           message;

报警日志存储库：

  @Transactional(readOnly = true)
  public interface AlarmlogRepository extends JpaRepository<Alarmlog,Long>,JpaSpecificationExecutor<Alarmlog> {

    @Query("FROM Alarmlog " + //
        "WHERE zipato=:zipato " + //
        "  AND alarmId=:alarmId " + //
        "  AND subtype='ZONE' " + //
        "  AND subtypeUuid=:zone " + //
        "  AND timestamp BETWEEN :start AND :end" + //
        "  AND needAck=true " + //
        "  AND size(Alarmlog.acks)=0")
    List<Alarmlog> findAlarmlogsByZoneAndDatesAndNeedsAck(@Param("zipato") Zipato p_zipato,@Param("alarmId") Integer p_alarmId,@Param("zone") String p_zone,@Param("start") Date p_start,@Param("end") Date p_end);

我尝试在谷歌上搜索此错误，但找不到无法识别的 plural-attribute 的确切组合。我还尝试调试到一定程度，发现此 Set 未被识别为集合类型，或者更准确地说 acks Set 不在列表中，因此无法识别为plural-attribute。

我不知道如何解决这个问题...

有什么想法吗？

解决方法

对于该查询，您应该为实体 AlarmLog 设置标识符，并按以下方式在 where 条件中使用该标识符：

...
@Query("FROM AlarmLog al " +
        "WHERE zipato=:zipato " +
        "  AND alarmId=:alarmId " +
        "  AND subtype='ZONE' " +
        "  AND subtypeUuid=:zone " + 
        "  AND timestamp BETWEEN :start AND :end" +
        "  AND needAck=true " + 
        "  AND size(al.acks)=0")
...
