JPA错误：无法将状态字段路径“***”解析为有效类型

这里的状态是从一个枚举中获取的，我有一个用于此的转换器类。但在运行时，它给出了以下异常，即在转换器类com.orsbv.hcs.model.ScheduleStatus$TypeConverter上调用convertToDatabaseColumn时，值为1.e

关于这个问题的任何帮助都将非常有用。请寻求专家的关注

这是错误日志：

After running the following query method....   


@Query(value = "select s.owner, " +
            "count(case when s.status = 3 then 1 else null end) as agreed," +
            "count(case when s.status = 2 then 1 else null end) as rejected," +
            "count(case when s.status = 1 then 1 else null end) as pending " +
            "from Schedule s where (s.owner = ?1) " +
            "group by s.owner")

你也应该这样做

更改s.status=3这应该是枚举 示例s.status=status.ACTIVE

或

更改s.Status应为整数=3

示例：s.status.id=3

通过使用完全限定的包名，可以解决此问题

ReportQuery(referenceClass=Schedule jpql="select s.owner, count(case when s.status = 1 then 1 else null end) as agreed,count(case when s.status = 2 then 1 else null end) as rejected,count(case when s.status = 3 then 1 else null end) as pending from Schedule s where (s.owner = ?1) group by s.owner")

你的问题是？标题和问题内容之间的关系在哪里？什么操作触发了异常？你是怎么解决的？问题中没有QueryDSL，所以标题fixed@JensSchauder请现在看一看。希望您现在就可以得到它。请添加您的转换器类和枚举。@Queryvalue=select s.owner，+countcase当s.status=com.orsbv.hcs.model.ScheduleStatus.AGREED时，则1否则按约定结束null，+countcase当s.status=com.orsbv.hcs.model.ScheduleStatus.REJECTED时，则1 else null结束为REJECTED，+countcase当s.status=com.orsbv.hcs.model.ScheduleStatus.PENDING时，则1 else null结束为来自计划s的PENDING+，其中s.owner=？1+由s.owner分组。通过使用完全限定的包名，解决了此问题。

@Query(value = "select s.owner, " + "count(case when s.status = com.orsbv.hcs.model.schedule.ScheduleStatus.AGREED then 1 else null end) as agreed," + "count(case when s.status = com.orsbv.hcs.model.schedule.ScheduleStatus.REJECTED then 1 else null end) as rejected," + "count(case when s.status = com.orsbv.hcs.model.schedule.ScheduleStatus.PENDING then 1 else null end) as pending " + "from Schedule s where (s.owner = ?1) " + "group by s.owner")
