Jpa返回对象必须是与Entity类么？

Question

  @Query(value = "SELECT id as topicId,content FROM bbs_topic WHERE create_time BETWEEN ?1 AND ?2",nativeQuery = true)
    List<IndexObject> getBbsTopicListByDate(Date fileupdateDate, Date topiclastupdate);

其中IndexObject 是显示层vo。
然后报错

org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.Object[]] to type [com.wayne.common.lucene.entity.IndexObject] for value '{59, 再发表一次看看那}'; nested exception is org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.Integer] to type [com.wayne.common.lucene.entity.IndexObject]

度娘了一下
怀疑 jpa返回对象必须是与Entity类相关（Entity就是配置了Java类与数据库映射的Java类）
有大神知道对么？
