我有三个表，分别称为SLSNotification、SLSWorkflow 和 Importer这些表没有任何关系...我想为 jasper 报告获取三个表..所以我为它创建了一个本机查询..它在 MySQL 上运行良好...但是当我将它添加到 SLSWorkflowRepository 时，只检索工作流类。我也想从这个存储库中获取其他类……我认为它检索只是因为我这样写

  @Query(value = "select * from slsnotification a join sls_wrkflw b on a.snumber = b.snumber join importers c on c.importer_vat_number =  a.importervat where a.importervat = :importerVatNumber and a.snumber = :snumber", nativeQuery = true)
    Object getForPrint(@Param("snumber") Long snumber,@Param("importerVatNumber") String importerVatNumber);

我可以为SLSIWorkflow getForPrint()方法获取其他类...

如果我错了，请给一些其他方式...

这是我的模型

如何连接三个表...请帮助我的人...

您只得到一个SLSIWorkflow，因为您仅在以下代码中返回该实体WorkflowServices。

public SLSIWorkflow getApplicationForPrint(Long SNumber, String importerVatNumber) {
    return workflowRepository.getForPrint(SNumber, importerVatNumber);
}

如果您返回 an Object，它将具有表中的所有字段slsnotification, sls_wrkflw,importers作为Object[].

加上使用 PlainJOIN它将导致INNER JOIN默认情况下。如果一个连接表不满足ON条件，这将不会返回任何内容。如果您使用LEFT JOIN这样会返回空值，这是很好的。
