Question

我有三个名为 SLSNotification，SLSWorkflow和Importer 的表这些表不是任何关系......我想得到三个表来进行jasper报告..所以我为它创建一个原生查询..它在MySQL上工作正常......但是当我将它添加到SLSWorkflowRepository只检索工作流类时..我想从这个存储库中获取其他类...我认为它只检索因为我这样写这个

  @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（）找到其他类吗？

如果我错了，请给出一些另一种方式...

如何连接三张桌子......请帮帮我一个人......

Answer 1

您只获得SLSIWorkflow，因为您只在WorkflowServices的以下代码中返回该实体。

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

如果您返回Object，则会将表格slsnotification，sls_wrkflw，importers中的所有字段设为Object[]。

另外，使用普通JOIN，默认情况下会产生INNER JOIN。如果一个联合表不满足ON条件，则不会返回任何内容。如果您使用LEFT JOIN以便返回null，那就太好了。
