如果在 Spring Data JPA 中为 null 或为空，如何在 @Query 中跳过 @Param [英] How to skip @Param in @Query if is null or empty in Spring Data JPA

问题描述

@Query(value = "Select f from Documents f " +
        "RIGHT JOIN f.documentStatus ds " +
        "where f.billingAccount.accountId  in :billingAccountIdList " +
        " and ds.statusCode in :paymentStatuses" +
        " and f.paymentDate < :paymentDate")
List<FinancialDocumentEntity> getFinancialDocumentsOverdue(@Param("billingAccountIdList")List<String> billingAccountIdList,
                                                           @Param("paymentStatuses") List<String> paymentStatuses,
                                                           @Param("paymentDate") Date paymentDate);

我有上面的查询.如果为 null 或为空，可以跳过查询方法中的搜索参数，例如 @Param("paymentStatuses") ?

I have query like above. It is possible to skip searching param for example @Param("paymentStatuses") in query method if is null or is empty ?

推荐答案

尝试改变

" and ds.statusCode in :paymentStatuses"

进入

" and (:paymentStatuses is null or ds.statusCode in :paymentStatuses)"
