從Rest控制器調用Java Spring中的特定查詢

Question

我正在嘗試通過其字段customerId過濾名為Measure的表。 這是該路徑的控制器開始處的樣子：

    @RequestMapping(method = GET, path = "/nodes/{id}/ports/{portid}/measures")
@ResponseBody
public ResponseEntity<?> getPortMeasures(@PathVariable long id, @PathVariable long portid,
                                         @RequestParam Optional<Long> from,
                                         @RequestParam Optional<String> order,
                                         @RequestParam Optional<String> countername,
                                         @RequestParam Optional<Long> to) {

其次是調用查詢底層的方法

if (order.isPresent() && order.get().equals("asc")) {
            return ResponseRestBuilder.createSuccessResponse(
                    measureRepository.
                            searchAsc
                                    (networkElementList.get(0).ip, portList.get(0).rack, portList.get(0).frame, portList.get(0).slot,
                                            portList.get(0).portSerial, countername.get(), from.orElse(0L), to.orElse(99999999999999999L)));
        }
        else{
            return ResponseRestBuilder.createSuccessResponse(
                    measureRepository.
                            searchDesc
                                    (networkElementList.get(0).ip, portList.get(0).rack, portList.get(0).frame, portList.get(0).slot,
                                            portList.get(0).portSerial, countername.get(), from.orElse(0L), to.orElse(99999999999999999L)));
        }

這是查詢的樣子：

    @Query("SELECT mes FROM Measure mes WHERE " +
        "mes.nodeIp = (:nodeIp) AND " +
        "mes.rack = (:rack) AND " +
        "mes.frame = (:frame) AND " +
        "mes.slot = (:slot) AND " +
        "mes.portSerial = (:portSerial) AND " +
        "lower(mes.counterName) LIKE concat('%', lower(:countername), '%')  AND"+
        "mes.timestamp > (:timestamp1) AND " +
        "mes.timestamp < (:timestamp2) "+
        "ORDER BY mes.timestamp DESC")


List<Measure> searchDesc(@Param("nodeIp") String nodeIp, @Param("rack") String rack, @Param("frame") String frame,
                            @Param("slot") String slot, @Param("portSerial") String portSerial, @Param("countername") String countername,
                         @Param("timestamp1") Long timestamp1, @Param("timestamp2") Long timestamp2);



@Query("SELECT mes FROM Measure mes WHERE " +
        "mes.nodeIp = :nodeIp AND " +
        "mes.rack = :rack AND " +
        "mes.frame = :frame AND " +
        "mes.slot = :slot AND " +
        "mes.portSerial = :portSerial AND " +
        "lower(mes.counterName) LIKE concat('%', lower(:countername), '%') AND " +
        "mes.timestamp > :timestamp1 AND " +
        "mes.timestamp < :timestamp2 "+
        "ORDER BY mes.timestamp ASC")


List<Measure> searchAsc(@Param("nodeIp") String nodeIp, @Param("rack") String rack, @Param("frame") String frame,
                         @Param("slot") String slot, @Param("portSerial") String portSerial, @Param("countername") String countername,
                         @Param("timestamp1") Long timestamp1, @Param("timestamp2") Long timestamp2);

它不會過濾任何內容，因為控制器會回復0行。 我100％確信有實際的行，因為我已經檢查了其他的休息電話。 我究竟做錯了什么？

Answer 1

問題很可能與timestamp字段有關，從代碼中似乎您傳遞了很長時間，但實際上它正在等待timestamp文字，jpa中的timestamp文字格式為{ts '2009-11-05 12-45-52.325'} ...只是檢查一下，嘗試從查詢中刪除時間戳，然后再次放入並手動提供文字...如果{ts '2009-11-05 12-45-52.325'} ，則需要找到一種方法來解析傳遞的long到相應的文字

問題在於字段portList.get（0）.rack為“ null”。 顯然，這使整個查詢無法正常工作。
