在Java Spring框架中使用LocalDateTime，对于MongoDb集合仍然给出Date,parse()错误

Question

我想根据 MongoDB 集合“processing-status”上的“listing status”和“createdOn”日期生成一个列表报告。 “listingStatus”字段属于嵌套集合。

ListingService方法如下：-

@Override
public List<ProcessingStatus> getProcessingStatusByListingStatusAndDate(String listingStatus,LocalDateTime startDate, LocalDateTime endDate) {

    Query query = new Query();

    logger.info("UTC Start Date: " + startDate);
    logger.info("UTC End Date: " + endDate);
    
    query.addCriteria(Criteria.where("bookscape.listingStatus").is(listingStatus));
    query.addCriteria(Criteria.where("createdOn").gte(startDate).lte(endDate));
    
    logger.info("Generated Query: " + query);
    logger.info("Generated Query through Serialization: " + SerializationUtils.serializeToJsonSafely(query));
    
    List<ProcessingStatus> ps = mongoTemplate.find(query, ProcessingStatus.class);
    logger.info("Query result size " + ps);
    return mongoTemplate.find(query, ProcessingStatus.class);

}

---

控制器”将使用以下方法调用服务方法：-

@GetMapping("/filter")public ResponseEntity<?> getProcessingStatusByNestedListingStatusAndDate(
        @RequestParam String listingStatus,
        @RequestParam @DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME) LocalDateTime  startDate,
        @RequestParam @DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME) LocalDateTime  endDate) {

    logger.info("Method Parameters ");
    logger.info("Listing Status: " + listingStatus);
    logger.info("Start Date: " + startDate);
    logger.info("End Date: " + endDate);
    
    // Call the service method with the listing status and date range
    List<ProcessingStatus> results =  
             listingReport.getProcessingStatusByListingStatusAndDate("Success", startDate, endDate);
    
    // Output the results
    System.out.println("Results: " + results.size());
    
    if (results.isEmpty()) {
        return ResponseEntity.status(HttpStatus.NOT_FOUND)
                     .body(Collections.singletonMap("message", "No records 
                            found matching the filter criteria."));
    } else {
        // Generate CSV report
        byte[] reportBytes = generateCsvReport(results);
    
        // Set headers for the CSV file download
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);
        headers.setContentDispositionFormData("filename", 
                                            "processing_statuses_report.csv");
    
        return new ResponseEntity<>(reportBytes, headers, HttpStatus.OK);
    }
}

private byte[] generateCsvReport(List<ProcessingStatus> processingStatuses) {

    StringBuilder csvBuilder = new StringBuilder();
    csvBuilder.append("Batch ID, ISBN, Listing Status, Created Date\n");
    for (ProcessingStatus status : processingStatuses) {
        String listingStatus = getStatusListing(status);
        csvBuilder.append(status.getBatchId()).append(",")
                .append(status.getIsbn()).append(",")
                .append(listingStatus).append(",")
                .append(status.getCreatedOn() != null ? 
          status.getCreatedOn().toString() : "").append("\n");
    }
    return csvBuilder.toString().getBytes(StandardCharsets.UTF_8);

}

private String getStatusListing(ProcessingStatus status) {
    if (status.getAmazonEasyShip().getAmazonEasyShipDel().getListingStatus() != null)
        return status.getAmazonEasyShip().getAmazonEasyShipDel().getListingStatus();
    else if (status.getAmazonEasyShip().getAmazonEasyShipMum().getListingStatus() != null)
        return status.getAmazonEasyShip().getAmazonEasyShipMum().getListingStatus();
    else if (status.getAmazonFlex().getAmazonFlex().getListingStatus() != null)
        return status.getAmazonFlex().getAmazonFlex().getListingStatus();
    else if (status.getFlipkartHSP().getFlipkartHSP().getListingStatus() != null)
        return status.getFlipkartHSP().getFlipkartHSP().getListingStatus();
    else if (status.getFlipkartLSP().getFlipkartLSP().getListingStatus() != null)
        return status.getFlipkartLSP().getFlipkartLSP().getListingStatus();
    else if (status.getBookscape().getBookscape().getListingStatus() != null)
        return status.getBookscape().getBookscape().getListingStatus();
    else
        return "";
}

输出（第一行因太长而断）：-

我尝试在“ProcessingStatus”以及使用“createdOn”的任何地方使用“LocalDateTime”而不是“Date”字段。

---

我还尝试按如下方式进行UTC转换：-

// Convert the dates to UTC
ZoneId istZone = ZoneId.of("Asia/Kolkata");
ZoneId utcZone = ZoneId.of("UTC");
ZonedDateTime istStartDateTime
        = ZonedDateTime.ofInstant(startDate.toInstant(), istZone);
ZonedDateTime istEndDateTime =
        ZonedDateTime.ofInstant(endDate.toInstant(), istZone);
Date utcStartDate =
        Date.from(istStartDateTime.withZoneSameInstant(utcZone).toInstant());
Date utcEndDate =
        Date.from(istEndDateTime.withZoneSameInstant(utcZone).toInstant());

List<ProcessingStatus> processingStatuses =
        listingReport.getProcessingStatusByListingStatusAndDate(
               listingStatus, utcStartDate, utcEndDate);

logger.info("Listing Status: " + listingStatus);
logger.info("UTC Start Date: " + utcStartDate);
logger.info("UTC End Date: " + utcEndDate);

请建议如何解决此问题。

Answer 1

类型错误

在 Spring 中，常量

DateTimeFormat.ISO.DATE_TIME

表示时刻，是在特定的 UTC 偏移量中看到的日期（或者可能是时区，我不确定，因为我不使用 Spring ).

您选择使用

java.time.LocalDateTime

对象。该课程“不”代表一个时刻。该类仅表示具有当天时间的日期，但缺少与 UTC 或时区的偏移量的上下文。 代表一个时刻

如果您的软件试图表示某个时刻、时间线上的特定点，请勿使用

LocalDateTime

。使用

Instant

、

OffsetDateTime

或

ZonedDateTime

。
