spring boot错误处理代码404空白页

Question

我的第二个问题是关于内部服务器错误500。我如何实现它，如何测试它？

@CrossOrigin
@RequestMapping(value = "/blaa/{startDate}/{endDate}", method = RequestMethod.GET)
public ResponseEntity<List<Nodes>> listsOfbla(@PathVariable Long startDate,
        @PathVariable Long endDate) {

    startEndDateRequestTotal.inc();

    List<Nodes> listOfbla= NodesService.getFromToData(startDate, endDate);

    LOG.info("GET Request was made with two paramaters ", startDate, endDate);
    for (int i = 0; i < listOfbla (); i++) {
        if (listOfbla(i).getStampm().equals(startDate)) {
            for (int j = 0; j < listOfbla (); j++) {
                if (listOfbla(j).getStampm().equals(endDate)) {
                    return new ResponseEntity<List<Nodes>>listOfbla HttpStatus.OK);
                }
            }
        } else {
            return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
        }
    }

    if (listOfbla.isEmpty()) {
        return new ResponseEntity<>(HttpStatus.NOT_FOUND);
    }
    LOG.info("Retruning Nodes objects from specified date");
    return new ResponseEntity<List<Nodes>>(listOfbla, HttpStatus.OK);
}

对于您的第一个问题：这就足够了，您收到状态代码，您可以制作，例如。如果状态码=404，给我发这个消息。
