英文:
How to define direction in request with pageable parameter?
问题
我有一个查询，它以可分页的方式作为参数。我将方向定义为DESC，但这没有任何效果。这是我的请求。您能否帮助我以一种使结果以降序排序返回的方式来构建这些请求？
我已经在下面的图片中发布了我的请求。它能工作，但不能对结果进行排序。
谢谢
这是控制器代码：
@GetMapping
fun listMessages(@RequestParam conversationRef: String,
@RequestParam fromDate: Instant, @RequestParam toDate: Instant,
pageable: Pageable): PaginatedCollection<MessageVO> {
return messageService.listAll(fromDate, toDate, pageable,
conversationRef).data ?: PaginatedCollection(listOf(),
PaginationVO.build(), SortVO.build())
}
英文:
I have a query that takes pageable as a parameter. I define the direction as DESC but this takes no effect. This is my request. Could you please help me formulate the requests in a way that the results come back sorted in descending order?
I have posted my request in the picture below. It works but it does not sort the results
Thank you
This is the controller code:
@GetMapping
fun listMessages(@RequestParam conversationRef: String,
@RequestParam fromDate: Instant, @RequestParam toDate: Instant,
pageable: Pageable): PaginatedCollection<MessageVO> {
return messageService.listAll(fromDate, toDate, pageable,
conversationRef).data ?: PaginatedCollection(listOf(),
PaginationVO.build(), SortVO.build())
}

你需要发送排序字段，以便按降序进行排序。（参考链接）示例：
http://localhost:8080/people?sort=id,desc
这里的 id 是排序字段，desc 是以逗号分隔的排序方向。
因此，在 PostMan 中，您需要在 sort 参数中发送 id,desc，以按照 id 降序排序。
英文:
You need to send sort field for which you want to sort by descending.(Ref) Ex:
http://localhost:8080/people?sort=id,desc
Here id is sort field and desc is sort direction separated by a comma.
So, you need to send id,desc on sort param in PostMan for sort by id in desecending order.
