如何在@RestController 中使用 Pageable? [英] How can I use Pageable in @RestController?

问题描述

我知道 Pageable 来自 spring-data- 域.

I know the Pageable comes from spring-data- domain.

在@RestController中是否有直接使用org.springframework.data.domain.Pageable的优雅方式?

Is there any elegant way to directly use org.springframework.data.domain.Pageable in @RestController?

我尝试跟随.

@RequestMapping(method = RequestMethod.GET,
                path = "pageable",
                produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Pageable> readPageable(@NotNull final Pageable pageable) {
    return ResponseEntity.ok(pageable);
}

结果出乎我的意料.

...: ~ $ curl -X GET --header 'Accept: application/json' 'http://localhost:8080/.../pageable?limit=1&offset=1' | python -mjson.tool
...
{
    "offset": 0,
    "pageNumber": 0,
    "pageSize": 20,
    "sort": null
}

推荐答案

返回的不是 Pageable 而是 Page.

It should return not Pageable but Page.

public Page<YourEntityHere> readPageable(@NotNull final Pageable pageable) {
    return someService.search(pageable);
}

Pageable 是请求端，其中包含您所需要的内容.但 Page 包含结果.

Pageable is request side which contains what exactly you need. But Page contains results.
