如何在@RestController中使用Pageable？

Question

我知道这Pageable来自spring-data-域名.

有没有直接使用任何优雅的方式org.springframework.data.domain.Pageable在@RestController？

我试过跟随.

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

结果不是我的预期.

...: ~ $ 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
}

Answer 1

它应该返回不是Pageable而是Page.

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

Pageable是请求方,包含您需要的内容.但Page包含结果.
