java - Spring - 两种不同的 POST 方法，具有相同的 URL，但生成的内容类型不同

Question

我有以下 Controller :

@RequiredArgsConstructor
@RestController
public class OwnerViewController implements ApiOwnerViewController {

    private static final String TEXT_CSV = "text/csv";

    private final PrivateOwnerFacade privateOwnerFacade;

    @PostMapping("/boat/v1/private-owners/search")
    public OwnerViewResponse searchOwners(@Valid @RequestBody SearchOwnersRequest request,
                                          Pageable pageable) {
        return privateOwnerFacade.findOwners(request, pageable);
    }

    @PostMapping(value = "/boat/v1/private-owners/search", produces = TEXT_CSV)
    public ResponseEntity<Resource> exportToCsv(@Valid @RequestBody SearchOwnersRequest request, Pageable pageable)
            throws IOException {

因此，我有两个方法映射到同一网址，并且都接受 POST 请求，但生成不同的内容类型 - 第一个生成 application/json，而第二个生成 text/csv.

然后，当我尝试发出请求并设置 header 时 接受:text/csv 我从服务器收到 406。

我想知道用spring真的可以做这样的事情吗？或者是更改第二个方法以使其接受 GET 请求的唯一方法？

谢谢

@RequiredArgsConstructor
@RestController
public class SearchController {

    @PostMapping(value = "/search", produces = {APPLICATION_JSON})
    public SearchResponse search(@Valid @RequestBody SearchRequest request,
                                          Pageable pageable) {
    }

    @PostMapping(value = "/search", produces = {TEXT_CSV})
    public ResponseEntity<Resource> export(@Valid @RequestBody SearchRequest request, Pageable pageable) throws IOException {

    }
