Question

我有以下控制器：

@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，我有两个映射到相同url的方法，它们都接受POST请求，但生成的内容类型不同-第一个生成application/json，第二个生成text/csv。

然后，当我尝试发出请求并设置标头时 Accept: text/csv我从服务器收到406。

我想知道春天真的有可能做这种事情吗？还是更改第二种方法以使其接受GET请求的唯一方法？

谢谢

只需将一个方法与@PostMapping一起使用，返回一个响应实体并动态设置Content-Type-Response-Header。

@RestController
public class TestController {

    @GetMapping("/api-endpoint")
    public ResponseEntity<String> method(@RequestParam("produces") String produces) {

        HttpHeaders responseHeaders = new HttpHeaders();

        if (produces.equals("text/csv")) {
            responseHeaders.setContentType(new MediaType("text", "csv"));
            return new ResponseEntity<String>("foo;bar", responseHeaders, HttpStatus.OK);
        } else {
            responseHeaders.setContentType(new MediaType("application", "json"));
            return new ResponseEntity<String>("{\"foo\": \"bar\"}", responseHeaders, HttpStatus.OK);
        }
    }
}

问题是text / csv的请求与两个端点都匹配。
您可以在注释上使用负值，因此第一个将仅匹配非文本/ csv请求：

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

Answer 3

@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 {

    }


}

Spring-具有相同URL但产生的内容类型不同的两种不同的POST方法
