Question

我正在开发一个Spring项目。

我现在正在这样做。

public ResponseEntity<?> create(@RequestBody final Some entity) {
    // persist the entity here
    final URI location = uriComponentsBuilder.path("{id}").buildAndExpand(entity.getId()).toUri();
    return ResponseEntity.created(location).build();
}

我找到了@ResponseStatus。

@ResponseStatus(HttpStatus.CREATED)
public void create(@RequestBody @NotNull final BaseType entity) {
    // persist the entity here
    // Location header to where?
}

有没有办法以这种方式发送Location标题？

Answer 1

您可以返回如下所示的响应实体：

 return new ResponseEntity<>(location, HttpStatus.CREATED);

或

HttpHeaders headers = new HttpHeaders();
headers.add(location);
return new ResponseEntity<>(headers, HttpStatus.CREATED);

Answer 2

试试这个。它返回您首选的标题和状态，没有正文。

@ResponseStatus(HttpStatus.I_AM_A_TEAPOT)
@RequestMapping("/teapot")
public HttpHeaders dummyMethod() {
    HttpHeaders h = new HttpHeaders();
    h.add("MyHeader", "MyValue");
    return h;
}

如何发送带有无效响应的标头？
