java - 返回 InputStream 时生成 swagger 文档

Question

我有一个将 InputStream 作为 InputStreamResource 返回的方法，当我让 swagger 生成文档时，它说返回类型是 InputStreamResource。如何更改此设置以便文档中的返回类型为 InputStream？

  @ApiOperation()
  @RequestMapping(value = "/item/{id}", produces = "application/octet-stream", method = RequestMethod.GET)
  public ResponseEntity<InputStreamResource> getStream(
          @PathVariable(value = "id") String id,
          HttpServletResponse response
  ) {
    InputStream stream = null;
    try {
      stream = getData(id);
      return ResponseEntity.ok()
              .contentType(MediaType.APPLICATION_OCTET_STREAM)
              .body(new InputStreamResource(stream));
    } catch (Exception e) {
      IOUtils.closeQuietly(stream);
      response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
      return null;
    }
  }

Answer 1

试试这个:

@ApiOperation(response = InputStream.class)

根据文档:

response : default response class from the operation
