这是代码

@Test
public void testUploadMedia() {
    FileSystemResource resource = new FileSystemResource("/Users/lanyanhua/Desktop/中文名.jpg");
    String mediaId = uploadMedia(resource);
    System.out.println("mediaId:" + mediaId);

 * 上传临时素材
 * @param resource 文件
 * @return media_id，该media_id仅三天内有效
public String uploadMedia(FileSystemResource resource) {
    String url = "https://qyapi.weixin.qq.com/cgi-bin/media/upload?access_token=ACCESS_TOKEN&type=TYPE"
            .replace("ACCESS_TOKEN", token).replace("TYPE", "image");
    RestTemplate restTemplate = new RestTemplate();
    MultiValueMap<String, Object> param = new LinkedMultiValueMap<>();
    param.add("file", resource);
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);
    HttpEntity<MultiValueMap<String, Object>> requestEntity = new HttpEntity<>(param, headers);
    ResponseEntity<JSONObject> responseEntity = restTemplate.postForEntity(url, requestEntity, JSONObject.class);
    if (responseEntity.getStatusCode() == HttpStatus.OK) {
        JSONObject body = responseEntity.getBody();
        if (body.getInteger("errcode") == 0) {
            return body.getString("media_id");
    throw new BusinessException("上传临时素材失败");
