获取一个302地址跳转后的地址

获取一个302地址跳转后的地址
这是源代码,但是不好使,有人帮我看看吗

public static void main(String[] args) throws IOException {

        String link = "https://developer.lanzoug.com/file/?VDJVa15vDz4FDFNrADVRPQY5DzdV7wutUf9WuVe1UspUsQXXD/lU6VSBUK5WLAFhAykDbVcuVzMFa1I4AThRD1Q9VWZePg9jBWZTMQBmUWEGZQ8zVTsLL1EwViNXNlJiVGAFaw9rVDlUMFA/VjcBJgMpA3ZXNVdnBTJSZgFvUX9UZVUyXiwPagVnUyoAMlFnBmwPPVUyC21RblZiV21SY1RmBTMPYVQ1VDVQMlY6ATgDbQMwVzhXZwUzUjIBblEzVDJVY15lD2wFYlM8AHpRMQYsD2FVLAt8USVWNVd5UjpUMAVvD2NUNlQ0UDVWOgE3A28DIFd8VzwFb1IxATtRbVRlVTReNQ9tBWRTMwBmUWUGZA87VSQLJ1FwVjZXZ1IkVGkFYw9kVDZUNFAxVjQBMQNpAzNXMVdzBXdSJAEqUW1UZVU0XjUPbgVkUzUAbVFgBm0POlUsC3xRP1YgVzZSYlRlBWcPfFQxVDdQP1YsATYDbgMoVzlXYQUx";
        //设置不允许重定向
        RequestConfig config = RequestConfig.custom().setRedirectsEnabled(false).build();

      //使用 CloseableHttpClient 而非 HttpClient
        CloseableHttpClient httpClient = HttpClients.custom().setDefaultRequestConfig(config).build();
        HttpResponse response = null;
        InputStream is = null;
        String body = null;
        StringBuilder res = new StringBuilder();
        try {
            response = httpClient.execute(new HttpGet(link));
            HttpEntity entity = response.getEntity();
            // 读取响应内容
            if (entity != null) {
                is = entity.getContent();
                BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"));
                while ((body = br.readLine()) != null) {
                    res.append(body);
                }
            }

        } catch (IOException e) {
            throw new RuntimeException(e);
        }
        System.out.println(res);
        int code = response.getStatusLine().getStatusCode();
        System.out.println(code);
        String newuri="";
        if (code == 302) {
            Header header = response.getFirstHeader("location"); // 跳转的目标地址是在response的 HTTP-HEAD 中的，location的值
            newuri = header.getValue(); // 这就是跳转后的地址，再向这个地址发出新申请，以便得到跳转后的信息是啥。
            System.out.println(newuri);
        }
    }
