Java套接字，设置连接超时等超时，但在获取inputStream时仍然卡住

Here's my code

这是我的代码

Socket s = new Socket();
s.setSoTimeout(5000);
s.connect(url, 5000);
InputStreamReader inputStreamReader = new InputStreamReader(s.getInputStream());
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String line;
while ((line = bufferedReader.readLine()) != null){
    System.out.println(line);
}
Socket s = new Socket
