xfire webservice怎么判断能不能连上一个接口

Question

xfire webservice怎么判断能不能连上一个接口，如果不能连在几秒内断开，不然他一直连，然后报：caught when processing request: Connection timed out: connect错误，这个过程要很长时间。

Answer 1

URL _url = new URL(url);
HttpURLConnection httpConnection = (HttpURLConnection)_url.openConnection();
httpConnection.setReadTimeout(20000);//设置http连接的读超时,单位是毫秒

    httpConnection.connect();
    Client _client = new Client(httpConnection.getInputStream(), null);
    _client.setProperty(CommonsHttpMessageSender.HTTP_TIMEOUT, String.valueOf( 20000 ));//设置发送的超时限制,单位是毫秒;
    _client.setProperty(CommonsHttpMessageSender.DISABLE_KEEP_ALIVE, "true");
    _client.setProperty(CommonsHttpMessageSender.DISABLE_EXPECT_CONTINUE, "true");
