xfire webservice怎么判断能不能连上一个接口

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。

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");

应该可以设置一个超时时间的

设置连接超时时间限制啊
比如1分钟连不上就认为超时 这个自己设置

[code="java"]
//创建Service对象
TestServiceClient testClient = new TestServiceClient();

TestService testService = testClient.getTestServicePort();

//设置连接参数
HttpClientParams params = new HttpClientParams();

params.setParameter(HttpClientParams.USE_EXPECT_CONTINUE, Boolean.FALSE);

params.setParameter(HttpClientParams.CONNECTION_MANAGER_TIMEOUT, setting.getTimeout() * 1000);//单位是毫秒

Client client = Client.getInstance(testService);

client.setProperty(CommonsHttpMessageSender.HTTP_CLIENT_PARAMS, params);

XFire是基于Apache的HttpClient，所以实际上连接超时的参数是就是设置在HttpClient上的。
