Question

在我的Web应用程序中，我有一个全局静态HttpClient，它在应用程序的许多部分中使用。它是这样创建的：

MultiThreadedHttpConnectionManager connectionManager = new MultiThreadedHttpConnectionManager();
HttpConnectionManagerParams params = new HttpConnectionManagerParams();
params.setConnectionTimeout( 15000 );
params.setSoTimeout( 15000 );
connectionManager.setParams(params);
httpclient = new HttpClient(connectionManager);
HttpClientParams clientParams = new HttpClientParams();
clientParams.setParameter("http.protocol.allow-circular-redirects", true);
clientParams.setParameter("http.protocol.max-redirects", 4);
httpclient.setParams(clientParams);

对于大多数使用来说，超时很好，但在特定的通话中，我希望更短的超时。所以我有：

GetMethod get = new GetMethod(finalUrl);

get.getParams().setParameter("http.socket.timeout", new Integer(1000));
get.getParams().setParameter("http.connection.timeout", new Integer(1000));
HttpClientUtil.getShortTimeoutInstance().executeMethod(get);

它不起作用。连接超时仍为15000.我可以在GetMethod中设置特定的连接超时而无需创建新的HttpClient实例（这是因为我相信创建一个新的HttpClient实例不是一个好主意。）

你可能想看看

./ IMPL /康恩/ tsccm / ThreadSafeClientConnManager.java

方法

ClientConnectionRequest requestConnection(final HttpRoute route, 
                                          final Object state)

为路由初始化连接池后，将继续使用套接字timeOut的原始配置值，除非您扩展/覆盖它。

public ClientConnectionRequest requestConnection(
        final HttpRoute route,
        final Object state) {

    final PoolEntryRequest poolRequest = pool.requestPoolEntry(
            route, state);

    return new ClientConnectionRequest() {

        public void abortRequest() {
            poolRequest.abortRequest();
        }

        public ManagedClientConnection getConnection(
                long timeout, TimeUnit tunit) throws InterruptedException,
                ConnectionPoolTimeoutException {
            if (route == null) {
                throw new IllegalArgumentException("Route may not be null.");
            }

            if (log.isDebugEnabled()) {
                log.debug("Get connection: " + route + ", timeout = " + timeout);
            }

            BasicPoolEntry entry = poolRequest.getPoolEntry(timeout, tunit);
            return new BasicPooledConnAdapter(ThreadSafeClientConnManager.this, entry);
        }

    };

}
