如何在客户端控制webservice调用的timeout

Answer 1

　　1,在CXF生成的stub的客户端,方式如下(CXF2.1.1):
　　SimpleServiceService srv = new SimpleServiceService();
　　SimpleService servicePort = srv.getSimpleServicePort();

　　//timeout setting
　　Client cl = ClientProxy.getClient(servicePort);

　　HTTPConduit http = (HTTPConduit) cl.getConduit();

　　HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
　　httpClientPolicy.setConnectionTimeout(10000);
　　httpClientPolicy.setReceiveTimeout(1000);
　　http.setClient(httpClientPolicy);

　　servicePort.concatenate("111", "2222");
　　其中SimpleServiceService是自动生成的stub类.

　　2,在Xfire生成的stub的客户端,方式如下(Xfire1.26):
　　SimpleServiceServiceClient serviceClient= new SimpleServiceServiceClient();
　　SimpleService servicePort = serviceClient.getSimpleServicePort();

　　HttpClientParams params = new HttpClientParams();
　　params.setParameter(HttpClientParams.USE_EXPECT_CONTINUE, Boolean.FALSE);
　　// set connection timeout
　　params.setParameter(HttpClientParams.CONNECTION_MANAGER_TIMEOUT, 2L);
　　//set response timeout
　　params.setIntParameter(HttpClientParams.SO_TIMEOUT,2);

　　Client client = Client.getInstance(servicePort);
　　client.setProperty(CommonsHttpMessageSender.HTTP_CLIENT_PARAMS, params);

　　System.out.println(servicePort.concatenate("xfire1", "xfire2"));
　　其中SimpleServiceServiceClient 是自动生成的stub类.

　　上面两种方式都是通过控制底层的http 连接来达到timeout控制,如果超时会抛出 java.net.SocketTimeoutException: Read timed out.

　　3,jax-ws的客户端:同样利用CXF的ClientProxy控制http连接:
　　URL wsdlURL = new URL("file:///D:/JAVAWorkspace/Repository/prjCXFWS/src/wsdl/prjCXFWS.wsdl");

　　QName serviceQName = new QName("test.cxfws.com/", "SimpleServiceService");

　　QName portQName = new QName("test.cxfws.com/", "SimpleServicePort");

　　Service service = Service.create(wsdlURL, serviceQName);

　　//set handler
　　service.setHandlerResolver(new RequestOrderHandlerResolver());

　　SimpleService port = (SimpleService) service.getPort(portQName, SimpleService.class);

　　//timeout setting
　　Client cl = ClientProxy.getClient(port);

　　HTTPConduit http = (HTTPConduit) cl.getConduit();

　　HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
　　httpClientPolicy.setConnectionTimeout(10000);
　　httpClientPolicy.setReceiveTimeout(1000);
　　http.setClient(httpClientPolicy);
　　System.out.println(port.concatenate("srt1", "srt2"));

　　4,jax-Dispatch,在网上搜索到有人说用以下方式:试了一下不好用.
　　dispatch.getRequestContext().put("com.sun.xml.ws.request.timeout", 1000);
