Question

我想使用.NET制作的web服务。为了生成我的源代码，我使用了基于Web服务的WSDL的Axis2。我没有选择就推出了Axis。

我可以调用webservice的第一个方法。这是Web服务的身份验证方法“Connect”。在此之后，我再次调用一个新方法，但是webservice表明我没有更多连接。 Web服务的支持告诉我，因为在我调用connect方法之后，连接被java关闭。而且，web服务假设我已断开连接并关闭我的会话。

要解决这个问题，我对两种方法的成功调用应该保持实时连接。但是，我不确定Axis2是否提出了这些功能，这是真的吗？

如何保持不同来电之间的联系？

这是我的java代码：

WinbooksWebServiceStub stub = new WinbooksWebServiceStub("http://myUrl/Service.asmx");
Connect c = new Connect();
c.setKey("KEY");
c.setUser("USER");
c.setPass("PSW");

ConnectResponse resp = stub.connect(c);
ConnectParser connecterParser = new ConnectParser();//works and return the Token

HelloWorld h = new HelloWorld();
HelloWorldResponse Hresp = stub.helloWorld(h); //the result tell me that I'm not connected

如果我按照答案，我在我的存根对象上应用方法，我在线程“main”中得到此错误异常

你有两个问题。我不确定为什么你没有连接，但你可以为高容量请求做一个http连接池。

以下是一篇博客，介绍了如何执行此操作Axis2 Blog

此外，以下是Here

设置的一些代码

编辑更新代码

import org.apache.axis2.client.Stub;
import org.apache.axis2.context.ConfigurationContext;
import org.apache.axis2.transport.http.HTTPConstants;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.MultiThreadedHttpConnectionManager;
import org.apache.commons.httpclient.params.HttpConnectionManagerParams;

public static void setContextProperties(Stub stub) {

    // Set the max connections to 20 and the timeout to 20 seconds
    MultiThreadedHttpConnectionManager multiThreadedHttpConnectionManager = new MultiThreadedHttpConnectionManager();

    HttpConnectionManagerParams params = new HttpConnectionManagerParams();
    params.setDefaultMaxConnectionsPerHost(20);
    params.setMaxTotalConnections(20);
    params.setSoTimeout(20000);
    params.setConnectionTimeout(20000);
    multiThreadedHttpConnectionManager.setParams(params);

    HttpClient httpClient = new HttpClient(multiThreadedHttpConnectionManager);

    stub._getServiceClient().getServiceContext().getConfigurationContext().setProperty(HTTPConstants.CACHED_HTTP_CLIENT, httpClient);
}

Axis2创建持久连接
