Java Axis2创建持久连接

我想使用.NET中的Web服务。为了生成源代码，我使用了基于web服务WSDL的Axis2。我在没有选择的情况下启动了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，我再次调用了一个新方法，但Web服务表明我不再连接。web服务的支持告诉我这是因为在我调用connect方法之后，连接被java关闭。这样，Web服务假设我断开了连接并关闭了会话

为了解决这个问题，我对这两个方法的successif调用应该在live中保持连接。但是，我不确定Axis2是否建议使用这种功能，是真的吗

如何保持不同通话之间的连接

以下是我的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

如果我遵循答案，我在存根对象上应用方法，我在线程“main”中得到了这个错误异常

你有两个问题要问。我不确定您的应用程序为什么没有连接，但您可以为大量请求创建http连接池

这里有一个博客，讨论如何做到这一点

此外，这里还有一些来自的设置代码

编辑更新代码

Thx，我试过你的解决方案，但我错了。我在另一个答案中写下了错误的信息。对不起，我没有放弃，因为这让我很困扰。若要重用连接，请在调用connect之前调用此连接，因为它用于打开的套接字。我对池的设置有问题，我会解决的。。。stub._getServiceClient（）.getOptions（）.setProperty（org.apache.axis2.transport.http.HTTPConstants.REUSE_http_CLIENT，新布尔值（true））；编辑代码。现在应该可以了。只需记住在调用任何例程之前设置上下文属性。此外，注释中的上述一行将默认为您提供两个连接。
