Axis2創建持久連接

Question

我想要使用.NET製作的web服務。爲了生成我的源代碼，我使用了基於Web服務的WSDL的Axis2。我沒有選擇地推出Axis。

我可以調用webservice的第一個方法。這是Web服務的認證方法「連接」。在此之後，我再次調用一個新方法，但web服務表明我沒有更多的連接。 Web服務的支持告訴我這是因爲在我調用connect方法之後，連接被java關閉。而這個，web服務假設我斷開連接並關閉了會話。

爲了解決這個問題，我的successif調用這兩個方法應該保持在線連接。但是，我不確定Axis2是否提供了這些功能，這是真的嗎？

如何保持不同通話間的連接？

這裏是我的Java代碼：

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，我在我的存根對象上應用的方法，我在線程這個錯誤異常「主」

Answer 1

你有兩個問題正在進行。我不知道爲什麼你沒有連接，但你可以爲高容量請求做一個http連接池。

這裏是談論如何做到這一點Axis2 Blog

而且，這裏是設置一些代碼從Here

編輯更新代碼

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); 
}
