Question

我已按照教程here和here as well创建了一个使用maven和CXF访问WS的客户端。我使用SoapUI多次测试Web服务并收到了结果。但是当我从我的客户端调用相同的Web服务时，我总是得到一个空的响应。在Web服务方面，我观察到响应被正确发送，以防SoapUI和我的客户端应用程序。这是在客户端控制台上打印的内容：

WS init successful. Service class instantiated.
In servlet Calling service now
Action is -- JAX-WS RI 2.1.6 in JDK 6: Stub for http://172.18.40.131:8080/AccountWithCXF/services/AccountSearchActionPort
In servlet after Calling service. list is -> []

有人可以帮帮我吗？

以下是WSDL：

<?xml version='1.0' encoding='UTF-8'?><wsdl:definitions name="AccountSearchActionService" targetNamespace="http://webservice/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://webservice/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

      <wsdl:input name="getAccounts">

      </wsdl:input>
      <wsdl:output name="getAccountsResponse">
        <soap:body use="literal"/>
      </wsdl:output>
    </wsdl:operation>
  </wsdl:binding>
  <wsdl:service name="AccountSearchActionService">

    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

我在servlet

的init（）方法中设置Web服务存根

public void init() throws ServletException {
   super.init();
   service = new AccountSearchActionService();
   System.out.println("WS init successful. Service class instantiated.");
}

来自Servlet的代码片段，它调用Web服务：

AccountSearchAction action = service.getAccountSearchActionPort();
System.out.println("Action is -- "+action);
List<Account> list = action.getAccounts(param);
System.out.println("In servlet after Calling service. list is -> "+list);

如果我使用带有搜索查询'express'的SoapUI调用此Web服务，以下是我得到的响应：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <ns2:getAccountsResponse xmlns:ns2="http://webservice/">
         <ns2:return>
            <accountId>3067822</accountId>
            <accountName>FBB EXPRESS INC.</accountName>
         </ns2:return>
      </ns2:getAccountsResponse>
   </soap:Body>
</soap:Envelope>

Answer 1

调试此方法的最简单方法是捕获请求和响应XML。

这样做的一种方法是发送日志记录拦截器。

另一种方法是使用tcpmon捕获请求/响应和响应。 tcpmon就像一个代理 - 将其设置为侦听某个端口，然后将其转发到原始服务主机：port。使客户端向tcpmon端口发送请求。

CXF Web服务客户端 - 调用Web服务时未收到任何数据
