在MULE CE 3.3.0中使用cxf-interceptor从SOAP Header获取元素

时间：2013-04-13 07:02:02

标签： web-services soap cxf mule interceptor

我想在MULE CE 3.3.0中从SOAP Header获取元素。 在流程中，我设置了WSDLLocation和我的自定义java类。

这是我在下面复制它们的流程代码：

<http:inbound-endpoint host="localhost" port="9095" 
    path="MuleLog/Service" exchange-pattern="request-response">
<custom-processor class="com.example.processors.SOAPHeaderExtractor" /> 
    <cxf:proxy-service wsdlLocation="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
        namespace="http://ws.cdyne.com/WeatherWS/" service="Weather" >
        <cxf:inInterceptors  >
            <spring:bean id="inLogger" class="org.apache.cxf.interceptor.LoggingInInterceptor" />   
        </cxf:inInterceptors>   
    </cxf:proxy-service>        
</http:inbound-endpoint>

 <http:outbound-endpoint address="http://wsf.cdyne.com/WeatherWS/Weather.asmx">
 </http:outbound-endpoint>

这是我的SOAPHeaderExtractor类：

        package com.example.processors;


    import javax.xml.soap.MessageFactory;
    import javax.xml.soap.SOAPHeader;
    import javax.xml.soap.SOAPMessage;

    import org.mule.api.MuleEvent;
    import org.mule.api.MuleMessage;
    import org.mule.api.processor.MessageProcessor;

    public class SOAPHeaderExtractor implements MessageProcessor {

        @Override
        public MuleEvent process(MuleEvent event) {     
            try
            {
                MuleMessage inputMessage =  event.getMessage(); 
                SOAPMessage soapMsg = MessageFactory.newInstance().createMessage(null, 
                        new java.io.ByteArrayInputStream(inputMessage.getPayloadAsString().getBytes()));
                 SOAPHeader header = soapMsg.getSOAPHeader();            
                 System.out.println(header.getElementsByTagName("sampler").item(0).getTextContent() );
            }
            catch(Exception e){
                e.printStackTrace();            
            }       
            return event ;
        }
    }
  • 但是当我运行它并输入地址http://localhost:9095/MuleLog/Service?wsdl时。我在MULE控制台中看到了这些错误。

MULE Ce 3.3.0中的错误，我在浏览器中输入了地址后看到了这些错误？*
