我想从 MULE CE 3.3.0 中的 SOAP Header 获取元素。在流程中，我设置了 WSDLLLocation 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时
http://localhost:9095/MuleLog/Service?wsdl。我在 MULE 控制台中看到了这些错误。
MULE Ce 3.3.0 中的错误，我在浏览器中输入地址后看到这些错误？*
