java - HTTP请求参数消耗:Camel SU问题

下面是Http Camel SU的使用HTTP消息的代码段。您能否告知SMSProcessor组件出了什么问题？

我得到：cannot cast apache.servicemix.jbi.jaxp.StringSource to apache.servicemix.jbi.jaxp.StringSource"

捆绑：

<beans xmlns:http="http://servicemix.apache.org/http/1.0"
       xmlns:b="http://rhinopay.com/bridge">

    <http:consumer service="b:http"
                 endpoint="endpoint"
                 targetService="b:pipeline"
                 locationURI="http://localhost:8192/rhinopay/"
                 defaultMep="http://www.w3.org/2004/08/wsdl/in-out"
                 marshaler="#myMarshaler"
    />

    <bean id="myMarshaler" class="marshaller.HttpMarshaller"/>
</beans>

HttpMarshaller：

import javax.jbi.messaging.MessageExchange;
import javax.jbi.messaging.NormalizedMessage;
import javax.servlet.http.HttpServletRequest;

import org.apache.servicemix.common.EndpointComponentContext;
import org.apache.servicemix.http.endpoints.DefaultHttpConsumerMarshaler;
import org.apache.servicemix.jbi.jaxp.StringSource;

public class HttpMarshaller extends DefaultHttpConsumerMarshaler {

    public MessageExchange createExchange(HttpServletRequest request,
            javax.jbi.component.ComponentContext context) throws Exception {
        // TODO Auto-generated method stub

            String mobile = request.getParameter("mobile");
            String smsTxt = request.getParameter("smsTxt");
         //  String message = request.getParameter("msg");
            MessageExchange exchange = ((EndpointComponentContext) context).getDeliveryChannel().createExchangeFactory().createExchange(getDefaultMep());
            NormalizedMessage in = exchange.createMessage();
            String xmlContext = mobile+","+smsTxt;
            System.out.println("xmlContext---"+xmlContext);
            in.setContent(new StringSource(xmlContext));
            exchange.setMessage(in,"in");
            return exchange;
    }
}

SMSProcessor：

import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.apache.servicemix.jbi.jaxp.StringSource;

public class SMSProcessor implements Processor {

    /*
     * @see org.apache.camel.Processor#process(org.apache.camel.Exchange)
     */
    public void process(Exchange exchange) throws Exception {
        System.out.println("SMSProcessor");
        StringSource text = ((StringSource)exchange.getIn().getBody());
        System.out.println("text"+text.getText());
    }
}

最佳答案

使用Camel类型转换器，而不是Java类型转换

StringSource文本= exchange.getIn（）。getBody（StringSource.class）;

或者，如果您想要纯文本，则可以

字符串文本= exchange.getIn（）。getBody（String.class）;

如果你想要一个DOM

文档dom = exchange.getIn（）。getBody（Document.class）;

等等
