上一节介绍了怎么用camel和cxf去起一个webservice，这节介绍怎么用camel去调用其它系统的webservice。

请看blueprint.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"
           xmlns:camel-cxf="http://camel.apache.org/schema/blueprint/cxf" 
           xmlns:cxfcore="http://cxf.apache.org/blueprint/core" 
           xsi:schemaLocation="

	<camelContext  id="myCamelContext" xmlns="http://camel.apache.org/schema/blueprint" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                   xsi:schemaLocation="http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd">
        <route>
            <from uri="<span style="font-family: Arial, Helvetica, sans-serif;">vm:_WGTest</span>"/>
            <to uri="cxf:http://192.168.1.100:8081/test?wsdlURL=http://192.168.1.100:8081/test?wsdl&dataFormat=RAW"/>           
        </route>
    </camelContext>
	
 
    <bean id="gwrequest" class="com.cn.yyc.GWRequest">
        <property name="camelcontext" ref="myCamelContext"/>
    </bean>
</blueprint>	

下面是com.cn.yyc.GWRequest

public class GWRequest{
    private static final Logger log = LoggerFactory.getLogger(GWRequest.class);
    private CamelContext camelcontext;
	public void setCamelcontext(CamelContext camelcontext) {
        this.camelcontext = camelcontext;
    }

    @EndpointInject(uri = "vm:_WGTest")
    private ProducerTemplate producer;


    private String invoke(String xml){
        Exchange exch = camelcontext.getEndpoint("vm:_WGTest").createExchange();
        exch.setPattern(ExchangePattern.OutIn);
        exch.getIn().setHeader("SOAPAction", "\"\"");
        exch.getIn().setBody(xml);//报文内容
        producer.send("vm:_WGTest", exch);
        return exch.getOut().getBody(String.class);
    }
}
