18.7. 如何让 camel-cxf 响应以 xml 处理指令开头

Error:sendSms: SoapFault exception: [Client] looks like we got no XML document in [...]

public class WriteXmlDeclarationInterceptor extends AbstractPhaseInterceptor<SoapMessage> {
    public WriteXmlDeclarationInterceptor() {
        super(Phase.PRE_STREAM);
        addBefore(StaxOutInterceptor.class.getName());
    }

    public void handleMessage(SoapMessage message) throws Fault {
        message.put("org.apache.cxf.stax.force-start-document", Boolean.TRUE);
    }

}

 // set up the response context which force start document
 Map<String, Object> map = new HashMap<String, Object>();
 map.put("org.apache.cxf.stax.force-start-document", Boolean.TRUE);
 exchange.getOut().setHeader(Client.RESPONSE_CONTEXT, map);
