记录一次webservice添加拦截器，来达到修改xml报文的目的
import org.apache.cxf.endpoint.Client;import org.apache.cxf.frontend.ClientProxy; private ?Soap createSoap() { ???????service = new Service(); ???????soap = service.getServiceSoap(); ???????//拦截器改造报文头 ???????client = ClientProxy.getClient(soap); ???????HeaderInInterceptor soapHeaderInInterceptor = new HeaderInInterceptor(); ???????soapHeaderInInterceptor.setHostUser("username", "password"); ???????client.getOutInterceptors().add(soapHeaderInInterceptor); ???????return soap; ???}public class HeaderInInterceptor extends AbstractSoapInterceptor { ???public HeaderInInterceptor() { ???????super(Phase.WRITE); ???} ???private String msg; ???@Override ???public void handleMessage(SoapMessage message) throws Fault { ???????try { ???????????List<Header> headers = message.getHeaders(); ???????????QName qName = new QName("Authorization-My-Header");//需要增加的节点 ???????????Document document = careteDocument(msg); ???????????Element documentElement = document.getDocumentElement(); ???????????SoapHeader head = new SoapHeader(qName, documentElement); ???????????headers.add(head); ???????} catch (Exception e) { ???????????e.printStackTrace(); ???????} ???} ???public void setHostUser(String username,String pw) { ???????String ?str = "<tem:AuthorizationSoapHeader soapenv:mustUnderstand=\"1\" xmlns:tem=\"http://tempuri.org/\" " ???????????+ "xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" ???????????+ "\t<tem:UserName>"+ username+"</tem:UserName>\n" ???????????+ "\t<tem:Password>"+pw+"</tem:Password>\n" ???????????+ "</tem:AuthorizationSoapHeader>"; ???????this.msg = str; ???} ???public static Document careteDocument(String xml) throws Exception { ???????InputStream strm ; ???????strm = new ByteArrayInputStream(xml.getBytes("UTF-8")); ???????DocumentBuilderFactory domFactory = DocumentBuilderFactory ???????????.newInstance(); ???????domFactory.setNamespaceAware(true); ???????DocumentBuilder builder = domFactory.newDocumentBuilder(); ???????Document doc = builder.parse(strm); ???????return doc; ???}}ps：一般来说，使用 “wsimport -clientjar {xxx.jar} -p {包名} -s {源码包名} {url}” 生成的客户端中，创建service都有无参和有参的方法
无参：每次去调用远端的URL来生成service
有参：将wsdl放在本地，通过url传入该方法，即可减少每次请求的网络开销
service = new Service(new URL("file://xxx/xxx.wsdl"));webservice之拦截器
