使用jaxws建立webservice客户端并实现soap消息的handler验证示例

wsimport -keep -extension -s ./src -p com.jaxws.test http://192.168.1.1:8080/service?wsdl

public String jaxws(Object[] opArgs)
{
    ServicesService service=new ServicesService();

    //向SOAP添加表头
    service.setHandlerResolver(new HandlerResolver(){
        public List<Handler> getHandlerChain(PortInfo portInfo) {
            List<Handler> handlerList = new ArrayList<Handler>();
            //添加认证信息
            handlerList.add(new ClientHandler());
            return handlerList;
        }
    });

    String result =service.getServicesPort().getResults(opArgs.toString());
    //得到结果
    System.out.println(result);
    return result;
}
