WebService如果涉及到安全保密或者使用权限的时候，WS-Security通常是最优选择。WS-Security (Web服务安全)
包含了关于如何在WebService消息上保证完整性和机密性的规约，如何将签名和加密头加入SOAP消息。
不过WS-Security也有一些性能上的损耗，在信息保密要求不是很高的情况下，可以通过在SOAPHeader中添加简单的校验信息实现。
具体思路是客户端调用需要认证的服务时，在SOAPHeader中添加授权信息（如用户名、密码或者序列号等）。
服务端收到请求，在SOAPHeader中校验授权信息，校验通过则执行请求，校验不通过则返回错误提示。

客户端发起请求在SOAPHeader中添加的授权数据格式如下

<authxmlns="http://schemas.xmlsoap.org/soap/actor/next">  <username>admin</username>  <password>admin</password>
</auth>

客户端发起请求

QName SERVICE_NAME = new QName("http://tempuri.org/", "aexampleDemoWebService");
URL url= new URL("http://localhost:8090/service/Sample?wsdl");
AexampleDemoWebServiceSoap ss= newAexampleDemoWebServiceSoap(wsdlURL, SERVICE_NAME);
AExampleDemoWebService port=ss.getSample();
port.querySingle("1111");

@HandlerChain 注解 替代方式

　　客户端  通过 HandlerReolver 代替 @HandlerChain 注解 导入 Handler 配置文件

　　handler-chain配置文件对所有的请求都添加授权验证信息，有些时候不是所有的请求都需要添加授权验证，HandlerResolver提供了在编程时添加Handler的方法，可以用HandlerResolver给需要授权的接口添加Handler。

QName SERVICE_NAME = new QName("http://tempuri.org/", "aexampleDemoWebService");
URL url= new URL("http://localhost:8090/service/Sample?wsdl");
AexampleDemoWebServiceSoap ss= newAexampleDemoWebServiceSoap(wsdlURL, SERVICE_NAME);//通过HandlerResolver添加Handler
ss.setHandlerResolver(newHandlerResolver(){  @Override  @SuppressWarnings("rawtypes")public List<Handler>getHandlerChain(PortInfo portInfo) {  List<Handler> handlerChain = new ArrayList<Handler>();  handlerChain.add(newJaxWsClientHandler());returnhandlerChain;  }  });
AExampleDemoWebService port=ss.getSample();
port.querySingle("2222");

服务端 @HandlerChain 注解替代

　　服务发布时服务端通过继承至 Endpoint 实现类 EndpointImpl 的 setHandlers 方法添加头部信息 代替 @HandlerChain 注解 导入 Handler 配置文件

importjava.util.ArrayList;importjava.util.List;importjavax.xml.ws.Endpoint;importjavax.xml.ws.handler.Handler;importorg.apache.cxf.Bus;importorg.apache.cxf.bus.spring.SpringBus;importorg.apache.cxf.interceptor.Interceptor;importorg.apache.cxf.jaxws.EndpointImpl;importorg.apache.cxf.message.Message;importorg.apache.cxf.transport.servlet.CXFServlet;importorg.springframework.boot.context.embedded.ServletRegistrationBean;importorg.springframework.context.annotation.Bean;importorg.springframework.context.annotation.Configuration;@Configurationpublic classCXFConfig {@BeanpublicServletRegistrationBean dispatcherServlet() {return new ServletRegistrationBean(new CXFServlet(), "/service/*");}@Bean(name=Bus.DEFAULT_BUS_ID)publicSpringBus springBus() {return newSpringBus();}@BeanpublicAExampleDemoWebServiceImpl aExampleDemoWebServiceImpl() {return newAExampleDemoWebServiceImpl();}@BeanpublicEndpoint endpointWebServiceSampleImpl() {EndpointImpl endpoint= newEndpointImpl(springBus(), aExampleDemoWebServiceImpl());//SOAPHandler 方式@SuppressWarnings("rawtypes")List<Handler> handlers = new ArrayList<>();handlers.add(newJaxServerAuthValidateHeader());endpoint.setHandlers(handlers);endpoint.publish("/Sample");returnendpoint;}}

当使用替代方式添加头部信息的时候就不需要使用 @HandlerChain 注解
