自定义拦截器，验证用户名密码

一、client端

     1、定义一个构造方法：

     

     public AddHeaderInterceptor(String userId, String password){

          super(Phase.PREPARE_SEND);

          this.userId = userId;

          this.password = password;

     }

     2、重写handleMessage

     public void handleMessage(SoapMessage msg) throws Fault {

          List<Header> headers = msg.getHeaders();

          

          Document document = DOMUtils. createDocument();

          Element element = document.createElement("root" );

          

          Element userElement = document.createElement("userName" );

          Element passwordElement = document.createElement("password" );

          

          userElement.setTextContent( userName);

          passwordElement.setTextContent( password);

          

          element.appendChild(userElement);

          element.appendChild(passwordElement);

          

          headers.add( new SoapHeader(new QName("authority" ), element));

     }

     xml为：

     <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

     <soap:Header>

          <root>

               <userName>songchengye</userName>

               <password>123456</password>

          </root>

     </soap:Header>

     <soap:Body>

          <ns2:getMyName xmlns:ns2="http://service.ws.polo.song.com/">

               <arg0>songchengye</arg0>

          </ns2:getMyName>

     </soap:Body>

     </soap:Envelope>

     3、服务器端handleMessage

    public void handleMessage(SoapMessage message) throws Fault {

         List<Header> headers = message.getHeaders();

          if(null ==headers || headers.isEmpty()){

              throw new Fault(new IllegalArgumentException("header is empty." ));

         }

         Header header = headers.get(0);

         Element element = (Element) header.getObject();

         

         NodeList userIds = element.getElementsByTagName("userName" );

         NodeList passwords = element.getElementsByTagName("password" );

         

     if(null == userIds || null == passwords || userIds.getLength() < 1 || passwords.getLength() < 1)     {

              throw new Fault(new IllegalArgumentException("用户名、密码格式不对." ));

         }

         

         String username = userIds.item(0).getTextContent();

         String password = passwords.item(0).getTextContent();

         

          if(null != username && username.equals("songchengye" )

                 && null != password && password.equals("123456" )){

              return;

         } else {

              throw new Fault(new IllegalArgumentException("用户名或密码错误." ));

         }

    }
