CXF學習總結2 添加攔截器+整合Spring

1.自訂攔截器

package com.cxf.interceptor;import java.util.List;import javax.xml.soap.SOAPException;import org.apache.cxf.binding.soap.SoapMessage;import org.apache.cxf.headers.Header;import org.apache.cxf.interceptor.Fault;import org.apache.cxf.phase.AbstractPhaseInterceptor;import org.apache.cxf.phase.Phase;import org.apache.log4j.Logger;import org.w3c.dom.Element;import org.w3c.dom.NodeList;//AbstractPhaseInterceptor可以指定攔截器在那個階段起作用public class UserInterceptor extends AbstractPhaseInterceptor<SoapMessage> {Logger logger=Logger.getLogger(UserInterceptor.class);//顯示調用父類的有參數的構造器就不會在隱示調用父類無參構造器public UserInterceptor() {super(Phase.PRE_INVOKE);//在調用之前攔截soap訊息}@Override//message就是被攔截到的訊息public void handleMessage(SoapMessage msg) throws Fault {//擷取所有的頭元素List<Header> headers=msg.getHeaders();if(headers==null || headers.size()==0){throw new Fault(new SOAPException("缺少Head 元素"));}//擷取第一個頭元素(w3c.dom.Element)Header firstHead= headers.get(0);Element element= (Element) firstHead.getObject();NodeList nameList= element.getElementsByTagName("userName");NodeList passWordList= element.getElementsByTagName("passWord");if(nameList.getLength()!=1 || passWordList.getLength()!=1){throw new Fault(new SOAPException("使用者名稱密碼格式有問題"));}//擷取使用者名稱密碼String userName=nameList.item(0).getTextContent();String passWord=passWordList.item(0).getTextContent();logger.info(userName+":"+passWord);if(! userName.equals("rain") ||  ! passWord.equals("rain"))throw new Fault(new IllegalArgumentException("使用者名稱密錯誤"));}}

 

2.Web.Xml設定檔

<?xml version="1.0" encoding="UTF-8"?><web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"><display-name></display-name><!-- Spring設定檔 --><context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/config/context/*.xml</param-value></context-param><!-- Spring監聽 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- CXFServlet 的訪問地址--><servlet><servlet-name>CXFServlet</servlet-name><servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class></servlet><servlet-mapping><servlet-name>CXFServlet</servlet-name><url-pattern>/WebService/*</url-pattern></servlet-mapping><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>

 

3.Spring設定檔

xmlns:jaxws="http://cxf.apache.org/jaxws" 可以看到cxf下定義的標籤

 

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://cxf.apache.org/jaxwshttp://cxf.apache.org/schemas/jaxws.xsd"><import resource="classpath:META-INF/cxf/cxf.xml" /><import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /><import resource="classpath:META-INF/cxf/cxf-servlet.xml" /><!-- Service --><bean id="UserServiceImpl" class="com.cxf.service.impl.UserServiceImp"></bean><!-- WebService --><bean id="UserServiceWs" class="com.cxf.ws.impl.UserServiceWs"><property name="userService" ref="UserServiceImpl"></property></bean><!-- 攔截器 --><bean id="userInterceptor" class="com.cxf.interceptor.UserInterceptor"/><!-- 發布的地址，實現的介面，實作類別 ，攔截器--><jaxws:server id="userManager" address="/userManager" serviceClass="com.cxf.ws.IUserServiceWs" ><jaxws:serviceBean><ref bean="UserServiceWs"/></jaxws:serviceBean><jaxws:inInterceptors> <ref bean="userInterceptor"/> </jaxws:inInterceptors></jaxws:server></beans>
