CXF学习-与Spring整合（暴露web Service接口给其他程序使用）

基本步骤：

1、保证服务一启动就加载Spring；

2、在web-xml中配置CXF的核心配置；

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xmlns="http://java.sun.com/xml/ns/javaee"     xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"     id="WebApp_ID" version="2.5">  <display-name/>  <listener>      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>  <context-param>      <param-name>contextConfigLocation</param-name>      <param-value>/WEB-INF/classes/applicationContext.xml</param-value>  </context-param>    <!-- 配置CXF -->  <!-- 下面的配置说明凡是请求路径为/studyCXF/*均交给CXFServlet处理 -->  <servlet>      <servlet-name>CXFServlet</servlet-name>      <!-- CXF核心配置：org.apache.cxf.transport.servlet.CXFServlet -->      <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>  </servlet>  <servlet-mapping>      <servlet-name>CXFServlet</servlet-name>      <url-pattern>/studyCXF/*</url-pattern>  </servlet-mapping>    <welcome-file-list>    <welcome-file>index.html</welcome-file>    <welcome-file>index.htm</welcome-file>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list></web-app>

3、在Spring配置文件中导入CXF提供Schema、xml配置；

<beansxmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xmlns:p="http://www.springframework.org/schema/p"xmlns:jaxws="http://cxf.apache.org/jaxws"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.1.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-3.1.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-3.1.xsdhttp://cxf.apache.org/jaxwshttp://cxf.apache.org/schemas/jaxws.xsd"><!-- 先写命名空间，再写具体路径 --><!-- web类加载路径：两类 webRoot下面的class以及lib路径下面的jar文件 --><import resource="classpath:/META-INF/cxf/cxf.xml"/><import resource="classpath:/META-INF/cxf/cxf-servlet.xml"/><import resource="classpath:/META-INF/cxf/cxf-extension-soap.xml"/></beans>

4、在Spring配置文件中，使用jaxws：endpoint 来暴露webService;

5、如果要添加拦截器，在jaxws：endpoint里面添加inInterceptors及outInterceptors元素。

 <!-- implementor提供者-->    <!-- 设置为以i个bean前面加#号 --><jaxws:endpoint address="/fkjava" implementor="#helloWorldWS">    <!-- 添加拦截器 -->    <jaxws:inInterceptors>        <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"></bean>        <bean class="cxf.ws.auth.AuthInInterceptor"></bean>    </jaxws:inInterceptors>    </jaxws:endpoint>

拦截器

package cxf.ws.auth;import java.util.List;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.w3c.dom.Element;import org.w3c.dom.NodeList;//通过AbstractPhaseInterceptor决定拦截器在哪里起作用public class AuthInInterceptor extends AbstractPhaseInterceptor<SoapMessage> {public AuthInInterceptor(){//显示调用父类有参构造器super(Phase.PRE_INVOKE);}//实现自己的拦截器，需要实现handleMessage方法//handleMessage方法的形参SoapMessage就是拦截到的SOAP消息//一旦获取了SOAP消息，就可以解析或修改SOAP消息@Overridepublic void handleMessage(SoapMessage msg) throws Fault {System.out.println("-----------------------------");//得到消息的所有headerList<Header> headers=msg.getHeaders();if(headers==null||headers.size()<1){throw new Fault(new IllegalArgumentException("Header为空"));}Header firstHeader=headers.get(0);Element ele=(Element) firstHeader.getObject();NodeList userIds=ele.getElementsByTagName("userId");NodeList userPasss=ele.getElementsByTagName("userPass");if(userIds.getLength()<1){throw new Fault(new IllegalArgumentException("用户名格式不对"));}if(userPasss.getLength()<1){throw new Fault(new IllegalArgumentException("密码格式不对"));}String userId=userIds.item(0).getTextContent();String userPass=userPasss.item(0).getTextContent();if(!(userId.equals("Charles")&&userPass.equals("duyx5218"))){throw new Fault(new IllegalArgumentException("用户名、密码不匹配"));}}}
