Web Service学习-CXF与Spring整合为JavaEE应用发布WebService(三)

来源:互联网 发布:java转义字符 & 编辑:程序博客网 时间:2024/05/22 12:47

CXFSpring整合,分两个方面给大家介绍:

 

1,在传统ssh项目基础上添加Web Service

赋值CXFjar

web.xml配置文件中导入CXF的核心控制器:CXFServlet

Spring配置文件中导入CXF提供Schemaxml配置文件

Spring配置文件中使用jaxws:endpoint元素来暴露Web Service

如果要添加拦截器,在jaxws:endpoint元素里添加

inInterceptors,outInterceptors子元素

2,远程调用Web Service服务(让Action依赖远程Web Service的接口)

复制CXFjar

Spring配置文件中导入CXF提供Schemaxml配置文件

Spring配置文件中使用jaxws:client元素来配置远程Web Service代理

如果要添加拦截器。在jaxws:client元素里添加

inInterceptors,outInterceptors子元素

 

第一个方面:提供Web Service的服务


服务端:

 

项目结构:




在相应的SSH项目中添加CXF的相关jar包:




Web.xml


<?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"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"version="2.5"><listener>          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>      </listener>        <context-param>          <param-name>contextConfigLocation</param-name>          <param-value>/WEB-INF/applicationContext-common.xml</param-value>      </context-param>        <!--所有来自/*的请求,都交由 CXFServlet来处理-->    <servlet>          <servlet-name>HelloWorldService</servlet-name>          <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>          <load-on-startup>1</load-on-startup>      </servlet>      <servlet-mapping>          <servlet-name>HelloWorldService</servlet-name>          <url-pattern>/*</url-pattern>      </servlet-mapping>     </web-app>

applicationContext-common.xml:


<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:jaxws="http://cxf.apache.org/jaxws"      xsi:schemaLocation="  http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  http://cxf.apache.org/jaxws http://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" />        <bean id="helloWorld" class="com.tgb.service.impl.HelloWorldImpl">    <property name="userService" ref="userService"></property>    </bean>      <!-- 用户的Service -->        <bean id="userService" class="com.tgb.service.impl.UserServiceImpl">           </bean><!-- implementor指定webservice的服务提供者 --><!-- address为wsdl的访问地址 -->    <jaxws:endpoint id="hello" implementor="#helloWorld" address="/hjy" ><!-- 添加了2个In拦截器,如果不添加拦截器可直接注释掉如下代码 --><jaxws:inInterceptors><bean class="org.apache.cxf.interceptor.LoggingInInterceptor"/><bean class="com.tgb.auth.AuthInterceptor"/></jaxws:inInterceptors><!-- 如果要配置Out拦截器,使用outInterceptors --></jaxws:endpoint></beans>

以上配置已经完成,对于接口和相应的实现参考之前的博客即可,实现中对于new的内容使用spring管理起来

 

HelloWorldImpl:

package com.tgb.service.impl;import java.util.Date;import java.util.List;import java.util.Map;import javax.jws.WebService;import com.tgb.domain.Cat;import com.tgb.domain.User;import com.tgb.service.HelloWorld;import com.tgb.service.UserService;@WebService(endpointInterface="com.tgb.service.HelloWorld",serviceName="HelloWorldImpl")public class HelloWorldImpl implements HelloWorld{private UserService userService;public UserService getUserService() {return userService;}public void setUserService(UserService userService) {this.userService = userService;}public String sayHi(String name) {return name+"您好!现在时间为:"+new Date();}@Overridepublic List<Cat> getCatsByUser(User user) {//在实际项目中,web service组件自己并不会去实现业务功能//它只是调用业务逻辑组件的方法来暴露web service//UserService us=new UserServiceImpl();return userService.getCatsByUser(user);}@Overridepublic Map<String, Cat> getAllCats() {//UserService us=new UserServiceImpl();return userService.getAllCats();}}

启动tomcat服务器:

新建客户端项目CXF_Spring_Client,生成客户端代码:




注意:

有些版本拷贝后,类中的super()会出错,要加上-frontendjaxws21,参看如上截图

 

客户端调用:


package com.tgb.client;import java.util.List;import org.apache.cxf.endpoint.Client;import org.apache.cxf.frontend.ClientProxy;import com.tgb.auth.AddHeaderInterceptor;import com.tgb.service.Cat;import com.tgb.service.HelloWorld;import com.tgb.service.User;import com.tgb.service.impl.HelloWorldImpl;public class client {public static void main(String[] args){HelloWorldImpl factory=new HelloWorldImpl();//此处返回的只是远程Web Service的代理HelloWorld hw=factory.getHelloWorldImplPort();/** * 添加的拦截器 */Client client=ClientProxy.getClient(hw);//参数为输入的用户名,密码client.getOutInterceptors().add(new AddHeaderInterceptor("hejingyuan","hjy"));System.out.println(hw.sayHi("hejingyuan"));System.out.println("--------------------------");User user=new User();user.setId(20);user.setName("孙悟空");user.setPass("111");user.setAddress("花果山");List<Cat> cats=hw.getCatsByUser(user);for(Cat cat:cats){System.out.println(cat.getName());}System.out.println("--------------------------");System.out.println(hw.getAllCats().getEntry().get(0).getKey());System.out.println(hw.getAllCats().getEntry().get(0).getValue().getName());}}



由于我们在服务端添加了拦截器,故客户端必须要添加相应的拦截器给服务端提供参数,否则客户端调用失败




另一个方面:调用远程的Web Service服务

 

新建客户端项目CXF_Spring_Web_Client,生成客户端代码




web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" 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_2_5.xsd"><context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/applicationContext.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><filter><filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class></filter><filter-mapping><filter-name>struts2</filter-name><url-pattern>/*</url-pattern></filter-mapping>    </web-app>

applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:jaxws="http://cxf.apache.org/jaxws"      xsi:schemaLocation="  http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  http://cxf.apache.org/jaxws http://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" /><bean id="listCatsAction" class="com.tgb.action.ListCatsAction"><property name="helloWorld" ref="helloWorld"></property></bean>  <!-- 配置远程webservice代理 --><!-- id="helloWorld"对应 action setHelloWorld() --><jaxws:client id="helloWorld"serviceClass="com.tgb.service.HelloWorld"address="http://localhost:8080/CXF_Spring_Server/hjy"><jaxws:outInterceptors><!-- 配置输出拦截器  --> <bean class="com.tgb.auth.AddHeaderInterceptor" ><constructor-arg value="hejingyuan"/><constructor-arg value="hjy"/></bean></jaxws:outInterceptors></jaxws:client></beans>

Struts.xml


<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"><struts><package name="default" namespace="/" extends="struts-default"><action name="listCats" class="com.tgb.action.ListCatsAction" ><result name="SUCCESS">/WEB-INF/page/listcats.jsp</result></action></package></struts>    

调用代码:

package com.tgb.action;import org.apache.cxf.endpoint.Client;import org.apache.cxf.frontend.ClientProxy;import com.opensymphony.xwork2.ActionSupport;import com.tgb.auth.AddHeaderInterceptor;import com.tgb.service.HelloWorld;public class ListCatsAction extends ActionSupport{private HelloWorld helloWorld;public HelloWorld getHelloWorld() {return helloWorld;}public void setHelloWorld(HelloWorld helloWorld) {this.helloWorld = helloWorld;}@Overridepublic String execute() throws Exception {/** * 添加的拦截器 */Client client=ClientProxy.getClient(helloWorld);//参数为输入的用户名,密码client.getOutInterceptors().add(new AddHeaderInterceptor("hejingyuan","hjy"));helloWorld.sayHi("hejingyuan");return "SUCCESS";}}

最终的项目结构:




总结:


     以上与Spring的整合,概括的说,在应用Spring的框架过程中,一种是我们如何对外提供服务,另一种是我们如何获取已经提供好的服务。在整个过程中,只有几个关键点,很简单,但是要注意jar包的版本问题。
