使用 CXF 做 webservice 简单例子
转:http://www.cnblogs.com/frankliiu-java/articles/1641949.html Apache CXF 是一个开放源代码框架,提供了用于方便地构建和开发 Web 服务的可靠基础架构。它允许创建高性能和可扩展的服务,您可以将这样的服务部署在 Tomcat 和基于 Spring 的轻量级容器中,以及部署在更高级的服务器上,例如 Jboss、IBM? WebSphere? 或 BEA WebLogic。 ? ?????? 该框架提供了以下功能:
????? ?一? 借助 annotation 创建独立启动的web 服务。 ???????准备: 新建工程 导入需要的jar 包: ? ??????????????????依赖的包: ??????????????????????????? commons-logging-1.1.jar ????????????????? spring jar?包, 用来支持xml配置: ??????????????????????????? aopalliance-1.0.jar ?????????????????? CXF jar包: ??????????????????????????? cxf-2.1.jar ??? ?????????以上jar 包 可从apache官方网站下载?apache-cxf-2.1.2.zip, 然后从apache-cxf-2.1.2/lib 目录中获得 ????? 1? 首先服务点接口。 package com.demo; import java.util.List; import javax.jws.WebParam; import javax.jws.WebService; @WebService public interface HelloWorld { String sayHi(@WebParam(name="text")String text); String sayHiToUser(User user); String[] SayHiToUserList(List<User> userList); } · ? ? 2? 编写服务实现 package com.demo; import java.util.LinkedHashMap; import java.util.List; import java.util.Map; import javax.jws.WebService; @WebService(endpointInterface="com.demo.HelloWorld",serviceName="HelloWorld") public class HelloWorldImpl implements HelloWorld { Map<Integer,User> users = new LinkedHashMap<Integer,User>(); public String sayHi(String text) { return "Hello " + text; } public String sayHiToUser(User user) { users.put(users.size()+1,user); return "Hello "+ user.getName(); } public String[] SayHiToUserList(List<User> userList) { String[] result = new String[userList.size()]; int i=0; for(User u:userList){ result[i] = "Hello " + u.getName(); i++; } return result; } } ?3? 编写 webServiceApp.java类来暴露 web服务。 package com.demo; import javax.xml.ws.Endpoint; public class webServiceApp { public static void main(String[] args) { System.out.println("web service start"); HelloWorldImpl implementor= new HelloWorldImpl(); String address="http://localhost:8080/helloWorld"; Endpoint.publish(address,implementor); System.out.println("web service started"); } } 4? run webServiceApp.java 类来启动服务。 访问?http://localhost:8080/helloWorld?wsdl? 查看是否显示 ???? wsdl。 ?5??编写客户端访问服务。 package com.demo; import java.util.ArrayList; import java.util.List; import org.apache.cxf.jaxws.JaxWsProxyFactoryBean; import org.springframework.context.support.ClassPathXmlApplicationContext; public class HelloWorldClient { public static void main(String[] args) { JaxWsProxyFactoryBean svr = new JaxWsProxyFactoryBean(); svr.setServiceClass(HelloWorld.class); svr.setAddress("http://localhost:8080/helloWorld"); HelloWorld hw = (HelloWorld) svr.create(); User user = new User(); user.setName("Tony"); user.setDescription("test"); System.out.println(hw.sayHiToUser(user)); } } ?6??测试: run webServiceApp.java 类来启动服务,然后 run HelloWorldClient.java 来访问服务。 ?二 集成到spring 中。 1 在 web.xml 中加入 : <?xml version="1.0" encoding="UTF-8"?> <web-app> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>contextConfigLocation</param-name> <param-value>WEB-INF/classes/applicationContext.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <servlet> <servlet-name>CXFServlet</servlet-name> <display-name>CXFServlet</display-name> <servlet-class> org.apache.cxf.transport.servlet.CXFServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>CXFServlet</servlet-name> <url-pattern>/webservice/*</url-pattern> </servlet-mapping> </web-app> 2? 在 applicationContext.xml 中加入: <?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"/> <jaxws:endpoint id="helloWorld" implementor="com.demo.HelloWorldImpl" address="/helloWorld" /> <bean id="client" class="com.demo.HelloWorld" factory-bean="clientFactory" factory-method="create"/> <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"> <property name="serviceClass" value="com.demo.HelloWorld"/> <property name="address" value="http://localhost:8080/s/webservice/helloWorld"/> </bean> </beans> 注意: 这里需要加入 ?xmlns:jaxws="http://cxf.apache.org/jaxws"???和 ??????????????http://cxf.apache.org/jaxws?http://cxf.apache.org/schemas/jaxws.xsd ?3? 修改客户端。package com.demo; import java.util.ArrayList; import java.util.List; import org.apache.cxf.jaxws.JaxWsProxyFactoryBean; import org.springframework.context.support.ClassPathXmlApplicationContext; public class HelloWorldClient { public static void main(String[] args) { HelloWorld client = (HelloWorld)context.getBean("client"); User user1 = new User(); user1.setName("Tony"); user1.setDescription("test"); User user2 = new User(); user2.setName("freeman"); user2.setDescription("test"); List<User> userList= new ArrayList<User>(); userList.add(user1); userList.add(user2); String[] res = client.SayHiToUserList(userList); System.out.println(res[0]); System.out.println(res[1]); } } ?4? 发布工程?启动web服务器(我用 tomcat 6)。 5?访问?http://localhost:8080/s/webservice/helloWorld?wsdl??查看是否显示 wsdl 。 ?6??run run HelloWorldClient.java 来访问服务。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
