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
geronimo-activation_1.1_spec-1.0-M1.jar (or Sun's Activation jar)
geronimo-annotation_1.0_spec-1.1.jar (JSR 250)
geronimo-javamail_1.4_spec-1.0-M1.jar (or Sun's JavaMail jar)
geronimo-servlet_2.5_spec-1.1-M1.jar (or Sun's Servlet jar)
geronimo-ws-metadata_2.0_spec-1.1.1.jar (JSR 181)
jaxb-api-2.1.jar
jaxb-impl-2.1.6.jar
jaxws-api-2.1.jar
jetty-6.1.5.jar
jetty-util-6.1.5.jar
neethi-2.0.jar
saaj-api-1.3.jar
saaj-impl-1.3.jar
stax-api-1.0.1.jar
wsdl4j-1.6.1.jar
wstx-asl-3.2.1.jar
XmlSchema-1.2.jar
xml-resolver-1.2.jar
spring jar 包, 用来支持xml配置:
aopalliance-1.0.jar
spring-core-2.0.4.jar
spring-beans-2.0.4.jar
spring-context-2.0.4.jar
spring-web-2.0.4.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); }
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; } }
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)); } }
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>
<?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]); } }
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。
