Apache CXF 是一個開放源代碼框架,提供了用於方便地構建和開發 Web 服務的可靠基礎架構。它容許建立高性能和可擴展的服務,您能夠將這樣的服務部署在 Tomcat 和基於 Spring 的輕量級容器中,以及部署在更高級的服務器上,例如 Jboss、IBM® WebSphere® 或 BEA WebLogic。前端
該框架提供瞭如下功能:java
一 藉助 annotation 建立獨立啓動的web 服務。web

CXF jar包:架構
cxf-2.1.jarapp
以上jar 包 可從apache官方網站下載 apache-cxf-2.1.2.zip, 而後從apache-cxf-2.1.2/lib 目錄中得到
1 首先服務點接口。
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 編寫服務實現
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 編寫 webServiceApp.java類來暴露 web服務。
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 類來啓動服務。 訪問 http://localhost:8080/helloWorld?wsdl 查看是否顯示
wsdl。
5 編寫客戶端訪問服務。
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 測試: run webServiceApp.java 類來啓動服務,而後 run HelloWorldClient.java 來訪問服務。
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: 這裏須要加入 xmlns:jaxws="http://cxf.apache.org/jaxws" 和
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
3 修改客戶端。
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 發佈工程 啓動web服務器(我用 tomcat 6)。
5 訪問 http://localhost:8080/s/webservice/helloWorld?wsdl 查看是否顯示 wsdl 。
6 run run HelloWorldClient.java 來訪問服務。
