CXF实现webService服务（一）
对于CXF是干什么用的，我不想多说，大家都知道这是我们在java编程中webService技术的一种实现工具。我们说说为什么用CXF来实现webService：
1. Java的webService实现本身就是一个很耗性能的实现方案（xml与java对象之间在服务端以及客户端的互转比较消耗性能）
2. 目前java主流的webService应用以CXF、AXIS2为主；
3. 通过网络渠道的了解,目前CXF的效率要比AXIS2高出至少50%；
4. 另外有一个webService的工具metro的效率比CXF高出10%；
5. CXF的实现资料网上可以随便找出一大堆，metro的资料相对少一些；
6. CXF在java应用实现中已经很成熟，企业更倾向于用这样一个成熟的解决方案；
基于以上原因，我选择CXF来实现webService。

一 以annotation注解方式实现发布webService应用
1、 基础环境
新建java web工程cxf之后，下载cxf工具包。解压CXF之后，把cxf工具包lib下的jar包全部放到工程的lib下。
此处用到的cxf工具包版本为：apache-cxf-2.7.12
下载地址：
http://www.apache.org/dyn/closer.cgi?path=/cxf/2.7.12/apache-cxf-2.7.12.zip
2、 编写服务接口
[java]
package com.hsy.server;
import java.util.List;
import javax.jws.WebParam;
import javax.jws.WebService;
import com.hsy.pojo.User;
@WebService
public interface HelloWorld {
String sayHi(@WebParam(name="text")String text);
String sayHiToUser(User user);
String[] SayHiToUserList(List<User> userList);
}
3、 服务接口实现
[java]
package com.hsy.server;
import java.util.LinkedHashMap;
import java.util.List;
import java.util.Map;
import javax.jws.WebParam;
import javax.jws.WebService;
import com.hsy.pojo.User;
@WebService(endpointInterface="com.hsy.server.HelloWorld",serviceName="HelloWorld")
public class HelloWorldImpl implements HelloWorld {
Map<Integer, User> users = new LinkedHashMap<Integer, User>();
public String sayHi(@WebParam(name = "text") 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;
}
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
}
}4、 发布服务app
[java]
package com.hsy.server;
import javax.xml.ws.Endpoint;
public class webServiceApp {
/**
* @param args
*/
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");
}
}右键 run as 选择java application发布服务；然后在浏览器输入地址：http://localhost:8080/helloWorld?wsdl
说明webService服务发布成功。
5、 客户端访问服务
[java]
package com.hsy.client;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import com.hsy.pojo.User;
import com.hsy.server.HelloWorld;
public class HelloWorldClient {
/**
* @param args
*/
public static void main(String[] args) {
//首先右键run as 运行com.hsy.server.webServiceApp类，然后再运行这段客户端代码
JaxWsProxyFactoryBean jwpfb = new JaxWsProxyFactoryBean();
jwpfb.setServiceClass(HelloWorld.class);
jwpfb.setAddress("http://localhost:8080/helloWorld");
HelloWorld hw = (HelloWorld) jwpfb.create();
User user = new User();
user.setName("马克思");
user.setDescription("怀念马克思");
System.out.println(hw.sayHiToUser(user));
}
}右键 run as 选择java application，控制台打印如图：
Ok，客户端访问也成功了。
6、 附：
[java]
package com.hsy.pojo;
import java.io.Serializable;
@SuppressWarnings("serial")
public class User implements Serializable {
private String id;
private String name;
private String age;
private String description;
public User() {
super();
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
}
二与spring集成实现webService
1、 配置web.xml
见文件web.xml
[html] <?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>cxf</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.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> <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> <!-- 字符过滤器 --> <filter> <filter-name>encoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>*.jsp</url-pattern> </filter-mapping> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>*.html</url-pattern> </filter-mapping> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>*.do</url-pattern> </filter-mapping> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>*.jsp</url-pattern> </filter-mapping> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>*.html</url-pattern> </filter-mapping> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>*.do</url-pattern> </filter-mapping> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>*.3g</url-pattern> </filter-mapping> </web-app>
2、 配置applicationContext.xml
[html] <?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.hsy.server.HelloWorldImpl" address="/helloWorld" /> <bean id="client" class="com.hsy.server.HelloWorld" factory-bean="clientFactory" factory-method="create"/> <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"> <property name="serviceClass" value="com.hsy.server.HelloWorld"/> <property name="address" value="http://localhost:8080/cxf/webservice/helloWorld"/> </bean> </beans>
3、 修改客户端代码
[java]
package com.hsy.client;
import java.util.ArrayList;
import java.util.List;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.FileSystemResource;
import org.springframework.core.io.Resource;
import com.hsy.pojo.User;
import com.hsy.server.HelloWorld;
public class HelloWorldClient {
/**
* @param args
*/
public static void main(String[] args) {
//Resource resource= new FileSystemResource("F:/workspaces4me2013/.metadata/.me_tcat/WEB-INF/classes/applicationContext.xml");
//BeanFactory factory= new XmlBeanFactory(resource );
ApplicationContext factory = new ClassPathXmlApplicationContext("/applicationContext.xml");
HelloWorld client = (HelloWorld)factory.getBean("client");
User user1 = new User();
user1.setName("马克思");
user1.setDescription("怀念马克思");
User user2 = new User();
user2.setName("恩格斯");
user2.setDescription("怀念恩格斯");
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、 启动tamcat发布webService
然后在浏览器输入地址：http://localhost:8080/cxf/webservice/helloWorld?wsdl
说明webService服务发布成功。
5、 运行客户端代码访问webService
右键 run as 选择java application，控制台打印如图：
Ok，客户端访问也成功了。
此篇实现了webService服务的发布以及在本工程下的客户端调用服务的示例，或许不是很直观。
