CXF小例

现在使用的最流行的webservice框架基本上就是Axis,Axis2和Cxf,其实这些框架间这有各的特点，并不能一概而论哪个好，哪个不好，关键是要根据你的系统自身去选择，看哪个更适合于你。

以下是Axis2和Cxf的部分比较：

1.CXF支持WS-Addressing，WS-Policy，WS-RM，WS-Security 和 WS-I 基本规范。Axis2支持除WS-Policy之外的所有协议，WS-Policy也会在即将到来的版本支持。

2.CXF很容易和Spring集成，而Axis2不。

3.Axis2 支持范围更大的数据绑定，包括XMLBeans、JiBX、JaxMe和JaxBRI同时还有它自带的数据绑定方式－－ADB。注意对JaxME和 JaxBRI的支持在Axis2 1.2中仍然处在实验阶段。CXF目前仅支持JAXB和Aegis，对XMLBeans、JiBX和Castor的支持将会在CXF 1.2中实现。

4.Axsi2支持多种语言－－在java版本之外还有C/C++的版本可用。

5.Axis2有利于web services的独立，不依赖其他应用，Cxf可以更好的嵌入到原有系统中，专注于开发者的高效和可嵌入性。

 

服务器端：

 

导入包(jaxws-api-2.0.jar在服务器端不是必须的)：

aopalliance-1.0.jar
commons-logging-1.1.jar
cxf-2.0.2-incubator.jar
geronimo-activation_1.1_spec-1.0-M1.jar
geronimo-annotation_1.0_spec-1.1.jar

新建一个web工程cxf，分别编写接口HelloWorld和其实现类HelloWorldImpl，接口暴露出方法sayHello()供客户端调用(注，必须使用jdk1.5进行编译)：

HelloWorld：

 package  cn.com.service;

 import  javax.jws.WebService;

 @WebService
 public   interface  HelloWorld {

     public  String sayHello(String text);
 }

package cn.com.service;

import javax.jws.WebService;

@WebService
public interface HelloWorld {

	public String sayHello(String text);
}

 

 

 HelloWorldImpl：

 package  cn.com.service;

 import  javax.jws.WebService;

 @WebService (endpointInterface= "cn.com.service.HelloWorld" )
 public   class  HelloWorldImpl  implements  HelloWorld {

     public  String sayHello(String text) {

         return   "Hello"  + text ;
     }

 }

package cn.com.service;

import javax.jws.WebService;

@WebService(endpointInterface="cn.com.service.HelloWorld")
public class HelloWorldImpl implements HelloWorld {

	public String sayHello(String text) {
		
		return "Hello" + text ;
	}

}

 

 

在spring的配置文件spring-bean.xml中配置：

     xmlns:jaxws = "http://cxf.apache.org/jaxws"

     < bean   id = "hello"   class = "cn.com.service.HelloWorldImpl"   />

     < jaxws:endpoint   id = "helloWorld"   implementor = "#hello"
         address = "/HelloWorld"   />

将应用部署到web服务器中(我是部署到tomcat下),可以通过http://localhost:8080/cxf/HelloWorld?wsdl 检测是否发布成功.

 

客户端:

 

导入的包同服务器端相同(只是要将服务器端的接口类打成jar包，方便在客户端调用)

client:

 

 package  cn.com.client;

 import  org.springframework.context.ApplicationContext;
 import  org.springframework.context.support.ClassPathXmlApplicationContext;

 import  cn.com.service.HelloWorld;

 public   class  client {

     public   static   void  main(String[] args) {

         ApplicationContext ctx = new  ClassPathXmlApplicationContext(
                 "spring-bean.xml" );
         HelloWorld client = (HelloWorld) ctx.getBean("client" );
         String result = client.sayHello("你好@@!!" );
         System.out.println(result);
     }
 }
