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
geronimo-javamail_1.4_spec-1.0-M1.jar
geronimo-servlet_2.5_spec-1.1-M1.jar
geronimo-ws-metadata_2.0_spec-1.1.1.jar
jaxb-api-2.0.jar
jaxb-impl-2.0.5.jar
jaxws-api-2.0.jar
neethi-2.0.2.jar
saaj-api-1.3.jar
saaj-impl-1.3.jar
spring-beans-2.0.4.jar
spring-context-2.0.4.jar
spring-core-2.0.4.jar
spring-web-2.0.4.jar
stax-api-1.0.1.jar
wsdl4j-1.6.1.jar
wstx-asl-3.2.1.jar
xml-resolver-1.2.jar
XmlSchema-1.2.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)：

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 ;
	}

}

在spring的配置文件spring-bean.xml中配置：

<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" />

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

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

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
	http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-bean.xml</param-value>
	</context-param>

	<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>
	
	<servlet>
		<servlet-name>CXFServlet</servlet-name>
		<display-name>CXF Servlet</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>/*</url-pattern>
	</servlet-mapping>
</web-app>

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);
	}
}

spring-bean.xml:

<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" />

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

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