用cxf编纂webservice

用cxf编写webservice
cxf的官网文档地址：http://cxf.apache.org/docs/
1.建立一个web project，名称为cfx-new，部署目录写成ROOT
2.下载最新的cxf包http://cxf.apache.org/download.html，我下载的是apache-cxf-2.5.2.zip，直接将lib下的所有jar拷贝到lib下
3.新建一个接口类HelloWorld

package info.frady.service;

import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface HelloWorld {
    String sayHi(String text);
}

4.建立一个接口的实现类HelloWorldImpl

package info.frady.service.impl;

import info.frady.service.HelloWorld;

import javax.jws.WebService;

@WebService(endpointInterface = "info.frady.service.HelloWorld", 
            serviceName = "helloWorld")
public class HelloWorldImpl implements HelloWorld {
 
    public String sayHi(String text) {
        return "Hello " + text;
    }
}

说明下：
*@WebService：申明为webservice的注解，这样cxf就知道这是个webservice了
*endpointInterface：要暴露的接口类
?*serviceName ：??? 服务名，其实就是调用地址
5.在WEB-INF目录下新建beans.xml，如下：

<?xml version="1.0" encoding="UTF-8"?>
<!-- START SNIPPET: beans -->
<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="info.frady.service.impl.HelloWorldImpl" 
	  address="/helloWorld" />
</beans>

说明：
注： implementor ：接口类的实现类
??????? address：?? 要和注释里面声明的服务名对应，对应的是外部访问地址
6.在修改web.xml文件，如下

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">

<!-- START SNIPPET: webxml -->
<web-app>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/beans.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>/services/*</url-pattern>
	</servlet-mapping>
</web-app>
<!-- END SNIPPET: webxml -->

7.启动tomcat
8.输入地址http://localhost:9081/services/，出现WSDL :?{http://impl.service.frady.info/}HelloWorld说明服务端成功。
9.编写测试代码

import info.frady.domain.Person;
import info.frady.service.HelloWorld;

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;


public class TestHello {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
		factory.getInInterceptors().add(new LoggingInInterceptor());
		factory.getOutInterceptors().add(new LoggingOutInterceptor());
		factory.setServiceClass(HelloWorld.class);
		factory.setAddress("http://localhost:8080/services/HelloWorld");
		HelloWorld client = (HelloWorld) factory.create();
		String reply = client.sayHi("frady");
		System.out.println("Server said: " + reply);	
		System.exit(0); 
	}

}
