**一.开发环境**

我的开发环境是：

MyEclipse 10

Tomcat 6.0

Apache cxf-2.3.0 相关jar包下载地址： [ http://www.apache.org/dist/cxf/2.3.0/][http_www.apache.org_dist_cxf_2.3.0]

**二.开发步骤**

**创建Server**

**1.**新建一个Web工程WebServiceDemo，并添加apache-cxf-2.3.0相关jar文件,然后建个com.demo包。在包里面创建HelloWorld接口

代码如下

package com.demo;
    
    import javax.jws.WebMethod;
    import javax.jws.WebParam;
    import javax.jws.WebResult;
    import javax.jws.WebService;
    
    @WebService  
    public interface HelloWorld {
    	@WebMethod
    	@WebResult String sayHi(@WebParam String text);  
    
    }

再创建一个类实现HelloWorld接口

package com.demo;
    
    import javax.jws.WebService;
    
    @WebService
    public class HelloWorldImpl implements HelloWorld {
    
    	public String sayHi(String text) {
    		// TODO Auto-generated method stub
    		return "Hi," + text;
    
    	}
    
    }

然后修改web.xml里面内容

<?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5" 
    	xmlns="http://java.sun.com/xml/ns/javaee" 
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
      <display-name></display-name>	
      <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
      </welcome-file-list>
      
        <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>       
            <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>

在WEB-INF下面创建一个beans.xml

代码如下

<?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" />
    </beans>

将Web工程发布到Tomcat里面，然后启动Server

**创建Client**

接着创建客户端，在com.demo下面创建client-beans.xml。内容如下

<?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/schema/jaxws.xsd">
    
        <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://127.0.0.1:8080/WebServiceDemo/HelloWorld" />
        </bean>
    
    </beans>

在创建测试类Client.java

package com.demo;
    
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    public class Client {
    	public static Client self = new Client();
    	private HelloWorld client = null;
    
    	private Client() {
    		ApplicationContext context = new ClassPathXmlApplicationContext(
    				new String[] { "com/demo/client-beans.xml" });
    		client = (HelloWorld) context.getBean("client");
    
    	}
    
    	public HelloWorld getServer() {
    		return client;
    
    	}
    
    	public String getText(String text) throws Exception {
    		String response = getServer().sayHi(text);
    		return response;
    	}
    
    	public static void main(String[] args) {
    		// TODO Auto-generated method stub
    		try {
    
    			System.out.println(self.getText("cuiran"));
    		} catch (Exception e) {
    			// TODO Auto-generated catch block
    			e.printStackTrace();
    		}
    	}
    
    }

然后进行测试运行。如果遇到类似这种错误“AXB 2.1 API is being loaded from the bootstrap classloader”说明你的web工程添加了J2EE 1.4或者是1.5 library. 这样就与jaxb-api-2.2.1.jar

冲突了，只需删除即可。

最后运行如图
