Apache CXF简单WebService例子

一.开发环境

我的开发环境是：

MyEclipse 6.5

Tomcat 6.0

Apache cxf-2.3.0 下载地址： http://www.apache.org/dist/cxf/2.3.0/

二.开发步骤

创建Server

1. 将下载的cxf-2.3.0 解压。然后在MyEclipse里面添加一个

User Library名字叫library-cxf-2.3.0 把 lib下的包都添加进去。

2.新建一个Web工程cxfdemo，并添加library-cxf-2.3.0,然后建个com.demo包。在包里面创建HelloWorld接口

代码如下

/**
 * HelloWorld.java
 * 版权所有(C) 2010 [e-mail]
 * 创建:崔冉  Dec 2, 2010 9:47:44 AM
 */
package com.demo;

import javax.jws.WebService;

/**
 * @author 崔冉
 * @version 1.0.0
 * @desc 接口HelloWorld
 */
@WebService
public interface HelloWorld {
	String sayHi(String text);
}

再创建一个类实现HelloWorld接口

/**
 * HelloWorldImpl.java
 * 版权所有(C) 2010 [e-mail]
 * 创建:崔冉  Dec 2, 2010 9:49:17 AM
 */
package com.demo;

import javax.jws.WebService;

/**
 * @author 崔冉
 * @version 1.0.0
 * @desc 实现HelloWorld接口
 */
@WebService
public class HelloWorldImpl implements HelloWorld {

	/**
	 * 
	 */
	public String sayHi(String text) {
		
		return "Hi,"+text;
	}

}

然后修改web.xml里面内容

<?xml version="1.0" encoding="UTF-8"?>
<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>/*</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/cxfdemo/HelloWorld" />
    </bean>

</beans>

在创建测试类Client.java

/**
 * Client.java
 * 版权所有(C) 2010 [e-mail]
 * 创建:崔冉  Dec 2, 2010 9:53:30 AM
 */
package com.demo;

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

/**
 * @author 崔冉
 * @version 1.0.0
 * @desc 测试类
 */
public class Client {
	  public static Client self = new Client();
	  private HelloWorld client = null;
	  
	 private Client() {
	        // START SNIPPET: 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;
	    }


	/**
	 * @param args
	 */
	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
