CXF+Spring+Tomcat简明示例

多系统（异构系统）进行交互时，一种良好的方式便是调用Web Service，本示例基于Apache组织的CXF，为了方便起见特将服务端和客户端写在同一个工程下，

实际项目中是不可能的，但是客户端却依赖于服务端的Web Service接口，那么可以通过导出jar的方式。

环境：
MyEclipse10
JDK6
Tomcat7
CXF2.5
Spring3

示例项目结构图：


如上图所示，全部依赖的第三方库都在lib中，下面贴出全部代码。
IHelloService.java

package bing.server;

import javax.jws.WebService;

/** *//**
* <p>
* WebService接口
* </p>
*
*@author IceWee
* @date 2012-7-6
*@version 1.0
*/
@WebService
publicinterface IHelloService{

   public String sayHello(String username);
   
}

HelloServiceImpl.java

package bing.server;

import javax.jws.WebService;

/** *//**
* <p>
* WebService实现类
* </p>
*
*@author IceWee
* @date 2012-7-6
*@version 1.0
*/
@WebService(endpointInterface="bing.server.IHelloService", serviceName="HelloService")
publicclass HelloServiceImplimplements IHelloService{

    @Override
   public String sayHello(String username){
       return"hello, "+ username;
    }

}

HelloServiceClient.java

package bing.client;

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

import bing.server.IHelloService;

/** *//**
* <p>
* WebService调用方-客户端
* </p>
*
*@author IceWee
* @date 2012-7-6
*@version 1.0
*/
publicclass HelloServiceClient{

   publicstatic void main(String[] args){
        ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext-client.xml");
        IHelloService helloService= (IHelloService) context.getBean("client");
        String response= helloService.sayHello("Peter");
        System.out.println(response);
    }

}

所有项目都已配置完成，可以发布到Tomcat了，在浏览器中输入：http://localhost:8080/CXFDemo/ws，返回如图：


从上图中可以看到我们对外发布的WebService接口，点击蓝色超链接，返回如图：

到此，证明我们的Web Service已经发布成功，可以进行调用测试了。运行HelloServiceClient，返回如图：

全文完！

《注解》：

<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" />

这几个xml在cxf-xxx.jar包里面。

HelloServiceImpl 类的注解：
@WebService(endpointInterface = "bind.server.IHelloService", serviceName = "helloService")

注意：serviceName 是小写开头的helloService否则出错

@Override 时出错误：The method **() of type must override  a supertclass method

解决办法是：

一、                                                                     
因为你的Compiler 是jdk1.5，只要把它改为 1.6

方法： 

1. window ->preferences... -> java -> Compiler

2. Compiler compliance level : 6.0

二、 把项目的JRE变成6.0的
项目右键->build path->configure build path->java Compiler(左边那排中) ->在右边的Compiler compliance level 修改版本为1.6
