CXF+Spring+Tomcat简明示例

http://yufenfei.iteye.com/blog/1685242

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;

/**

 * WebService接口
 * </p>

 * @date 2012-7-6
 * @version 1.0
 */
@WebService
public  interface IHelloService  {

    public String sayHello(String username);
    
}

HelloServiceImpl.java

package bing.server;

import javax.jws.WebService;

/**

@WebService(endpointInterface = "bing.server.IHelloService", serviceName = "HelloService")
public  class HelloServiceImpl  implements IHelloService  {

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

}

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：
