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
JDK7
Tomcat7
CXF2.8
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


public interface IHelloService {




    public String sayHello(String 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：
