CXF+Spring+Tomcat簡明示例

多系統（異構系統）進行交互時，一種良好的方式便是調用Web Service，本示例基於Apache組織的CXF，爲了方便起見特將服務端和客戶端寫在同一個工程下，實際項目中是不可能的，但是客戶端卻依賴於服務端的Web Service接口，那麼可以通過導出jar的方式。

環境：
MyEclipse10
JDK6
Tomcat7
CXF2.5
Spring3

示例項目結構圖：


如上圖所示，全部依賴的第三方庫都在lib中，下面貼出全部代碼。
IHelloService.java

package bing.server;

所有項目都已配置完成，可以發佈到Tomcat了，在瀏覽器中輸入：http://localhost:8080/CXFDemo/ws，返回如圖：


從上圖中可以看到我們對外發布的WebService接口，點擊藍色超鏈接，返回如圖：

到此，證明我們的Web Service已經發布成功，可以進行調用測試了。運行HelloServiceClient，返回如圖：
