多系統(tǒng)(異構系統(tǒng))進行交互時,一種良好的方式便是調用Web Service,本示例基于Apache組織的CXF,為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,但是客戶端卻依賴于服務端的Web Service接口,那么可以通過導出jar的方式。

所有項目都已配置完成,可以發(fā)布到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(fā)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(jīng)發(fā)布成功,可以進行調用測試了。運行HelloServiceClient,返回如圖:

全文完!
