/**

 * HelloWorld客戶應用

 *

 *

 * 即：   對於ClassPathXmlApplicationContext（），  classpath:  前綴是不需要的，   默認就是指項目的classpath路徑下面；

 *                            如果要使用絕對路徑，需要加上  file:  前綴表示這是絕對路徑；

 *    

 *       對於FileSystemXmlApplicationContext（），  默認表示的是兩種：

 *    1，沒有盤符的是  項目工作路徑， 即項目的根目錄；

 *    2，有盤符表示的是   文件絕對路徑。

 *   

 *   如果要使用classpath路徑， 需要前綴   classpath:       .

        //用文件系統的路徑

        //  ApplicationContext factory=new FileSystemXmlApplicationContext("src/appcontext.xml");    

      //使用了  classpath:  前綴,作爲標誌,  這樣,FileSystemXmlApplicationContext 也能夠讀入classpath下的相對路徑

      //  ApplicationContext factory=new FileSystemXmlApplicationContext("classpath:appcontext.xml");
