??? spring為ApplicationContext提供的3種實現分別為：ClassPathXmlApplicationContext，FileSystemXmlApplicationContext和XmlWebApplicationContext，其中XmlWebApplicationContext是專為Web工程定制的。使用舉例如下：
??
?1. FileSystemXmlApplicationContext?????? eg1. ApplicationContext ctx = new FileSystemXmlApplicationContext("bean.xml"); //加載單個配置文件
?????? eg2.
?????????????? String[] locations = {"bean1.xml", "bean2.xml", "bean3.xml"};
???????????????ApplicationContext ctx = new FileSystemXmlApplicationContext(locations ); //加載單個配置文件
???????eg3.????
??? ApplicationContext ctx =new FileSystemXmlApplicationContext("D:/project/bean.xml");//根據具體路徑加載文件
? 2. ClassPathXmlApplicationContext
???????eg1.??ApplicationContext ctx = new ClassPathXmlApplicationContext("bean.xml");
???????eg2.
?????????????? String[] locations = {"bean1.xml", "bean2.xml", "bean3.xml"};
?????????????? ApplicationContext ctx = new ClassPathXmlApplication(locations);
?????? 注：其中FileSystemXmlApplicationContext和ClassPathXmlApplicationContext與BeanFactory的xml文件定位方式一樣是基于路徑的。
?3. XmlWebApplicationContext
???eg1. ServletContext?servletContext =?request.getSession().getServletContext();????
??????? ApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(servletContext);
