使用new ClassPathXmlApplicationContext("applicationContext.xml"); 来读取时，将applicationContext.xml放到/WEB-INF/classes目录下；
或放到src目录下，

// ClassPathXmlApplicationContext 是读取 src 目录下的配置文件
ApplicationContext app = new ClassPathXmlApplicationContext("applicationContext.xml");

//  FileSystemXmlApplicationContext 即系统文件路径，文件的目录。
ApplicationContext context = new FileSystemXmlApplicationContext("WebRoot/WEB-INF/applicationContext.xml");
