spring为ApplicationContext提供的3种实现分别为:ClassPathXmlApplicationContext,
FileSystemXmlApplicationContext和XmlWebApplicationContext,其中
XmlWebApplicationContext是专为Web工程定制的。使用举例如下:
1. FileSystemXmlApplicationContext

eg1. ApplicationContext ctx = new
FileSystemXmlApplicationContext( "bean.xml" ); //加载单个配置文件 |
eg2. String[] locations = {"bean1.xml", "bean2.xml", "bean3.xml"}; ApplicationContext ctx = new FileSystemXmlApplicationContext(locations ); //加载多个配置文件
eg3. ApplicationContext ctx =new FileSystemXmlApplicationContext("D:roject/bean.xml");//根据具体路径加载文件
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与BeanFactory的xml文件定位方式一样是基于路径的。
3. XmlWebApplicationContext
eg1. ServletContext servletContext = request.getSession().getServletContext(); ApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(servletContext);
