//自己: request.getSession().getServletContext().getAttribute("org.springframework.web.context.WebApplicationContext.ROOT") //官方: public class MyInitializer implements ServletContextListener { public void contextDestroyed(ServletContextEvent sce) { // TODO Auto-generated method stub } public void contextInitialized(ServletContextEvent sce) { ApplicationContext ac = WebApplicationContextUtils.getWebApplicationContext(sce.getServletContext()); //sce---ServletContextEvent } }

在web中如:servlet
WebApplicationContext context = ContextLoader.getCurrentWebApplicationContext(); //source public static WebApplicationContext getCurrentWebApplicationContext() { return (WebApplicationContext) currentContextPerThread.get(Thread.currentThread().getContextClassLoader()); }

public class MyApplicationHelper implements ApplicationContextAware { private ApplicationContext applicationContext; public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { this.applicationContext = applicationContext; } public ApplicationContext getApplicationContext(){ return this.applicationContext; } }

ApplicationContext ac = new ClassPathXmlApplicationContext(new String[]{"applicationContext.xml","applicationContext-test.xml"}); ApplicationContext ac = new ClassPathXmlApplicationContext("classpath*:/applicationContext*.xml"); ApplicationContext ac = new ClassPathXmlApplicationContext("classpath*:src/folder/applicationContext*.xml");

ApplicationContext ac = new FileSystemXmlApplicationContext("WebRoot/WEB-INF/applicationContext.xml"); ApplicationContext ac = new FileSystemXmlApplicationContext("file:D:/workspace/testproject/WebRoot/WEB-INF/applicationContext.xml");
