String[] confs = { "classpath:conf/applicationContext.xml" , "classpath:conf/applicationContext-jdbc.xml" }; ApplicationContext applicationContext = new FileSystemXmlApplicationContext(confs); String[] confs = { "conf/applicationContext.xml" , "conf/applicationContext-jdbc.xml" }; ApplicationContext applicationContext = new ClassPathXmlApplicationContext(confs); ApplicationContext applicationContext = WebApplicationContextUtils.getRequiredWebApplicationContext(ServletContext);
