测试
public static void main(String[] args) throws SQLException, LoginException{ ApplicationContext atx = new FileSystemXmlApplicationContext("WEB-INF/applicationContext.xml"); AddLoginMessage addmsg =(AddLoginMessage) atx.getBean("proxy"); addmsg.setMessage("this is a login test"); System.out.println(addmsg.getMessage()); }
