启动SSM项目时自动执行方法

一定要扫描这个工具类，否则是不会生效的，因为有注解

    /**

     * @param contextRefreshedEvent
     */
    @Override
    public void onApplicationEvent(ContextRefreshedEvent contextRefreshedEvent) {
        if (ROOT.equals(contextRefreshedEvent.getApplicationContext().getDisplayName())) {
            //获取容器,读取核心配置类
            ClassPathXmlApplicationContext classPathXmlApplicationContext=new ClassPathXmlApplicationContext("spring/ApplicationContext.xml");
            //获取你要操作的类和类的方法
            //1、获得initController的bean
            InitController initController=(InitController) classPathXmlApplicationContext.getBean("initController");
            //2、执行初始化的方法
            initController.init();
        }
    }
