How to use the embedded java code to get the beans defined in the spring configuration file in the JSP page?

For example, a test.jsp page, the user directly requests the page,
Need to get spring's applicationContext.xml in this page
Defined bean, how to do it?
You cannot use the new ClassPathXmlApplicationContext () method in the page, as this will cause
The bean has been initialized repeatedly. Thank you in advance!

context = (ApplicationContext) getServletContext().getAttribute(
                ContextLoaderPlugIn.SERVLET_CONTEXT_PREFIX);
        logger.info("The count of definition Bean in the application is :"
                + context.getBeanDefinitionCount());
        //Get the data source connected to the sybase database
        //DataSource ds = (DataSource) context.getBean("applicationds1");
        //Store the obtained sybase data source in a static variable
        //LoadCodesServlet.sybaseDS = ds;
        //Get the injected session factory class and get a connection to the database through the factory
        SessionFactory sessionFactory = (SessionFactory) context.getBean("sessionFactory");


So you can get it.
