JSP中获取spring 容器

JSP中如何获取spring 容器呢?

// 获取spring容器
		ApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(this.getServletContext());
		// 插件数据初始化
		ICommonService commonService = (ICommonService) ctx.getBean("commonService");
		commonService.init();

 

ServletContext context = request.getSession().getServletContext();
		ApplicationContext ctx = WebApplicationContextUtils
				.getWebApplicationContext(context);
