注：至于获取ServletContext对象，可以从request,session中获取，他们都有getServletContext()方法

ApplicationContext ac1 = WebApplicationContextUtils.getRequiredWebApplicationContext(ServletContext sc)

ApplicationContext ac2 = WebApplicationContextUtils.getWebApplicationContext(ServletContext sc)

UserLogService service = ApplicationContext.getBean(UserLogService.class);
