开发笔记:spring定时器中如何获取servletcontext

@Scheduled(cron = "0 0 */3 * * ?") // 3小时处理一次
public void updateData(){
System.out.println("*********************************schedule task");
WebApplicationContext webApplicationContext = ContextLoader.getCurrentWebApplicationContext();
ServletContext context = webApplicationContext.getServletContext();
List tblList = tblMapper.getAll();
context.setAttribute("tbl", tblList);

}
