数据库表发生更改时更新FrontEnd [英] Updating FrontEnd when there is a Change in Database Table

问题描述

我正在使用JSP，Servlet和MySQL作为数据库来开发应用程序.

I am developing a Application using JSP , Servlets and MySQL as Database .

FrontEnd由DOJO库JavaScript和JSP组成，它显示数据库表中存在的所有元素.

The FrontEnd is made of DOJO library JavaScript and JSP and it displays all the Elements Present in the Database Table .

我们的要求之一是，只要有更改(表中添加了新条目)，它都应立即反映在前端中.

One of our requirement is that whenever there is a change ( A New Entry that is added in the Table) , it should immediately reflect in the Front End .

这不是定期刷新，可能会在1小时2小时甚至5小时后的任何时间发生

This is not a Periodical refresh ,and it may happen at anytime like after 1 Hour 2 Hours or even after 5 Hours )

请推荐处理此要求的最佳方法是什么?

Please sugget what is the best approach to deal with this requirement ??
