下午遇到一个问题，在开发时，HTML修改后浏览器刷新始终不显示修改后的效果。经过朋友的指导，原来是要选择Exploded包进行部署。如图所示。
在Intellij的官方文档上如此描述：To have the application deployed as a directory, choose Web Application: Exploded.To have the application deployed in the packed form, choose Web Application: Archive.大意是如果想以目录形式部署，选择Exploded(adj. 爆炸了的；分解的；被破除的)模式,如果想以打包模式部署，则选择Archive模式。Exploded模式带来的好处是支持热部署，这样不用在开发过程中每次修改了内容后(HTML\JSP)都重新部署，重启一次大概要1-3分钟，有此可见大大提高了开发效率。缺点是多次部署后，Tomcat可能内存溢出，此时就必须重启Tomcat。
