使用 tomcat manager app 优于 copy-to-webapp 目录的优点

我最近一直在思考，为什么要使用tomcat manager来部署/取消部署wars到你的服务器?

I have been pondering a lot lately over, why should one use tomcat manager to deploy/undeploy wars to your server?

与简单地将其复制到 webapps-folder 方法和从 webpass-folder 删除它的方法相比，相同的优点/缺点是什么??

What are the advantages/disadvantages of the same over simply copy-it-to-webapps-folder approach, and delete-it-from-webpass-folder approach??

此外，当删除战争时，tomcat 的清理过程是否还有其他优势?即清理过程是否不同，当开发人员删除 .war 时，以及当他使用管理器取消部署 web 应用程序时??

Also, are there any other advantages regarding cleanup process by tomcat , when a war is deleted? i.e is the process of cleanup different, when a dev deletes a .war , and when he undeploys a webapp using the manager??

另外，如果我将 ant 与 TCD 一起使用，过程会有所不同吗?

Also, would the process be different If I use ant with TCD?

对此有所了解会非常有帮助.

Some light on this would be really helpful.
