在部署WAR时如何调用Java方法

How to call a Java method while deploying a WAR

推荐答案

目前尚不清楚您所说的部署"是什么意思.是WAR文件到达应用服务器的那一刻吗?也许您与Ant玩了些杜松子酒.是在应用启动时吗?也许您可以使用 ServletContextListener 来做到这一点.

It's not clear what you mean by "deploy". Is that the moment when the WAR file arrives on the app server? Maybe you gin something up with Ant. Is that when the app starts up? Maybe you can do it with a ServletContextListener.

在我所知道的任何Java EE应用服务器中都没有内置这样做的机制，因此如果Ant不适合，您将不走运.您需要进行部署的事情才能为您完成.

There's no mechanism for doing so built into any Java EE app server I know of, so you're out of luck if Ant isn't suitable. You need something that does the deploying to do it for you.

您这样做的目的是什么?这种方法有什么用?

What's your purpose for doing so? What does this method do?
