如何在环项目中运行任意启动功能？ [英] How to run an arbitrary startup function in a ring project?

问题描述

我有一个compojure / ring应用程序，我现在运行 lein环服务器，我想编译为.war，所以我可以部署它。我有一个定义，但是，就像

I've got a compojure/ring application I currently run with lein ring server that I'd like to compile to a .war so I can deploy it. I've got a definition, however, just like

 (def foo (start-scheduler))

阻止编译和生成.war。为了避免这种情况，我想到了将调用移动到启动函数，但是当服务器启动时，我该如何调用它？

That blocks the compilation and the generation of the .war. To circumvent this, I thought about moving the call to a startup function, but how would I call it when the server launches?

如果我把调用放在处理程序中，我会遇到和以前一样的问题。

If I put the call inside the handler, I'd end up with the same problem as before.

感谢！

推荐答案

在您的 project.clj 处理程序还可以指定在应用程序启动时运行的init（和destroy）函数：

In your project.clj when declaring your Ring handler you can also specify an init (and destroy) function that is run when your application starts:

:ring {:init myproject.core/init
       :destroy myproject.core/destroy
       :handler myproject.core/handler}

b $ b
