lein-non-aot-war

A Leiningen plugin to generate war files that use a non aot compiled servlet.

Usage

Put [lein-non-aot-war "0.1.0"] into the :plugins vector of your :user profile, or if you are on Leiningen 1.x do lein plugin install lein-non-aot-war 0.1.0.

Then, you will need to configure your project.clj file. At a minimum, there must be a :ring map with a ring :handler function and a :resource-scripts map:

:ring {:handler hello-world.core/handler
       :resource-scripts [hello-world/core.clj]}

The following options can be used in the :ring map:

  • :resource-scripts A sequence of scripts that will each be loaded with a call to RT.loadResourceScript. It's important that each separate clj file that is used for your init, destroy, and handler functions is listed here.

  • :init - A function to be called once before your handler starts. It should take no arguments.

  • :destroy - A function called before your handler exits or is unloaded. It should take no arguments.

  • :handler - The ring handler function. This should be a function that takes a request map and returns a response map.

To build an uberwar from the command line:

$ lein non-aot-war

You can be explicit:

$ lein non-aot-war uberwar warfile.war

And generate a skinny war:

$ lein non-aot-war war warfile.war

Approach

The main reasoning behind this approach is to eliminate the long aot compile times when creating a servlet using gen-class. This is done by generating a java servlet implementation that looks up the ring handler at runtime with RT.var.
