Multi-threaded Context initialization with spring?

Question

I have a traditional 3-tier application with spring. One of my repositories needs > 3 minutes for initialization so I thought about some multi-threaded approach in order to speed up the whole process - I think most service and controllers in my dependency tree can already be started so only a few must wait for the last repository to come up.

Is there any best practice approach?

Use Spring's Executor abstraction. And if you are within a app server then I suggest you use application server's work-manager (spring supports it). For e.g. WebSphere app server and Weblogic both support registering the workmanagers in JNDI. You can then pass the jndi name to spring. Task Executors
