In addition to the standard lifecycle annotations @PostConstruct and @PreDestroy, Governator adds: @WarmUp

Methods annotated with @WarmUp will be called in parallel (using the Java Fork-Join framework) when LifecycleManager.start() is called. Object dependencies are respected – i.e. given:

A B C

  • Object A is dependent on objects B and C and all have warm up methods.
  • Object A’s warm up method will not be executed until both objects B and C’s warm up methods complete.
  • Objects B and C’s warm up methods will execute in parallel.

An alternate version of LifecycleManager.start() can be used to limit the amount of time allowed for warm up methods to complete.
