What I did was extend Main, overriding:
protected AbstractApplicationContext createDefaultApplicationContext();
The overridden method looks like:
@Override
public AbstractApplicationContext createDefaultApplicationContext() {
AbstractApplicationContext appctx =
super.createDefaultApplicationContext();
appctx.addApplicationListener(new
ApplicationListener<ContextStartedEvent>() {
@Override
public void onApplicationEvent(ContextStartedEvent event) {
LOG.info("********** CONTEXT STARTED...");
}});
return appctx;
}
Works for me...
