Heavy load on spring controller?

Question

What happen even many request comes through one spring controller? Does Spring pipe it? How about add @Transactinal on controller? Is it have a benefit to use on controller layer?

La solution

Basically you are asking 2 questions

  1. How are multiple, concurrent, requests handled by a handler.
  2. Should we add @Transactional to a handler.

Multiple concurrent requests are handled concurrently. Each thread has its own callstack and location in memory and doesn't share a thing. In general no problem (used Spring MVC in very high concurrent applications) unless you start, for some reason, sharing state in your singleton, or forget to clean-up ThreadLocals.

Adding @Transactional is something bad, IMHO. The transactional layer is NOT your web but your service layer. So don't add transactions to your web but add them to your service layer.
