Spring transaction internals

Question

The situation is as follows:

1. Method1 has four database update methods in it. The Method1 is annotated using the Spring transaction management semantics.

Answer 1

Have you read the Spring documentation? Basically AOP is used to manage the transaction. You should also read the AOP documentation. If the AOP documentation is not enough I suggest you go through the code. Stepping through the code in debug mode with break-point would be good.
