Nested Transaction using Spring and Hibernate

In my app, there are m开发者_JS百科ultiple steps where many commits to the database will be made sequentially through multiple methods. Example:

A -> B -> C
       -> D
           ->E
       -> F
  -> G

A calls B which calls C. Then B calls D. D calls E and so on. All of these methods have some database operations. As I understand from PROPAGATION_REQUIRED (declarative transaction management - the spring recommended way), if E completes successfully, the transaction (and operations in E will be committed). Now, due to some exception, F should lead to a rollback. I want to have everything rolled-back starting from what A did. Is this possible via Declarative Transaction management? Or should I use Programmatic Transaction Management?

Thank you.

First, "nested" transactions, in the sense that there are multiple running transactions depending on each other, is not supported, afaik.

Then, propagation=REQUIRED means that all methods with that propagation will:

• start a new transaction if there is none exists
• participate in an existing transaction if such exists.

This means that in your scenario, a failure in F would rollback the entire transaction (because it is a single transaction, started by A, and propagated to other methods)
