How to make my pojos transaction?

Question

I have a multi-threaded multi-server web application with hibernate and spring transaction management with AOP. The problem is that I need to maintain the data in memory and keep it in a state of database state ... essentially I implement a cache in memory.

Now, is there a way to make the my-in-memory pojos transaction at the same level as the / spring sleep transaction? I have service calls with a depth of 30 classes and I never know where the commit will take place. What are my options?

• Thread T2 P, T1 T2, .
• T2 :
  . , T2 P1, T1.
  . commit, T2 P2. T1 P2.
