Intercept transaction only when is sure to be committed but before is committed

Question

Context is Java - JPA with Hibernate and Spring.

Let\'s take the scenario of two-phase commit protocol (but only with one resource):

1. Query to commit fro

Answer 1

Your case is that one of your resource is not compatible with two-phase-commit (not XA-capable). Your idea goes in the direction of the pattern described in paragraph XA and the Last Resource Gambit of http://www.javaworld.com/article/2077963/open-source-tools/distributed-transactions-in-spring--with-and-without-xa.html

The use of the last resource gambit is briefly explained in the answer of How to set up Spring Boot + Bitronix + non-XA Datasource + XA JMS Connection

By the way, your question doesn't mention which implementation of a transaction manager you use (JBossTS, Bitronix JTA, Atomikos Transaction Essentials, ...).
