@TransactionScope

@TransactionScope is a specialization of Scope @Scope for a service or component whose lifecycle is bound to the current top-level transaction, within an outer InteractionScope .

Such services should additional implement Spring’s org.springframework.transaction.support.TransactionSynchronization interface, defining the transaction lifecycle callbacks.

Specifically, @TransactionScope is a composed annotation that acts as a shortcut for @Scope("transaction") .

@TransactionScope may be used as a meta-annotation to create custom composed annotations.

Note that (apparently) the org.springframework.transaction.support.TransactionSynchronization infrastructure is only really intended to work with a single org.springframework.transaction.PlatformTransactionManager . And indeed, this is going to be typical case. However, our framework code does at least admit the possibility of multiple org.springframework.transaction.PlatformTransactionManager s being defined in the app. If that is the case, then (I believe) the callbacks of org.springframework.transaction.support.TransactionSynchronization might be called multiple times, once per org.springframework.transaction.PlatformTransactionManager . The framework currently doesn’t provide any way to distinguish between these calls.
