org.springframework.data.transaction

Class ChainedTransactionManager

java.lang.Object

org.springframework.data.transaction.ChainedTransactionManager

All Implemented Interfaces:

org.springframework.transaction.PlatformTransactionManager

public class ChainedTransactionManager
extends Object
implements org.springframework.transaction.PlatformTransactionManager

PlatformTransactionManager implementation that orchestrates transaction creation, commits and rollbacks to a list of delegates. Using this implementation assumes that errors causing a transaction rollback will usually happen before the transaction completion or during the commit of the most inner PlatformTransactionManager.

The configured instances will start transactions in the order given and commit/rollback in reverse order, which means the PlatformTransactionManager most likely to break the transaction should be the last in the list configured. A PlatformTransactionManager throwing an exception during commit will automatically cause the remaining transaction managers to roll back instead of committing.

1.6
