Class SpringTransactionManager

java.lang.Object
  org.axonframework.eventhandling.transactionmanagers.SpringTransactionManager

All Implemented Interfaces:

TransactionManager

public class SpringTransactionManager
extends Object
implements TransactionManager

TransactionManager implementation that uses a PlatformTransactionManager as underlying transaction manager.

The transaction manager will commit the transaction when event handling is successful. If a non-transient (non-recoverable) exception occurs, the failing event is discarded and the transaction is committed. If a transient exception occurs, such as a failing connection, the transaction is rolled back and scheduled for a retry.
