Very simple implementation of TransactionAttributeSource which will always return
the same TransactionAttribute for all methods fed to it. The TransactionAttribute
may be specified, but will otherwise default to PROPAGATION_REQUIRED. This may be
used in the cases where you want to use the same transaction attribute with all
methods being handled by a transaction interceptor.

setTransactionAttribute(TransactionAttribute transactionAttribute) Allows a transaction attribute to be specified, using the String form, for
