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.
