It's not clear what your requirements are.

The Spring Batch project provides a BatchMessageListenerContainer.

Message listener container adapted for intercepting the message reception with advice provided through configuration. To enable batching of messages in a single transaction, use the TransactionInterceptor and the RepeatOperationsInterceptor in the advice chain (with or without a transaction manager set in the base class). Instead of receiving a single message and processing it, the container will then use a RepeatOperations to receive multiple messages in the same thread. Use with a RepeatOperations and a transaction interceptor. If the transaction interceptor uses XA then use an XA connection factory, or else the TransactionAwareConnectionFactoryProxy to synchronize the JMS session with the ongoing transaction (opening up the possibility of duplicate messages after a failure). In the latter case you will not need to provide a transaction manager in the base class - it only gets on the way and prevents the JMS session from synchronizing with the database transaction.
