Transactions In MongoDB

I am using a NoSQL database MongoDB with Java and Spring Data. I am aware that MongoDB only supports transactions for a single document.

I am using Spring Transactions to carry out MongoDB transcations. I am using TransactionTemplate. What should I set in TransactionManager when using TransactionTemplate?

EDIT

I have something like this:

<bean id=”txtTemplateBean” class=”org.springframework.transaction.support.TransactionTemplate”>
<property name=”transactionManager” ref=”txnManagerBean”></property>

I need to define txnManagerBean to point to something like DataSourceTransactionManager for a MongoDB database.
