Spring transactions with Objectify and Appengine

I am using appengine with Objectify to access my data source. I use Spring for my business level. To play with data, I use objectify-appengine-spring factory .

I would like to use local transactions based on annotations. Do you know about an existing implementation that I could connect directly as a Spring bean?

I would really like to avoid the pain of implementing my own transaction provider with thread locations.

Check LushLife ObjectifyTransactionManager here or here .

Spring XML ( ):

<!-- ObjectifyManager -->
<bean id="objectifyManager" class="ex.objectify.spring.ObjectifyManager">
        <property name="basePackage" value="gso.model" />
</bean>

<!-- ObjectifyFactoryBean -->
<bean id="objectifyFactory" class="ex.objectify.spring.ObjectifyFactoryBean">
        <property name="manager" ref="objectifyManager" />
</bean>

<!-- Custom TransactionManager implementation -->
<bean id="transactionManager" class="ex.objectify.spring.ObjectifyTransactionManager">
        <property name="manager" ref="objectifyManager" />
</bean>

<!-- Necesary to enable use of @Transactional in your services -->
<tx:annotation-driven />

@Transactional.
