title: Spring transactions with Objectify and Appengine
body: <p>I am using appengine with Objectify to access my datasource. I use Spring for my business layer. In order to play with data I use the <a href="https://github.com/marceloverdijk/objectify-appengine-spring" rel="nofollow">objectify-appengine-spring factory</a>.</p>
  
  <p>I would like to use annotation based local transactions. Do you know about an existing implementation which I could plug directly as a spring bean?</p>
  
  <p>I'd really like to avoid the pain of implementing my own transaction provider with thread locals.</p>
