从使用Play框架1.X的GAE上的Siena到使用Play 2.0的Heroku上的哪个数据库/ api /模块？

Question

I've really enjoyed using Play framework 1.X on Google App Engine with Siena for data storing.

Now I'm looking into using Play framework 2.0 for a new project. As Play isn't ready for GAE I'm going to try out Heroku. What are my options if I want the simplicity of annotating my classes like with Siena and having them stored in some NoSQL database at Heroku? Can I use the built in data storage support in Play or are there any modules that support some NoSQL addon at Heroku?

Edit:

I want to use Play's Java API (not Scala).

Answer 1

With Play 1.2.X you could use the " MongoLab " add-on to Heroku together with the Morphia Play module .

As for Play2, I would suggest checking out the " salat " plugin to access your MongoDB's. See https://github.com/zenexity/Zest for an example play2 app using salat. Good luck!

Answer 2

If your models are not too specific to GAE, you can switch to postgres quite easily with Siena. It's one of its main purpose ;)
