any experience with “Play” java web development framework? [closed]

Answer 1

I currently build web applications at work using play framework which does massive data processing. I must say that the speed that play offers alone is significant and more than what RoR can provide. Besides, play is a java based framework and hence Multi-Threading can be done easily. Next is the sheer performance you get when you use java-based modules like Japid and Netty along with play.It's like an endless amount of tweaking can be done for performance. A must try in my opinion.

Answer 2

I like the look of Play, but haven't tried it. From scanning through the docs one thing that stood out was the heavy use of static methods. From a unit testing point of view this always makes things much harder (I'm thinking mocks), and is a departure from the OO-everywhere approach in typical Java development. Maybe this is the point, but it's just something that made me a little less enthused...

Answer 3

I've tried Play and I'm impressed: it does a great job of delivering a useful development model that is far simpler than most frameworks'. More than anything else, the runtime's ability in 'development mode' to parse .java files directly is worth a lot: just reloading the web page in the browser without running a build script or waiting for a redeployment is worth a lot of development speed. The error messages shown in the browser are really good too.

Another thing that impressed me was the overall aesthetic: it is perhaps a small thing that the tutorial application actually looks good (both the code and the web page design), but this extends to the whole framework, the API as well as the documentation.

After prodding from a colleague I looked at it, followed the tutorial, and got hooked. Getting immediate feedback right in your browser means you don't have to use an IDE. I love Eclipse, but let's face it: after you've added some extras, it's not as stable as a simple text editor. On a Mac with TextMate you can even click on the error message in your browser and TextMate pops up with the cursor on that line.

Testing in Play is also nicely done, with one button press you run unit tests, functional tests and Selenium-based tests.

Play is exciting because it's still small and uncomplicated. It uses just ant to build and does so in 25 seconds. Contributing to the beautiful documentation is a matter of editing the .textile files and reloading the docs in any play app.

That's how I wound up on a quest to translate the tutorial to use Scala, adding to the Scala support where needed to get it as nice as possible.

Answer 5

I've used Grails, Tapestry 4/5 and straight Java/JSP/Spring/Hibernate.

I think this is going in the right direction for the first time in a long time. Grails was a really good first step but Play! looks like something that could really have legs. Scala support is coming in 1.1. If there is a chance I can write my controllers/domain in Clojure, I'm sold ;)

Answer 6

I'm using Play in a small project, and seems to be exactly what they've said about. But one feature I think should to be present by default in the framework: ability to work with more than one datasource (e.g. use more than one database schema). This is the only missing feature I've found until now.
