Grails Flex Integration, version 1.0
Ever since I discovered Grails, I’ve never stopped looking for the best way to make it work with Flex (I guess for me, the search was NOT over). Why so? Simply because the less time we spend connecting components, mapping objects with the database and dealing with boilerplate code, the more time we have for building gorgeous user interfaces. As for usual web suspects like JSF, GWT, GSP and other HTML/JS-generators, they have never been the best solution for me.
So how do we get Grails and Flex to work together? Well, Grails uses Spring behind the scenes and it is maintained by SpringSource, who also happen to be behind Spring BlazeDS integration in partnership with Adobe. So everything seems to be there… but there’s a problem. The best way to integrate any technology with Grails is via a plugin. Unfortunately the Grails Flex plugin is very old (it does not use Spring BlazeDS integration, but an old custom workaround) and only experimental. There is also a GraniteDS plugin for Grails, but GraniteDS is an alternative to BlazeDS, so it’s not the mainstream way of doing things. And Graeme Rocher has started working on a Spring BlazeDS integration plugin based on the old Flex plugin, but it was never released. Hmmm…
I know, when you’re unhappy with an open source project, when you feel it’s missing something, the better way to help is to do it yourself and share it with the community. But the problem is, although I love using Grails, I’ve never developed a plugin for it before. And this Flex plugin doesn’t seem like an easy one to start with. That’s why I decided to do things differently.
A few months ago, I published an article about Spring, Hibernate, BlazeDS and Flex. This article was very popular, both on my blog and on Adobe Developer Network. But new versions of Maven, Flex and Flexmojos have been released since then, so the article is a little bit outdated now. So why not use this opportunity to do an update?
So here we go. In the following file, there is the full todolist-grails project, that you can also find on GitHub (this is my first Git project by the way). This first version is merely a proof-of-concept. It’s not a plugin, it’s a traditional Grails application with Flex infrastructure added to it. And because I didn’t find a way to integrate Flex compiler with Grails yet, I’m still using IntelliJ Idea to build the Flex part. Still, I’m publishing it as it is because I hope people will help me improve it incrementally.
So if you can help me improve this project and create a Grails plugin out of it in order to automate Flex compilation, integrate Spring Security, generate DTO’s automatically, you’re more than welcome. Let’s get this thing rolling.
