To integrate Flex with Java on server you need to have a server framework like BlazeDS or LCDS (or any other third party equivalent remoting framework) and you will have to use one of the Flex's data access methods to access data such as HttpService, WebService or RemoteObject etc.
...there are bunch of ready event based frameworks available like Cairngorm which is owned by Adobe itself. Its worth taking a look at choosing a flex framework.
I am working on java-flex since last few months and one problem I am facing is session tracking. I am still yet to find the best solution for this. Second problem faced too common is memory leaks when using too many popup screens. But overall I think it may be one of the popular future architectures.

Does that mean you are stuck with the framework listed out here or is it open enough to integrate with Spring or any other framework? Looks like too many options. There is no one way to do things right?

I think you are missunderstanding where the framework is used. Spring in a Flex application doesn't make any sense. Spring with a Flex application does. The frameworks listed are frameworks for writing just the Flex component (though there is nothing to stop you using their patterns in other layers of your application).
