Rails like database abstraction for Java

I have recently been using rails for a web application, and so I have grown to quite like the way it makes dealing with a database very simple through Active Re开发者_如何学Ccord. I am, therefore, wondering if there are any Java libraries that would make it equally simple to deal with the database by hiding away issue of writing SQL?

Have you taken a look at: activejdbc? It's an implementation of the Active Record pattern in Java, and obviously inspired by RoR.

Hibernate is an excellent ORM that generally serves this purpose:

You can build things like GenericDAOs that allow you to easily manage all objects the same way:

so that you can get basic CRUD capabilities very quickly for anything in your model, but still allows you to configure business logic particular DAO as needed.

1. Grails
2. Spring ROO
3. Play Framework

Are 3 java application frameworks who seem to share some similar scaffolding capabilities that was popularized with Rails.

there is also ActiveWeb - a Rails-like Java web framework: http://code.google.com/p/activeweb/
