Is there an implementation of the ActiveRecord pattern in Java like the one from Ruby? [closed]

Answer 1

I discover the scooter framework which is based on AR, with built-in Ajax functions and pure Java and Jsp and code generator, it's wonderful of simplicity and efficacity !!

Answer 2

Check out ActiveObjects, a more Rails-esque ActiveRecord then the other mappers: https://activeobjects.dev.java.net/

Answer 3

Hibernate is an ORM framework in Java and based on JPA specifications. JPA (Java Persistent API) internally implements ActiveRecord Pattern at number of places. But overall JPA is based on bit complex pattern called as DataMapper.

You can refer to this Active Record Pattern paper for comparison between Rails ActiveRecord and Hibernate

Answer 4

I released this ActiveJDBC project: http://javalite.io/activejdbc

This is an implementation of ActiveRecord in Java

Answer 5

You could also consider using ActiveRecord-JDBC running on JRuby: http://wiki.jruby.org/wiki/ActiveRecord-JDBC

I haven't done that myself, but I have had great success in using ActiveRecord's Migrations to manage schema migrations in a Hibernate based application.

Answer 6

There is a nice implementation in the play framework using JPA. Maybe it can be used solo...
