Description

An attempt to mirror as much as possible the active record implementation in rails. Some concepts, like intercepted finders, are not possible in Java.

All JDBC operations are performed using Spring's simple JDBC framework. Spring adapters and transaction handling will be implemented as part of the project.

A test suite testing all functionality is provided. A test suite comparing performance of this project to other persistence frameworks will be provided in the future.

Features

Combining data access with the actual data bean
Providing functionality by implementing an interface, not extending a class
Property access by name (getting/setting) as well as java getters/setters
Serialization into JSON to easily transfer records over the wire
Full support for equals/hashCode/toString/clone java functionality
Convention based configuration with fine grained control using annotations
Custom types supported
Basic CRUD operations out of the box (find, count, save, reload, delete)
Dynamic finder methods configured by convention (name) or annotations
Support for native SQL queries and names queries
Transaction support
Spring integration
Before/after interceptors and pre processors - to be implemented
Composite bean building - to be defined and implemented
