New features in SpringContracts 0.2

SpringContracts 0.2 is released.

It now supports specification of external contracts without touching the sources by expressing contracts within Spring's ApplicationContext.

Beside Expression Language (EL) as specification language, SpringContracts provides now full out of the box support for OGNL and Groovy. Switching the language is a matter of configuration in Springs Application Context (changing effectively two lines)

Design by Contract for Spring is out

After nearly one year of development, SpringContracts is out and now Open Source.
SpringContracts is a configurable Java solution for Design by Contract, which fits seamlessly into the Spring framework.
For example, SpringContracts allows to configure which parts of a Contract (Pre-, Postcondition, Invariant) should be recognized at runtime and how to react, when Violations occurs (exceptions, logging, ...).
Another pluggable Module is the language, used to describe the single constraints of Pre-, Postconditions and Invariants. While providing a default implementation based on the Expression Language (Commons-EL), there will be the choice to use other Languages like MVEL, OGNL or another Scripting Language (for example Groovy or JRuby) in the next future.
Some minor features include full support (recognition of Contract elements) for deep inheritance and multi-inheritance on interfaces, definition of messages in case of contract violations with reference to it's context (calling method, args, return value) and usage of named constraints (global available common constraints, which can be referenced in any contract by a symbolic name).
