Java Validation Frameworks

问题:

I once came across a validation framework for java, where you wrote one method that protected the integrity of the data-type and any CRUD operations on that data-type automatically called this method.

Does anyone know what this framework is? I simply want to avoid repetitive validation on every CRUD method attached to a data-type.
