title: Spring - mixing annotation and validator-based validations
body: <p>I've following problem, there's a regular spring model (let's call it "A") with some validations-related annotations. Next, there's a command object (regular POJO class that defines some field, one of them is object of type A). The command object implements Validator interface, to make binding and validation work in controller methods.</p>
  
  <p>Question is, how to make use of annotations-configured validations inside the command object (given it implements Validator interface, hence it has supports() and validate() methods).</p>
  
  <p>What I'm trying to achive is to have basic validations on model that is reused and mixed with some heavier business-logic validations in other parts of the system.</p>
