Bean Validation

Welcome to the Bean Validation specification website. You will find information about the stable version 1.0 as well as version 1.1 currently being worked on.

What is Bean Validation

Bean Validation is a Java specification which:

  • provides a unified way of declaring and defining constraints on an object model.
  • defines a runtime engine to validate objects
public class User {
    @NotNull @Email 
    public String getEmail() { return email; }
    public void setEmail(String email) { 
      this.email = email; 
    }
    private String email;
}
