Changes between Bean Validation 2.0 and 1.1

Bean Validation 2.0 focused on the following topics:

  • support for validating container elements by annotating type arguments of parameterized types e.g. List<@Positive Integer> positiveNumbers. This also includes:

    • more flexible cascaded validation of container types

    • support for java.util.Optional

    • support for the property types declared by JavaFX

    • support for custom container types

  • support for the new date/time data types (JSR 310) for @Past and @Future

  • new built-in constraints: @Email, @NotEmpty, @NotBlank, @Positive, @PositiveOrZero, @Negative, @NegativeOrZero, @PastOrPresent and @FutureOrPresent

  • leverage the JDK 8 new features (built-in constraints are marked repeatable, parameter names are retrieved via reflection)
