public class MethodValidationInterceptor
extends java.lang.Object
MethodInterceptor implementation that delegates to a
JSR-303 provider for performing method-level validation on annotated methods.
Applicable methods have JSR-303 constraint annotations on their parameters and/or on their return value (in the latter case specified at the method level, typically as inline annotation).
E.g.: public @NotNull Object myValidMethod(@NotNull String arg1, @Max(10) int arg2)
Validation groups can be specified through Spring's Validated annotation
at the type level of the containing target class, applying to all public service methods
of that class. By default, JSR-303 will validate against its default group only.
As of Spring 4.0, this functionality requires either a Bean Validation 1.1 provider (such as Hibernate Validator 5.x) or the Bean Validation 1.0 API with Hibernate Validator 4.3. The actual provider will be autodetected and automatically adapted.
