MethodValidationPostProcessor()
A convenient BeanPostProcessor 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) Target classes with such annotated methods need to be annotated with Spring's Validated annotation at the type level, for their methods to be searched for inline constraint annotations. Validation groups can be specified through @Validated as well. By default, JSR-303 will validate against its default group only.
As of Spring 5.0, this functionality requires a Bean Validation 1.1 provider.
