public class BeanValidationInterceptor<T extends Message<?>> extends Object implements MessageHandlerInterceptor<T>, MessageDispatchInterceptor<T>
Messages. When validation on a message fails, a
JSR303ViolationException is thrown, holding the constraint violations. This interceptor can either be used as
a MessageHandlerInterceptor or as a MessageDispatchInterceptor.| Constructor and Description |

The interceptor is responsible for the continuation of the handling process by invoking the InterceptorChain.proceed() method on the given interceptorChain.
The given unitOfWork contains contextual information. Any information gathered by interceptors
may be attached to the unitOfWork.
Interceptors are highly recommended not to change the type of the message handling result, as the dispatching
component might expect a result of a specific type.handle in interface MessageHandlerInterceptor<T extends Message<?>>unitOfWork - The UnitOfWork that is processing the messageinterceptorChain - The interceptor chain that allows this interceptor to proceed the dispatch processException - any exception that occurs while handling the message@Nonnull public BiFunction<Integer,T,T> handle(@Nonnull List<? extends T> messages)

Subclasses may override this method to alter the validation behavior in specific cases. Although the null
is accepted as return value to indicate that there are no constraint violations, implementations are encouraged
to return an empty Set instead.
