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 messagepublic BiFunction<Integer,T,T> handle(List<T> messages)

message using the given validator. The default implementation
merely calls validator.validate(message).
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.message - The message to validatevalidator - The validator provided by the validator factorynull.Copyright © 2010–2017. All rights reserved.
