public class LoggingInterceptor<T extends Message<?>> extends Object implements MessageDispatchInterceptor<T>, MessageHandlerInterceptor<T>
MessageDispatchInterceptor and MessageHandlerInterceptor implementation that logs dispatched and
incoming messages, and their result, to a SLF4J logger. Allows configuration of the name under which the logger
should log the statements.
Dispatched, incoming messages and successful executions are logged at the INFO level. Processing errors are
logged using the WARN level.| 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 messageCopyright © 2010–2020.
