public class: RemoteInvocationTraceInterceptor [javadoc | source]

java.lang.Object
   org.springframework.remoting.support.RemoteInvocationTraceInterceptor

All Implemented Interfaces:
org.aopalliance.intercept.MethodInterceptor

AOP Alliance MethodInterceptor for tracing remote invocations. Automatically applied by RemoteExporter and its subclasses.

Logs an incoming remote call as well as the finished processing of a remote call at DEBUG level. If the processing of a remote call results in a checked exception, the exception will get logged at INFO level; if it results in an unchecked exception (or error), the exception will get logged at WARN level.

The logging of exceptions is particularly useful to save the stacktrace information on the server-side rather than just propagating the exception to the client (who might or might not log it properly).
