Class RemoteInvocationTraceInterceptor

java.lang.Object

org.springframework.remoting.support.RemoteInvocationTraceInterceptor

All Implemented Interfaces:

Advice, Interceptor, MethodInterceptor

public class RemoteInvocationTraceInterceptor
extends Object
implements 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).
