All Implemented Interfaces:: Serializable, Advice, Interceptor, MethodInterceptor

public class PerformanceMonitorInterceptor
extends AbstractMonitoringInterceptor
extends AbstractMonitoringInterceptor

Simple AOP Alliance MethodInterceptor for performance monitoring. This interceptor has no effect on the intercepted method call.

Uses a StopWatch for the actual performance measuring.

PerformanceMonitorInterceptor

public PerformanceMonitorInterceptor(boolean useDynamicLogger)

Method Detail

invokeUnderTrace

protected Object invokeUnderTrace(MethodInvocation invocation,
                                  Log logger)
                           throws Throwable

Description copied from class: AbstractTraceInterceptor

Subclasses must override this method to perform any tracing around the supplied MethodInvocation. Subclasses are responsible for ensuring that the MethodInvocation actually executes by calling MethodInvocation.proceed().

By default, the passed-in Log instance will have log level "trace" enabled. Subclasses do not have to check for this again, unless they overwrite the isInterceptorEnabled method to modify the default behavior.
