PerformanceMonitorInterceptor
public PerformanceMonitorInterceptor()
Create a new PerformanceMonitorInterceptor with a static logger.
PerformanceMonitorInterceptor
public PerformanceMonitorInterceptor(boolean useDynamicLogger)
Create a new PerformanceMonitorInterceptor with a dynamic or static logger, according to the given flag.- Parameters:
useDynamicLogger- whether to use a dynamic logger or a static logger- See Also:

Method Detail
invokeUnderTrace
protected Object invokeUnderTrace(MethodInvocation invocation, Log logger) throws Throwable
Description copied from class:AbstractTraceInterceptorSubclasses must override this method to perform any tracing around the suppliedMethodInvocation. Subclasses are responsible for ensuring that theMethodInvocationactually executes by callingMethodInvocation.proceed().By default, the passed-in
Loginstance will have log level "trace" enabled. Subclasses do not have to check for this again, unless they overwrite theisInterceptorEnabledmethod to modify the default behavior, and may delegate towriteToLogfor actual messages to be written.- Specified by:
invokeUnderTracein classAbstractTraceInterceptorlogger- theLogto write trace messages to- Returns:
- the result of the call to
MethodInvocation.proceed() - Throws:
Throwable- if the call toMethodInvocation.proceed()encountered any errors- See Also:
