Method Detail

invokeUnderTrace

protected Object invokeUnderTrace(MethodInvocation invocation,
                                  Log logger)

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().

The passed-in Log instance will have log level "trace" enabled. Subclasses do not have to check for this again.

Specified by:

invokeUnderTrace in class AbstractTraceInterceptor

logger - the Log to write trace messages to

Returns:

the result of the call to MethodInvocation.proceed()

Throws:

Throwable - if the call to MethodInvocation.proceed() encountered any errors
