Method Detail

invokeUnderTrace

protected java.lang.Object invokeUnderTrace(org.aopalliance.intercept.MethodInvocation invocation,
                                            org.apache.commons.logging.Log logger)
                                     throws java.lang.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.

Specified by:
invokeUnderTrace in class AbstractTraceInterceptor
logger - the Log to write trace messages to
Returns:
the result of the call to MethodInvocation.proceed()
Throws:
java.lang.Throwable - if the call to MethodInvocation.proceed() encountered any errors
