Implements abstract org.springframework.aop.interceptor.AbstractTraceInterceptor.invokeUnderTrace.

Doc from org.springframework.aop.interceptor.AbstractTraceInterceptor.invokeUnderTrace.

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, and may delegate to writeToLog for actual messages to be written.

Parameters
logger:Log

the Log to write trace messages to

Returns:Object

the result of the call to MethodInvocation.proceed()

Annotations
@Override
Exceptions
Throwable:
if the call to MethodInvocation.proceed() encountered any errors
