invokeUnderTrace

protected Object invokeUnderTrace(MethodInvocation invocation,

                           throws Throwable

从类复制的说明: 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, and may delegate to writeToLog for actual messages to be written.

指定者:

invokeUnderTrace 在类中 AbstractTraceInterceptor

logger - the Log to write trace messages to

返回:

the result of the call to MethodInvocation.proceed()

抛出:

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