java - How to get a value from an @Around declared method using AspectJ? -

this code snippet:

@around("execution(* de.my.package.path.controller.recommendationcontroller.recommenditems*(..))")     public object measuretimewithoverhead(proceedingjoinpoint joinpoint) throws throwable {         long startnanotime = system.nanotime();         object proceed = joinpoint.proceed();         long endnanotime = system.nanotime();         long diff = endnanotime - startnanotime;         system.out.println("elapsed time: " + (diff));         return proceed;     } 

i want use value of "diff" variable in further program. how can retrieve value? possible @ all?

(btw, working on spring 4.0.2 mvc application)

currently, no. diff variable local variable , therefore accessible within body of method, after it's been declared (and initialized).

aop advice meant add additional behavior (by executing code) @ point in execution of program. it's self contained component. can know code it's intercepting, not vice-versa.

there work arounds if need this, but don't recommend it. can use static threadlocal in class , set value whatever diff is. can access threadlocal anywhere else.
