json - JAVA Reflection - JoinPoint -

i'm trying use java reflection details execution , save in gray log.

gray log methods accept join point parameters, can't information, i'd information cast json, can how ?

this i've tried:

methodsignature signature = (methodsignature) joinpoint.getsignature(); object[] args = joinpoint.getargs(); (object : args) {             if (a.getclass().tostring().tolowercase().contains("request")) {                 method[] methods = a.getclass().getmethods();                 (method m : methods){                     if (m.getname().substring(0, 3).tolowercase().equals("get")) {                         object result = m.invoke(a);                         jarray = new jsonarray();                         jobject = new jsonobject();                         if (result instanceof list<?>) { ... } } } } } 

this implies have test instanceof same result, want info , parse json.
