Java，JavaScript和ABAP通过代码取得当前代码的调用栈Callstack

Java

 StackTraceElement stack[] = Thread.currentThread().getStackTrace();

System.out.println("Callstack test"); for(int i = 0; i < stack.length; i++){

       System.out.println("Jerry:" + stack[i].getClassName() + ":" + stack[i].getMethodName() + "-----");

} 

测试：

JavaScript

 function getCallStack() { var stack = "Callstack:", fn =arguments.callee; while ( (fn = fn.caller) ) {

         stack = stack + "\n" +fn.name;

   } return stack;

} function test1() { console.log(getCallStack());

} function test2() {

    test1();

} function test3() {

    test2();

} function test4() {

    test3();

}

test4(); 

测试：

ABAP

 CALL FUNCTION 'SYSTEM_CALLSTACK' IMPORTING

         callstack = lt_callstack.
