I am trying to implement spring AOP @Before . Here is the method

 @Before("execution(* com.dummy.pkg..*.*(..))")
    public Response<Object> beforeServiceAspect(JoinPoint joinPoint) throws Exception {

            Object[] signatureArgs = joinPoint.getArgs();

           String sessionId=(String) signatureArgs[0];


         if(null==sessionId||sessionId.isEmpty()||!loginService.getUserInfo(sessionId))
           {
                Response.setStatusCode("401");
                Response.setC
                Response.setResultString("Unauthorized User");
                  return  Response;    
 //this is where i  want to  return in case of program enter here   
//**point 1** 
           }
   //**point 2**  where execution reaches then resume normal flow 
return "";
}

Here is two thing i wanat to achieve

1. If flow reaches to point 1 then it return from that point itself.It should not go further and call should return back.
2. If flow reaches to point 2 , it resume normal flow and call internal method. what happening now is in both cases it flowing normal flow and keep calling internal methods.
