#Around advice returning correct response but at client side response is null or undefined - spring

Question

I am trying to apply Around advice to my "Login.jsp" with angular js. And the problem is my controller method is check and I am applying around advice to check method but when I run my application I will get undefined as response at Login.jsp. And but the result which I had printed in my advice contains expected result.But I am not getting it on client side.
AroundAdvice.java
#Aspect #Component
public class AroundAdvice {
static Logger log = Logger.getLogger(AfterLoginAspect.class.getName());
#Around("execution(* com.admin.controller.LoginController.check(..))")
public void logWrittter(ProceedingJoinPoint jp) throws Throwable {
SimpleDateFormat date=new SimpleDateFormat();
log.info("Date Time :: " + date.format(new Date().getTime()));
Object result = jp.proceed();
System.out.println("result around");
log.info("result :: " + result);
// returns {"get Status":"home"}
}
}
LoginController.jsp
// authentication check
#RequestMapping(value = "/PostFormData", method = RequestMethod.POST)
public #ResponseBody JSONObject check(#RequestBody LoginBo login) {
System.out.println("checkCredentials::" + login.getUserName());
String username = login.getUserName();
// log.info("uswername ::"+username);
JSONObject result = new JSONObject();
String encrptedpassword = encryptdPwd.encrypt(login.getPassWord());
boolean login_status = loginService.checkCredentials(username, encrptedpassword);
// log.info("login_status ::"+login_status);
// System.out.println("staus ::"+login_status);
if (login_status == true && login.isIs_system_generated_pwd() == true) {
System.out.println("sys gen chnge pwd:: " + login.isIs_system_generated_pwd());
result.put("getStatus", "change");
// System.out.println(resultPage);
// login.setIs_system_generated_pwd(false);
} else if (login_status == true && login.isIs_system_generated_pwd() == false) {
result.put("getStatus", "home");
// System.out.println("Home paege ");
} else {
result.put("getStatus", "error");
}
System.out.println("result ::" + result);
// log.info("result ::"+resultPage);
return result;
}

Your pointcut does not match because the advice has a void return type, but your method returns a JSONObject. So maybe you want to change your advice declaration to:
#Aspect #Component
public class AroundAdvice {
static Logger log = Logger.getLogger(AfterLoginAspect.class.getName());
#Around("execution(* com.admin.controller.LoginController.check(..))")
public JSONObject logWriter(ProceedingJoinPoint jp) throws Throwable {
SimpleDateFormat date=new SimpleDateFormat();
log.info("Date Time :: " + date.format(new Date().getTime()));
JSONObject result = (JSONObject) jp.proceed();
System.out.println("result around");
log.info("result :: " + result);
return result;
}
}
Please note
public JSONObject logWriter instead of public void logWrittter,
JSONObject result = (JSONObject) jp.proceed(); instead of Object result = jp.proceed(); and
return result; instead of no return value.
