Congratulations,you have made all the configurations required for the Paypal payment.

Now lets come to JAVA part to handle success/failure from paypal.

Create a method in controller to handle paypal redirection URL like below(you will get mulitple request parameters like "st","amt","cc","tx" status,amount,currency,transaction id etc.).

@RequestMapping(value="/paypal/success")  //this url should map which you configured in step 5
    public String success(ModelMap modelMap,HttpServletRequest httpServletRequest,Model uiModel) throws Exception{
        Enumeration<String> parameterNames = httpServletRequest.getParameterNames();

        while (parameterNames.hasMoreElements()) {

            String paramName = parameterNames.nextElement();
            System.out.println("paramName : "+paramName);
            String[] paramValues = httpServletRequest.getParameterValues(paramName);

            for (int i = 0; i < paramValues.length; i++) {
                String paramValue = paramValues[i];
                System.out.println("paramName : " + paramName+ ",paramValue : " + paramValue);
                //your logic goes here

            }
        }

    }
