• Checking result and running custom logic (implements ResultHandler)

Usage

using @NonRepeatable annotate in controller layer:

1. only once

   @NonRepeatable
   public String onlyOnce(String data) {
       return "Your submission is accepted.";
   }

2. don't repeat in one seconds interval.

   @NonRepeatable(interval = NonRepeatable.DEFAULT_INTERVAL)
   public String defaultInterval(String data) {
       return "Your submission is accepted.";
   }

3. custom interval

   @NonRepeatable(interval = 2000)
   public String customInterval(String data) {
       return "Your submission is accepted.";
   }

4. using specified request parameter

   parameter value will retrieve from HttpServletRequest#getParameterValues();

   @GetMapping("/hello")
   @NonRepeatable(strategy = IdentifierStrategy.REQUEST_PARAMETER, parameterName = "request_id")
   public String customInterval(String data) {
       return "Your submission is accepted.";
   }

5. using all parameters in request

   @GetMapping("/hi")
   @NonRepeatable(strategy = IdentifierStrategy.REQUEST_PARAMETER)
   public String customInterval(String data) {
       return "Your submission is accepted.";
   }
