Return HTTP code 200 from Spring REST API

Question

I want to use this code to receive http link with values:

@PostMapping(value = "/v1/notification")
public String handleNotifications(@RequestParam("notification") String itemid) {
    // parse here the values
    return "result successful result";
}

How I can return http code 200 - successful response?

And also for example if there is a code exception into code processing how can I return error 404?

Answer 1

If you are using spring:

@PostMapping(value = "/v1/notification")
public ResponseEntity handleNotifications(@RequestParam("notification") String itemid) {
    // parse here the values
    return ResponseEntity.ok().build(); 
    //OR ResponseEntity.ok("body goes here");
}
