Get values with Spring Boot from http link

Question

I want to get the values from this http link:

https://www.test.com/notification?con=41280440000097&dp=1232&type=single

https://www.test.com/notification?con=41280440000097&sec=1232

I tried to implement this Spring code:

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

But how I can parse the http link and get the values for example in ArrayList of HashMap?

your controller method should be like this with RequestParam to get the values from request, you can make RequestParam optional withrequired=falseand you can set default value also(@RequestParam(value = "i", defaultValue = "10") int i`

 @PostMapping(value = "/v1/notification")
public String handleNotifications(@RequestParam(value="con", required=false) String itemid, @RequestParam(value="dp", required=false) String dp, @RequestParam(value="type", required=false) String type ) 
    {
     // you can use all these values directly in this method
    // parse here the values
return "result";
}

What if required param is not found? Error will be thrown? – Peter Penzov Aug 06 '18 at 20:26
it will null, no error, if you don't want null set default value – Ryuzaki L Aug 06 '18 at 20:28
Can you extend the post please. Also is there any security that I can add? – Peter Penzov Aug 06 '18 at 20:31
can you please be more specific ? what do you mean by security ? – Ryuzaki L Aug 06 '18 at 20:34
For injecting very long string. – Peter Penzov Aug 06 '18 at 20:36
Are there any Spring filters? – Peter Penzov Aug 06 '18 at 20:36
it depends on requirement – Ryuzaki L Aug 06 '18 at 21:34
