Sending % through @RequestParam in Spring

How to send % using @RequestParam in Spring ?

I'm calling the API by this URL : http://localhost:8080/springmvc/test?param1=%

But I'm not able to get the % in the API. When I'm debugging, I'm getting param1 = null but I want to get the real character %. How to get that ?

This is my API :

public List<Test> testParam(
            @PathVariable("test") string test,
            @RequestParam(value = "param1", required = false) string myParaml) {
  ...
}
Solution

  • You have to send special characters in UTF-8 encoded standard in the URL.

    Try to send % as %25, which is UTF-8 encoded equivalent.

    http://localhost:8080/springmvc/test?param1=%25

    This will work. Refer here for more.
