如果您只需要在一个地方进行这种行为，您可以使用标准 Java URLEncoder 位于控制器主体内部:

If you need this behavior only in a single place, you can encode the parameter back to the original form using the standard Java URLEncoder inside of the controller body:

@RequestMapping("/test")
public ResponseEntity<String> test(@RequestParam final String test) {
  String encodedParam = URLEncoder.encode(test, "UTF-8");
  return ResponseEntity.ok("Requested: " + encodedParam);
}
