REST API前端请求和后端接收

1、get请求，带"?"
http://localhost:8080/api/aop/getResult?param=123

    @GetMapping("getResult")
    public ResponseEntity<String> getResult(@RequestParam("param") String param){

        return new ResponseEntity<>("12345678", HttpStatus.OK);
    }

2、get请求，不带"?"
http://localhost:8080/api/aop/getResult/123

    @GetMapping("getResult/{param}")
    @Loggable
    public ResponseEntity<String> getResult(@PathVariable("param") String param){

        return new ResponseEntity<>("12345678", HttpStatus.OK);
    }
