springMVC接收get請求傳遞多個參數

@RequestMapping(value = "/sendSignal/{state}/{limberId}/{account}", method = RequestMethod.GET)
    @ResponseBody
    public Map<String, Object> signal(@PathVariable int state, @PathVariable String limberId, @PathVariable String account) {
        System.out.println("參數："+state+"/"+limberId+"/"+account);
        Map<String, Object> map = new HashMap<String, Object>();
       
        return map;
    }

多個參數時，需在每個變量前加@PathVariable注解，否則傳到方法內的參數為空；

變量名稱和位置一一對應。
