springMVC接收get请求传递多个参数

@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("参数："+state+"/"+limberId+"/"+account);
        Map<String, Object> map = new HashMap<String, Object>();

        return map;
    }

多个参数时，需在每个变量前加@PathVariable注解，否则传到方法内的参数为空；

变量名称和位置一一对应。
