2.試験方法

	@PostMapping("/test")
    @ResponseBody
    public Map<String, Object> getMsg(String id, String name) {
    
    
        Map<String, Object> map = new HashMap<>();
        map.put("result", "response msg");
        map.put("id", id);
        map.put("name", name);
        return map;
    }
