用SpringMVC的responseBody的標籤來將資料轉成json格式，然後給app使用

程式碼如下：

@RequestMapping(value = "/jsontest")
    @ResponseBody
    public Map<String, User> getjsopn() {
        User user=new User(1,"xuweijei","xuwiejei","xwj","nan","22","zhuhai");
        String[] arrays=new String[]{"a","b","c"};
        user.setArrays(arrays);
        Map<String,User>map=new HashMap<String, User>();
        map.put("user",user);
        return map;
    }
 

SpringMVC還有其他方法可以實現，待日後再完善補充這篇部落格
