通过map转换成json

代码如下：

     public static void main(String[] args) {
     setMapToJSON();
      }
    public static void setMapToJSON() {

    HashMap<String, Object> root = new HashMap<String, Object>(); 
    root.put("errorCode", 0);
    root.put("errorMsg", "调用接口成功");

    List<Map<String, String>> dataArr = new ArrayList<Map<String, String>>();
    
    Map<String, String> userhelei = new HashMap<String, String>();
    userhelei.put("userName", "贺雷");
    userhelei.put("position", "技术网站负责人");
    userhelei.put("webAddres", "www.ithelei.com");
    
    Map<String, String> ithelei = new HashMap<String, String>();
    ithelei.put("userName", "老大");
    ithelei.put("position", "信融集团");
    ithelei.put("webAddres", "www.wayboo.com");
    
    dataArr.add(ithelei);
    dataArr.add(userhelei);
    root.put("data", dataArr);
    System.out.println(new JSONObject().toJSONString(root));
}
