JAVA中JSONObject对象和Map对象之间的相互转换

如json字符串：{"contend":[{"bid":"22","carid":"0"},{"bid":"22","carid":"0"}],"result":100,"total":2}

下面直接附代码：

//json字符串
String jsondata="{"contend":[{"bid":"22","carid":"0"},{"bid":"22","carid":"0"}],"result":100,"total":2}";
JSonObject obj= JSON.parseObject(jsondata);
//map对象
Map data =new HashMap<>();
//循环转换
 Iterator it =obj.entrySet().iterator();
 while (it.hasNext()) {
  Map.Entry entry = (Entry) it.next();
  data.put(entry.getKey(), entry.getValue());
 }
System.out.println("map对象:"+data.toString());

下面是输出内容：

 {total=2, contend=[{"carid":"0","bid":"22"},{"carid":"0","bid":"22"}], result=100}

//map对象
Map data =new HashMap<>();
String x =JSONObject.toJSonString(data);
System.out.println("json字符串:"+x);

下面是输出内容：

{"total":2,"result":100,"contend":[{"carid":"0","bid":"22"},{"carid":"0","bid":"22"}]}
