JAVA对象转json

Object o = JSON.toJSON(student);
System.out.println(o.toString());
System.out.println("=====");
String s = JSON.toJSONString(student);
System.out.println(s);

JSON转对象、转Map

JSONObject object = JSONObject.parseObject("{\"boolean\":true,\"string\":\"string\",\"list\":[1,2,3],\"int\":2}");Map map1 = JSONObject.parseObject("{\"boolean\":true,\"string\":\"string\",\"list\":[1,2,3],\"int\":2}",Map.class);
