Object转Map和Map转Object java

//Object转Map  Stunent是实体

Map map = JSONObject.parseObject(JSONObject.toJSONString(Stunent), Map.class);

Map<String,Object> map = JSONObject.parseObject(JSON.toJSONString(Stunent));

先通过JSONObject.toJSONString将实体转换成json字符串，再通过JSONObject.parseObject转为map

//Map转Object

Stunent stunent= JSON.parseObject(JSON.toJSONString(map), Stunent.class);

Stunent stunent2 = JSONObject.toJavaObject(JSON.toJSONString(map), Stunent.class);
