fastjson类型转换

经常会用到JSONObject与实体类各种转换，今天记录一下
需要用到com.alibaba.fastjson.JSONObject

java，接到JSONObject转为实体

Member member = JSONObject.toJavaObject(request.getJSONObject("memberJSON"),Member.class);

kotlin，接到JSONObject转为实体

var  member =JSONObject.toJavaObject(request.getJSONObject("memberJSON"),Member ::class.java)

java，Object转换为JSONObject

 JSONObject memberJSON = (JSONObject) JSONObject.toJSON(memberObject);

kotlin，Object转换为JSONObject

val memberJSON = JSONObject.toJSON(memberObject) as JSONObject

kotlin，实体转为字符串

var jsonStr = JSONObject.toJSONString(member)

kotlin,JSON字符串转为JSONObject

var memberJSON = JSONObject.parseObject(jsonStr)

1.fastjson List转JSONArray

JSONArray array= JSONArray.parseArray(JSON.toJSONString(list))；

2.fastjson JSONArray转List

List<EventColAttr> list = JSONObject.parseArray(array.toJSONString(), EventColAttr.class);

3.fastjson 字符串转List

List<T> list = JSONObject.parseArray(str,T.class);
