想根据id和parentid处理成下面这样的

[{

"main": {

"id": 7510,

"parentid": 0,

"createemployeecd": 1014,

"createemployeename": "张三",

"comment": "大体了解",

"createtime": "2018-11-13 16:37:46.387231"

},

"reply": [{

"id": 7511,

"parentid": 7510,

"createemployeecd": 1015,

"createemployeename": "李四",

"comment": "大体了解",

"createtime": "2018-11-13 16:37:46.387231"

}, {

"id": 7513,

"parentid": 7511,

"createemployeecd": 1017,

"createemployeename": "陈小六",

"comment": "大体了解",
