JSON 的幾種簡單格式和轉換

1、JSON對象---JSONObject
｛"fbaCode":"PHX4","fromProvince":"310000","fromCity":"310100","fromProvince":"310000"｝
2、JSON數組---JSONArray
[｛"fbaCode":"PHX4","fromProvince":"310000","fromCity":"310100","fromProvince":"310000"｝,｛"fbaCode2":"PHX4","fromProvince2":"310000","fromCity2":"310100","fromProvince2":"310000"｝]
3、JSON字符串
'{"name":"張三","sex":"男"}'
4、混合

=轉換=========
1、string ->json
String json
JSONObject jsonObject = new JSONObject(json)
2、字符串數組轉相對應的集合實體類 包：com.alibaba.fastjson
List models = JSONArray.parseArray(array, FbaRegionListModel.class);
3、實體類轉json字符串
String s = com.alibaba.fastjson.JSON.toJSONString(model)
4、集合轉JsonArray 數組
List models = JSONArray.parseArray(array, FbaRegionListModel.class)
JSONArray.toJSON(models)
