接口返回json的取值记录总结

我的测试接口返回是不同类型的json数据，判断时需要取值，这几次用的是这三个，做个记录

1、{“id":"1111","sex":"nv","age":"11","core":"100"}

Map<String,Object>userData=mapper.readValue(val,Map.Class);

userData.get("id")....或userData.get(0)......

2、json数组，用list[{“id":"1111","sex":"nv","age":"11","core":"100"}]

List<Map<String,Object>>userData=mapper.readValue(val,List.Class);

userData.get(0).get("id")....注：get(0)是第一个数据

3、[111,222,3333]

List<Object>userData=mapper.readValue(val,List.Class);

userData.get(0).....
