fastjson为何使用TypeReference？（下）

class java.util.HashMap
class java.lang.String
class java.lang.Integer
=====newclass=====
class java.util.AbstractMap
K
V
=====subclass=====
class java.util.HashMap
class java.lang.String
class java.lang.Integer

public class FieldGenericKest {
    public  Map<String,Integer> map = new HashMap<>();
    public List<Long> list = new ArrayList<>();
    public static void main(String[] args) throws Exception {
        FieldGenericKest kest = new FieldGenericKest();
        Field map = kest.getClass().getField("map");
        Field list = kest.getClass().getField("list");
        System.out.println("=====map=====");
        System.out.println("map.getType=" + map.getType());
        System.out.println("map.getGenericType=" + map.getGenericType());
        System.out.println("=====list=====");
        System.out.println("list.getType=" + list.getType());
        System.out.println("list.getGenericType=" + list.getGenericType());
    }
}

=====map=====
map.getType=interface java.util.Map
map.getGenericType=java.util.Map<java.lang.String, java.lang.Integer>
=====list=====
list.getType=interface java.util.List
list.getGenericType=java.util.List<java.lang.Long>

Object mapVal = map.get(kest);
if(mapVal != null){
    Class<?> clz = mapVal.getClass();
    System.out.println(mapVal.getClass().getName());
}
