通过反射获取泛型参数类型

public class ReflectDemo2 {

Map<String,Integer> map = new HashMap<String, Integer>();

List<String> list = new ArrayList<String>();

/**
* @param args
* @throws NoSuchFieldException
* @throws SecurityException
*/
public static void main(String[] args) throws SecurityException, NoSuchFieldException {
// TODO Auto-generated method stub
Class clazz = ReflectDemo2.class;

Field f = clazz.getDeclaredField("list");

Class a = f.getType();

System.out.println(a.getName());

Type t = f.getGenericType();

ParameterizedType pt = (ParameterizedType)t;

Type[] ptas = pt.getActualTypeArguments();

for(Type pta : ptas){
System.out.println(pta);
}

}

}
