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);
		}
		

	}
