	private String name;
	private ArrayList<Column> columns;
	private ArrayList<String> keys;
}

获得

	public static void main(String[] args) throws NoSuchFieldException,
			SecurityException {
		Field f = Table.class.getDeclaredField("columns");
		Type genericType = f.getGenericType();
		if (genericType != null) {
			ParameterizedType pt = (ParameterizedType) genericType;
			Type type = pt.getActualTypeArguments()[0];
			System.out.println(type);
		}
	}
