python 反射调用 反射调用get方法

public Object setDate(ResultSet rs,Object o) throws ClassNotFoundException, InstantiationException, IllegalAccessException, IntrospectionException, IllegalArgumentException, InvocationTargetException, SQLException{
		Class cs = Class.forName(o.getClass().getName());
		Field [] fileds = cs.getDeclaredFields();
			for (Field field : fileds) {				PropertyDescriptor pd = new PropertyDescriptor(field.getName(),cs);
//获取所有set方法
				Method method = pd.getWriteMethod();
				//利用set方法赋值
				method.invoke(o,rs.getString(field.getName()));
			}
		return o;
