timestamp插入数据库报空指针异常

[wudiawudi_2]

public void addOrder(Order order){
		try{
			String sql = "insert into orders(order_date,order_state,order_total,order_address,order_user_id,order_number,order_tel) values (?,?,?,?,?,?,?);";
			Timestamp timestamp = new Timestamp(order.getOrder_date().getTime());
			Object[] params = {timestamp,order.getOrder_state(),order.getOrder_total(),order.getOwner().getUser_address(),order.getOwner().getUser_id(),order.getOrder_number(),order.getOwner().getUser_tel()};
			qr.update(sql, params);
		}
		catch(SQLException e){
			throw new RuntimeException(e);
			
		}
	}

timestamp能获取到正确的值，但是会报如下异常，程序之前都能成功执行，突然报出这个异常
