Java Order Auto-Cancellation Guide

To implement the function of automatically canceling orders that have timed out, follow these steps:

1. Add a field in the order table to record the time when the order was created.
2. Set up a scheduled task in the system to periodically check if any orders in the order table have exceeded the payment deadline.
3. When the difference between the time the order was created and the current time exceeds the set timeout period, the order status will be changed to canceled.
4. One way to achieve this is by creating a scheduled task that runs at regular intervals to check if any orders in the order table have remained unpaid past the deadline.
5. If the order is not paid within the time limit, the order status will be updated to canceled. The corresponding method can be called in a scheduled task to cancel the order.

By following the above steps, the function of automatically canceling orders that have timed out can be achieved. This can improve the efficiency of the system, save labor costs, and enhance user experience at the same time.
