How to handle tasks not executing after restarting quartz?

If tasks are not executing after restarting Quartz, you can try the following troubleshooting steps:

1. Check Quartz configuration: Make sure that the scheduler and job store configuration settings in the Quartz configuration file are correctly configured, and that they are properly connected to the database or other storage.
2. Check the job trigger: Verify the configuration of the job trigger, including the trigger time, repeat rule, etc. It may be necessary to reconfigure the trigger and restart Quartz.
3. Check homework class: Confirm the code logic of the homework class is correct, including the implementation of the task execution method, parameter passing, etc. You can try manually calling the methods of the homework class to verify if it runs properly.
4. Check the status of the task: Ensure that the task is running smoothly, without any interruptions or errors. This can be done by using Quartz’s management tools or API to monitor and make changes if necessary.
5. Check the job scheduler: Ensure that the job scheduler is running normally, such as if it is running or paused. It can also be viewed and modified through the management tools or API provided by Quartz.

If the above solutions do not resolve the issue, you can try redeploying Quartz or checking the Quartz log files for more detailed error information to further pinpoint and resolve the issue.
