Children in to write a small program WeChat! In spring the boot writing background,
Want to finish such a function: seat reservation, a back-end transmission data, the back-end in change the database related fields, the seat of the state (without reservation) from 0 to 1 (booking), and add a regular tasks or redis or dead-letter queue to monitor what is good, judge whether the user of the 30 seconds after booking the seat sign in, if you sign in, do not change, if no sign in, then the seat reservation status of the database will be 1 to 0,

This feature is similar to the timeout did not pay the processing of orders, or overtime attendance task did not sign in processing!
