described detail

SetTimeout and setinterval do the countdown, then found that if the front closure, the countdown to failure, so the transfer to the background, but the individual on the countdown and in Java and front end and are less likely to be, thinking of the front-end began to make an appointment after back end, sends a signal to remind the back-end to start the countdown, then use half an hour a sign in to determine whether a user default and obtain a countdown from the backend, if default, seats are released, will be included in the default user, if sign in successfully, seat is not released,
Want to consult the related code, the events tasks and trigger should be how to operate. Predecessors to give directions!

CodePudding user response:

The countdown, let the front end to a countdown time, join in the cache, timing task calls to judge whether the default, corresponding to the cache, default set for booking seat seat, record the user defaults, there is no default normal booking successful process
