On the "Design for the task" and "design for the structure", has been repeatedly elaborated before, if you have no impression, you can first look at: "Design principles vs." and "for product structure design, for the user task design."
"Design, you should pay attention to let the task smooth, but also need to make the structure clear." ”
If you agree with this point, then the question is: what should I do?
Here's a design approach, a design approach that takes into account the information arc

A simple method to implement timed tasks under Web application
In Web mode, if we want to implement certain tasks on a regular basis, in addition to using quartz and other third-party open source tools, we can use timer and Timetask to complete the specified timing tasks:
The first step: Create a task management class, implement Servletcontextlistener
