Recursive method Everyone should be very familiar with, in short, the method internally called itself, so that repeated repeated repetition of the execution,

But to worry about the cycle of death yo ...

When our system needs to dynamically generate menus, which means that our system's menus are in the database, the database structure is similar to the following:
