Application Scenario 1: Set the primary and foreign key constraints in the database and set the delete cascade of the database. In hibernate, set inverse = true, cascade = all-delete-orphan For example: Set insert = "false" update = "false" on allow-to-one" For example: This enables cascading deletion. This method can have foreign key constraints. In addition, it is convenient to discard hibernate, and the coupling with hibernate is not very clo

The general idea is this: in order not to let the previous page refresh, I used an IFRAME to sneak into a two-level sub-page, to read the data in the database, and finally pass the desired data to the parent page, complete the selection and transfer of data. The main program code is as follows (some code changes, but does not affect functionality): Parent page reg.html: Sub-page city.php: Please select your province include_once ("db.php"), $sql = "SELECT * from Province order by sh_i
