Backup MySQL Databases from Java, Spring Boot

Keeping backup of Database is really important for every system.

Please read this (5 Reasons why you need database backup) article about why we need database backup.

Here, I would like to make database backup everyday from Java, Spring Boot application.

Create controller class and import the following setting for scheduling.

Then, create new method with @Scheduled annotation inside the class.

Here, I use cron = "0 30 1 * * ?" so this cron task will run at 1:30 AM every day, every month.

And I use mysqldump command same as we are using with command prompt.

Use --databases option in mysqldump command for multiple databases

Use --all-databases option for all databases

Full code here and it will backup selected databases and keep sql file under "C:\home" folder. Enjoy!

Oh I forgot to mention about 2 parameters "dbUserName" and "dbUserPassword" which I didn't declare in the source code.

These parameters are the username and password of your database.
