Objective
I wrote this application to explain the mechanism of different components of the Spring framework.

- Multi language UI
Main component used
- Project Reactor 3.7.X

- Spring Security 6.4.X
- Spring R2DBC 6.2.X

Database
By default, data is stored in an embedded H2 database. Schema and data is imported when the application starts and all data will be lost after application shutdown.
MySQL database is also supported. In order to switch to MySQL database, first to modify the following properties located in application.properties file.
spring.r2dbc.url=r2dbc:mysql://localhost:3306/database-name
spring.r2dbc.username=root
spring.r2dbc.password=password
Then deactivate 'db-h2' and activate 'db-mysql' Maven profiles when starting the application. And activate 'init-db' profiles also when starting the application at the first time.
