UserDetailsManager & JdbcUserDetailsManager | Database Authentication with MySQL + Docker | Video#11

Описание: 🚀 In this video, we take a deep dive into UserDetailsManager and JdbcUserDetailsManager in Spring Security and learn how to implement database-based authentication using MySQL instead of in-memory users.

We will start by setting up a MySQL database using Docker, then create the required users and authorities tables used by Spring Security. After that, we will insert sample users into the database and configure Spring Boot with JdbcUserDetailsManager to authenticate users directly from the database.

This approach is commonly used in real-world production applications, where user credentials and roles are stored securely in a database.

If you are learning Spring Security, backend authentication, or preparing for Java backend interviews, this video will help you clearly understand how database authentication works in Spring Boot.
