In this video, we will learn to configure spring security with database (MySql). In the previous session we have coded an application with inmemeoryuserdetails manager and stored the registered users data inside the server memory. In this video, we will change the logic for user details saving and we will store the details of an user inside the database.

We have a ready made api available called “JdbcUserDetailsManager” in spring security which can help us to createUser , deleteUser, updateUser, loadUserByUsername. We don’t have to write the logic for the above methods , the api methods implementations are given by spring framework and are ready to use.

Since we will be using spring security’s own implemented methods to persist and manipulate data, we need to use spring security user schema and authorities schema. For an example to store a user, we need to create exactly a table named called Users and the columns names will be exactly username, password, enabled. We don’t have the luxury here to customise the table / column name.

Let’s explore how jdbcuserdetailsmanager works internally ?
