How Spring JDBC Auto configuration works internally ?🤔 Spring Boot Foundation tutorial | MySQL

Ever thought ? how spring boot connects to database ? How Spring JDBC Auto configuration works internally ? How Spring auto configures the jdbc template and datasource ? This is one of the import concept which will build your Spring Boot Foundation. In this tutorial, We will be learning this topic with a practical approach which will prepare us for the spring boot Interview as well. To execute any sql statements over a database , first we need a connection object. The Datasource component takes connection creation responsibility which is later used by JdbcTemplate under the hood to connect to any database like MySQL before executing any SQL queries. If the DataSource and JdbcTemplate object creation has not done by the Developer , Spring boot does it by using its autoconfiguraiton feature. The components like DataSourceAutoConfiguration and JdbcTemplateAutoConfiguration does this work under the hood. In this video we have used different classes to create connection object which will be used by the framework under the hood. We have used DriverManager Datasource , Hikari connection pool, C3p0 connection pool , DBCP connection pooling example as well. A connection pool helps in creating a number of connections during the server bootstrap itself which is used by the framework before invoking any sql queries over the database. This helps in performance optimisation. Using the connection pool, a same connection can be reused numbers of time and helps in reducing connection creation time for each db operation. Hikari is used as a default Connection Pool in spring boot. Let’s learn how spring boot configures all these internally through autoconfiguration, if not set by the developer.
