- 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.

JDBC Auto configuration- I have been haunted by this magic- Thanks for pulling the blanket away!
I hope to see videos on Spring Data JDBC and the difference with Spring Data JPA :)
Super Explanation
Thank you so much for the exceptional knowledge you have....we are so grateful to you 🙏🙏
Truly amazing and in-depth explanations, thanks a ton!!
Great
Very helpful 👏🏽
thanks a lot
Hi Bro,Expecting from you latest concepts.plz do waiting for that
Nice 👍👍 video
Thanks bro… can you create similar content on Distributed log tracing ?
Please create series on hibernate and core JDBC, servelts too. Thanks ❤
Thanks abhi❤
❤️
Hey Abhi, Thank you 😂
When will you start core Java ,jdbc servlet jsp classes
Abhliash do you have any kubernetes course
Incase thread pool, when thread complete it work, then it will go to dead state, then how it will go back to thread pool. What they have implemented under the hood.
Hi awesome even I had the same question ^_^
A Thread Pool is an alternative to creating a new thread per task to execute. Instead, a number of pre-created threads exist in a pool - into which you can submit tasks to be executed by these pooled threads. New tasks submitted to the pool are first stored internally in a queue. From this queue the pooled threads will take the tasks and execute them. Each thread in the thread pool executes in a loop that takes a new task from the internal task queue in the thread pool (or block if no tasks are available), executes the task, and then tries to take another task etc. repeatedly.
If you want to know more about the internals, then you can read more about concurrency in multithreading and Executor framework.
@@rakeshpal8730 Hi Rakesh thanks for the brief but honestly we know all this, our question is different.
Each thread dies after executing the "run" method then how has Threadpool done the implementation internally such that threads don't die but are rather re-used
i am in the exact doubt found this video
Sir when are you going to begin live courses
Just resumed the Live sessions from this week. You can raise an enquiry for the follow up. Incase you are a paid user, check your respective groups for updates.
Sir I wanna join new batches
When can be they get started
