REAL-TIME: Spring Bean life cycle using @PostConstruct |@PreDestroy |init - method| destroy -method

[@SeleniumExpress]

FYI People who are using Java 9+ both @PostConstruct and @PreDestroy annotations are part of Java EE. And since Java EE has been deprecated in Java 9 and removed in Java 11 we have to add an additional dependency to use these annotations: if you are using maven javax.annotation javax.annotation-api 1.3.2 If you adding the jar manually, click on the below link mvnrepository.com/artifact/javax.annotation/javax.annotation-api/1.3.2 inside files column, you will see pom and jar click on the jar and your jar will be downloaded. add it to the classpath as an external jar by configuring the build

Hi...did u add any video on bean scopes?...u said in this video its an important concept for interviews as well but i am unable to find any video on it..

[@gollaveerakumar2434]

bro getting an error while wsing postConstructor

[@SeleniumExpress]

Guys, I could have easily complete this concept within 30 mints including all three approaches. but I didn't want any beginners to miss a real time scenario and that's why it's extended more than an hour. Take breaks while watching it and let me know whether the time you spent with this video really worth it . Just want some honest review and don't hesitate to raise a red flag ⛳ Thanks, Abhilash 🙂

I learned spring core during my CDAC (1 yr ago) but it seems like I stating forgetting the things so to brush up, I watched your whole series of spring core tutorial. Now I'm energized with lot of confidence in spring core... Also going to watch your spring mvc and spring boot series. Thank you so much abhilash for making tutorial for us. Your explanation is very simple everyone can understand it. God bless you 😇❣️

[@amithghosh3332]

I am not exaggerating.... but u r a savior of lakhs of java developers who are stuck with training programs and coaching centers. 1 hour into your channel and the next thing I know is I am the master of that concept in addition to the confidence and self esteem. I got hopes that I can code too.......

[@shekarprem]

Super bro. one of best content in this domain. I got good confidence now.

[@aniketshukla9568]

From first video till here...didn't miss even a single minute. I didn't know even 'S' of spring but now all I can say is that I am not afraid of learning more about spring. Thanks Abhilash.

[@UmarFarooq-un6jm]

20:38 When a database connection is opened, it occupies system resources such as memory and file descriptors, and if you don't close it, those resources will not be freed up until the connection is terminated, which can lead to resource depletion and system instability. Closing the connection is also important because it ensures that any uncommitted transactions are rolled back or committed to the database. If you do not close the connection properly, the transaction may be left in an uncommitted state, which can cause data inconsistencies and other issues.

[@alfloriesz5703]

These series of videos have been really helpful so far, thanks for the great content.

[@shreyakhatal9952]

Awesome tutorial!! Watched this 1 year back and tagain thi year to brush up my concepts. Thank you so much!!

Lots of people have knowledge and it is also true so many people are intelligent. BUT HAVING KNOWLEDGE AND BEING AN INTELLIGENT PERSON IT DOESN'T MEAN ANYONE CAN BECOME A GOOD TEACHER. **** Teaching is an art and YOU are the best teacher *****

[@PriyaSingh-px3nu]

The database is a resource if you don't close the connection other program or another tread will not be able to use it so that's why it is recommended to close the connection..........I am very thankful to you that you are sharing your knowledge with us, your teaching style is phenomenal. God bless you

[@learnjava100]

We close a DB connection so we can release any DB resource such as cursors that the connection might be holding on to. Also when you get a connection from a pool using datasource which is what we do in production environment, then the connection can be returned back to the pool for reuse.

[@sailynagarkar1199]

[@ankitshukla8972]

It is important to close a JDBC Connection once you are done with it. A database connection takes up an amount of resources, both inside your own application, but especially on the database server.

[@umeshdevalia5970]

[@ramgurnani9723]

If you open the connection and don't close after the execution of the program then it will remain open forever and connection pool is going to increase in your server and because of that server crashes and needs to restart the server.

[@suhaasmohandos5869]

The videos are really good. Where is the explaination for beanpostprocessor?

[@vamsidharreddy2628]

[@MINIRAJ212]

Hey abhilash ... Thank you so much for this amazing series of tutorial ... It helped me a lot ... Once again thank you so much ... 😊😊😊👌👌👍👍👍

[@munaswamy6595]

With out close the connection the connection pool size will limited that's why u must've close the connection

[@earntotrade6030]

If any client uses DB connection and didn’t close it then it assumed to be still-in-use and thereby other clients waiting for their turn. Now, at one point no DB connection available to server further clients. Resources are costly so optimal use for same is important.

[@SpringLearner443]

thanks alot!!

[@prithvirajh5363]

Hi, Abhilash I'm watching your Spring videos. It's really good and understandable videos. Thanks for making the videos, And please make a video on "Spring MVC", "Spring BOOT" and "Hibernate all topics". I request you to make it.
