Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". Spring Boot helps you accelerate application development.
It looks at your classpath and at the beans you have configured, makes reasonable assumptions about what you are missing, and adds those items. With Spring Boot, you can focus more on business features and less on infrastructure.
For all Spring applications, you should start with the Spring Initializr. The Initializr offers a fast way to pull in all the dependencies you need for an application and does a lot of the setup for you.
Spring Boot Interview questions are usually tricky ones and we need to practice them before appearing for spring boot interviews.
A very common question asked is what is @SpringBootAnnotation
@SpringBootApplication is a convenience annotation that adds all of the following:
@Configuration: Tags the class as a source of bean definitions for the application context.
@EnableAutoConfiguration: Tells Spring Boot to start adding beans based on classpath settings, other beans, and various property settings. For example, if spring-web MVC is on the classpath, this annotation flags the application as a web application and activates key behaviors, such as setting up a DispatcherServlet.
@ComponentScan: Tells Spring to look for other components, configurations, and services in the com/example package, letting it find the controllers.

You are a hope, a confidence booster. Thank you for all of your hard work that you put for making these videos. Really grateful!
Thanks a ton Simran 🙂👍
Amazingly explained. Even a person who has never heard of springboot he/she will be able to crack an interview
Thanks 👍
But what is the use if that person will get the project so without knowing the concept, no one can survive...
Video is great 👍
Mam want this application code please send GitHub link

Been there 😃 I understand 👍
You are a "Java champion"
Not just java but all the java related technologies like spring hibernate etc
You are really doing a great job.
Requesting you Pl. Uploade other java related technologies interview questions and answers that you think you have missed and they are important
Special Thanks once again for this interview questions and answers series
🙏👍
Thanks Gokul 🙂. We are still in learning phase🙂🙂. You guys help us in understanding priorities n our day to day job in IT world helps us to cater these knowledge🙂🙂. Thanks for the nice world Gokul. It means a lot 🙏🙏
@@CodeDecode I have one suggestion ,
It would be really good if all the interview question which are mostly asked in real MNC interviews are subject wise compiled together
and answers for all those interview questions (short,simple and easy to understand not to lengthy with graphics diagrams where ever required for e.g. you have explained how the garbage collection happens or done by JVM) and also with program/code snippet where ever required and if you organised it in well structured manner and create a "Book" author by you and give some nice title
Say for e.g. "Career with Java"
And bring in to market belive me it would be of great successfull book
It should contain only java and related technologies which are like must for a "Java full stack developer"
Let's devide the java and technologies in to 3 tiers
1) UI or Front end/ presentation tier
2) Middle tier/ Business logic tier
3) Back end or database tier
Some of the technologies which
I know required for a full stack developer are as follows
1) UI or Front end/ presentation tier
HTML,CSS,JSP,JavaScript, JQuery, Ajax.
2) Middle tier/ Business logic tier
Core-java (up to java 15/16),
Advance java JDBC etc
servlet-JSP,
Struts framework
Struts1.3/Struts 2.x
Spring framework CORE,MVC,AOP,ORM,Annotatios,
JDBCTemplate,Spring-Hibernate integration,Spring Boot, Spring Cloud
3) Back end or database tier
Hibernate interview questions
RDBMS, SQL and PL-SQL
Web services
REST-Web Services
SOAP Web Services
Design Patterns 7-8 most commonly used
Some VCS interview questions and answers
SVN and GIT etc
"Career with Java"
(mostly asked in real MNC interviews) like for e.g. top 10 or top 20 questions including advance topics with program/code snippet
The book should be precisely composed like if around 20 technologies I have mentioned
If top 10 QAs covered the
Total 200 QAs
If top 20 QAs are covered then
Total 400 question answers
Some of the technologies may not required 20QA Like SVN GIT
And some may required more than 20QAs like CORE JAVA and spring framework.
Total book size should be within 100 to 150 pages
And price also should not be very high say for e.g for 100 pages book rs 100 and if pages are more then should increase the price accordingly
Let's say
For 150 Pages book
Price is Rs150
And if 1million copies are sold
10,00,000X150
15,00,00,000 will be total sale and
Publisher can give handsome return out of it around 20℅ I think minimum
It's just a suggestion but can be doable think about it.
it was very helpful thank youuuu :D
Thanks Hocine
I have watched whole series for spring boot and got selected

Amazing !🔥

Great job, very well explained 👌
Thanks
simply awesome
Thanks Abhiranjan 🙂🙂👍👍
Thank you so much for this video. I have a question on last video like how system will know that we write spring.active.profies=prod then it will take from the -prod file name what if I give the property file name as "prodd" or something else
System reads your application.properties file. While reading when it finds that you have overriden spring.active.profiles property , then it will know that you have different configurations for different environments. And what ever parameters you pass as a value to this property say xyz, it will then search for application-xyz.property file in your class path. If it finds that, it will load all required properties from there. If no such file or present in your path then it will give you error.
Its help full for me , Thanks for your effort
Thanks for writing back to us. 🙏👍
its very helpful , and nicely explain each topic which are very important for interview perspective
Thanks..
Thanks Yogesh. Sure we will create more such videos👍👍
Thanks, So much helpful video. Could you please provide that PPT's ?
