Top 22 Spring Boot Questions for Java Interviews

Spring Boot Interview Questions with Answers for Java developers

Hello folks, there is no doubt that the Spring Boot is now the standard way to develop Java application using Spring Framework, and that's why Spring Boot Questions are increasingly becoming popular on Java interviews.

In the past, I have shared Java Multithreading questions, Java Serialization questions, System Design interview questions and Enum Interview Questions and  @RestController vs. @Controller, but I haven't got a chance to share any questions on Spring Boot, Spring Cloud, and Microservices.

After a couple of personal requests from my readers, I thought to write about, and here comes my list of top 22 Spring Boot interview questions for Java developers.

In this list, you will tackle all-important Spring Boot concepts from an interview point of view like auto-configuration, starter dependencies, Spring Boot CLI, and Actuator.

Once you have gone through this list, you should have sufficient knowledge to tackle any Spring Boot question on the real interviews.

Arguably, Spring Boot is the most significant and exciting thing that happens in Java development for a long time, I guess, after the release of Java 5 and Java 8.

The main advantage of using Spring Boot is that it greatly simplifies the use of the Spring framework for Java development.

It addresses most of the concerns a new developer or a team has about using a framework like configurations, dependencies, setup hurdles, etc.

It's the kind of application development framework Java programmers have been looking for a long time, and that's why it's very important from Java and Spring point of view.

Btw, If you are preparing for Spring interview you can take a look at them and if you still need more questions you can also take help from books like Grokking the Spring Boot Interview and this 200+ Spring interview questions course on Udemy which is probably the biggest list of Spring interview questions I have come across. They are very affordable, you can get them for just $9.9

Also, here is a nice Spring Boot Cheat sheet to revise key concepts before interviews
