Hello Java programmers, If you are preparing for Java and Spring Interview but wondering which topics and concepts to prepare then you have come to the right place.

In the past, I have shared top Spring MVC interview questions as well best courses to learn Spring and Spring Boot for both beginners and experienced Java developers and in this article, I am going to share 13 essential Spring topics you should prepare for your next Spring Boot interview and resources.

Spring Framework is the most popular and almost a standard framework for developing Java applications, both core java as well as Java web application which runs on servers like Tomcat.

Let’s be honest, cracking a spring Boot interview is not easy because Spring is very vast and hard to master but you can turn the clock in your favor by adopting a strategy to prepare for essential topics and concepts

Like Java, Spring Framework is also very vast and there are several sub-projects like Containers, Core Spring Concepts like IoC and Dependency Injection, Spring MVC, Spring Boot, Spring Data JPA, Spring Cloud, Spring Boot Testing, Spring Security, Spring Boot Actuator, Spring Boot Auto Configuration, Spring AOP, and miscellaneous Spring APIs.

Here is a list of essential Spring FRamework topics you should prepare for your next interview:

1. Container, Dependency, and IOC

2. Spring Bean Lifecycle

3. Aspect-Oriented Programming (AOP)

4. Spring MVC

5. Spring Boot Basics

6. Spring Boot Auto Configuration

7. Spring Boot Starter Dependency

8. Spring Boot Actuator

9. Spring Boot CLI

10. Spring Boot Testing

11. Spring Cloud Questions

12. Spring Data JPA

13. Spring Security

Now, let’s see a couple of frequently asked questions from each topic to review essential concepts:

1. Container, Dependency, and IOC

This topic is focused on spring container basics and the key benefits of IOC and Dependency injection and how Spring Framework implements them, here are some sample questions from this topic

What are dependency injection and IOC? How Spring MVC implements them? (answer) What is applicationContext in Spring? (answer) What is the difference between BeanFactory and Application Context?
