What are the common spring boot
interview questions in 2023?
Java programmers can use Spring Boot to create standalone, production-ready spring
applications that you can easily execute. Without the requirement for a full setup of Spring
configuration, you can get started with the bare minimal configurations.
Advantages
The benefits that Spring Boot provides to its developers are as follows:
●
●
●
Simple to comprehend and create easy spring applications
productivity rises
Has the ability to reduce the development time
Goals
The objectives of Spring Boot's design are as follows:
●
●
●
●
To keep Spring's XML settings simple
Easily create production-ready Spring apps
To speed up application development and make it independent
Describe a simpler approach to launch the program.
These are the briefings that we want our viewers to know before they start looking for some
of the most asked spring boot interview questions.
What is the definition of Spring Boot?
In essence, Spring Boot is an addition to the Spring framework that goes with the
configurations needed to build up a Spring application. An opinionated framework called

What other approaches are there to building a Spring boot application?
There are many approaches to creat a Spring Boot project
1. Using Spring Initializr - Use any IDE, such as Eclipse STS, Eclipse, IntelliJ Idea,
VSCode, or Netbeans, to create a Spring boot project using Spring Initializr.
2. Using Spring Starter Project in STS (Eclipse) - Using the Spring Starter Project option
in STS, you may instantly create a Spring boot project.
3. Spring Boot CLI - If you want to create a Spring application quickly, you can use the
Spring Boot CLI command-line tool.
Why will you choose Spring Boot?
You can select Spring Boot due to the characteristics and advantages it provides, which are
listed here.
●
It offers a versatile approach to set up XML configurations, database transactions,
and Java Beans.
●
It maintains REST endpoints and offers strong batch processing.
●
Nothing needs to be manually configured with Spring Boot; everything is
automatically configured.
●
It provides a spring application based on annotations.
●
manage dependencies more easily
●

Starting Spring Boots
For large projects, handling dependency management is a challenging issue. By offering a
set of dependencies for developers' convenience, Spring Boot solves this issue.
For instance, adding the spring-boot-starter-data-JPA dependency to your project is
sufficient if you wish to use Spring and JPA for database access.
Adaptive Configuration
With Spring Boot Auto Configuration, your Spring application is automatically configured
depending on the JAR dependencies you supplied to the project. For instance, if your
classpath includes the MySQL database but you haven't set up a database connection,
Spring Boot will automatically set up an in-memory database.
What characteristics does Spring Boot have?
Here are a few key aspects of Spring Boot below.
1. Logging and security
All of the apps created by Spring Boot would be secure; thanks to this capability.
2. Spring Initializer
It is an application that will lessen the amount of manual labour you have to do when setting
up the project's structure.
3. Spring Boot CLI
Your manual work writing boilerplate code and annotation will be reduced using the Spring
CLI.
4. Spring Boot Actuator
You can monitor and manage the Spring Boot apps with the aid of this Spring Boot
framework subsidiary project.
