Hire Spring Boot Developers
Spring Boot is an open-source framework for building enterprise-level applications using the Spring Framework. It provides a simplified and opinionated approach to configuring and building applications, which reduces the boilerplate code and helps developers focus on the core business logic.
Spring Boot simplifies the development process, allowing developers to focus on business logic rather than infrastructure configuration. Spring Boot's key features include embedded servers, auto-configuration, and production-ready metrics. Spring Boot developers are in high demand, and if you want to hire Spring Boot developers, you must understand the basics of the Spring framework.

Top 5 Spring Boot Interview Questions
What are the Spring Boot starters, and what are available starters?
This question assesses the candidate’s knowledge of Spring Boot's starter dependencies. The Spring Boot starters are a set of pre-configured dependencies that can be included in your project to set up a particular feature or technology quickly and easily. Some available starters are Spring Boot Starter Web, Spring Boot Starter Data JPA, Spring Boot Starter Security, and Spring Boot Starter Test.
The best answer would be to briefly explain what Spring Boot starters are and mention a few examples of available starters they've used in their projects. A good developer will also explain how these starters make it easier to set up a project and how they help to reduce boilerplate code.
What is the role of the Spring Boot Actuator, and how do you use it?
This question assesses the knowledge of Spring Boot Actuator, a set of production-ready features that can be added to your Spring Boot application. The perfect answer to this question would be to explain the Spring Boot Actuator and its role in monitoring and managing the application. You can ask for examples of some of the endpoints provided by the Actuator and discuss with the candidate how they would use them in a real-world scenario.
Can you walk through deploying a Spring Boot application on AWS?
This question assesses the candidate's ability to deploy a Spring Boot application to the cloud, specifically on AWS. The interviewer wants to know if they have experience deploying applications to spring cloud on AWS and understand the process.
The best answer would be to explain the process of deploying a Spring Boot application on AWS, starting with creating an EC2 instance, installing Java and other dependencies, configuring the security groups and network settings, and finally, deploying the application. A good developer will also mention any specific tools or services they've used to simplify the deployment process.
How do you test a Spring Boot application, and what testing frameworks do you use?
This question assesses the developer's knowledge of testing Spring Boot applications and in-depth knowledge of the testing frameworks they've used. The interviewer wants to know if the developer has experience testing Spring Boot applications and understands the different test types.
The best answer would be to explain the different tests you can use to test a Spring Boot application, such as unit tests, integration tests, and end-to-end tests. You can also ask about some testing frameworks such as JUnit, Mockito, and Selenium, and ask them to explain how they would use them to test a Spring Boot application.
What is the purpose of the application.properties file in a Spring Boot project?
This question assesses the candidate's knowledge of the configuration in Spring Boot applications. The application.properties file configures various settings in a Spring Boot application, such as the database connection settings, server port, and logging level.
The best course of answer would be to explain the purpose of the application.properties file and provide some examples of settings that can be configured in this file. A good answer also explains how they would use this file to override default settings in the Spring Boot framework and how they would manage environment-specific configurations.
