Spring Boot Interview Questions and Answers - English
Here are some common Spring Boot interview questions along with their answers: What is Spring Boot? Spring Boot is an open-source Java-based framework used to create stand-alone, production-grade Spring-based applications with minimal setup and configuration. What are the key features of Spring Boot? Some key features include: Auto-configuration: It automatically configures the Spring application based on dependencies present in the class path. Starter dependencies: Pre-configured dependencies to simplify dependency management. Embedded servers: It provides support for embedding servlet containers like Tomcat, Jetty, and Undertow. Production-ready features: It includes features like metrics, health checks, and externalized configuration. Explain the difference between Spring and Spring Boot. Spring is a comprehensive framework for building enterprise-level Java applications, while Spring Boot is an extension of the Spring framework that simplifies the process of building and deploying Spring applications by providing defaults for configuration and eliminating boilerplate code. How does Spring Boot simplify the development process? Spring Boot simplifies development by providing defaults for configuration, reducing the amount of boilerplate code, and offering a range of pre-built features and plugins. What is Spring Boot Starter? Spring Boot Starter is a set of convenient dependency descriptors that you can include in your application. You can add starters to your application's class path, and Spring Boot will automatically configure the appropriate dependencies based on the libraries present. How does Spring Boot handle configuration? Spring Boot uses convention over configuration and auto-configuration to minimize the need for explicit configuration. It provides sensible defaults for configuration and automatically configures components based on the classpath and application properties. What is Spring Boot Actuator? Spring Boot Actuator is a set of production-ready features that help you monitor and manage your application. It includes endpoints for health checks, metrics, info, environment details, and more. Explain the difference between @Component, @Service, @Repository, and @Controller annotations in Spring Boot. @Component is a generic stereotype annotation for any Spring-managed component. @Service is used to mark a class as a service component in the business layer. @Repository is used to mark a class as a data access component in the persistence layer. @Controller is used to mark a class as a controller component in the presentation layer, typically for handling HTTP requests. How does Spring Boot support testing? Spring Boot provides support for unit testing, integration testing, and end-to-end testing using frameworks like JUnit, Mockito, and Spring Boot Test. It includes features like @SpringBootTest annotation for loading Spring application contexts, @MockBean annotation for mocking beans, and TestRestTemplate for testing RESTful endpoints. What is Spring Boot CLI? Spring Boot CLI (Command Line Interface) is a command-line tool that allows you to quickly develop Spring Boot applications using Groovy scripts. It provides features like auto-restart, dependency management, and more, directly from the command line. These questions cover some of the fundamental aspects of Spring Boot that are commonly asked in interviews. Make sure to understand these concepts thoroughly and be prepared to provide examples or elaborate on them during interviews.
