Spring Boot Interview Questions - 2023
What is Spring Boot?
Spring Boot is an open-source framework that provides a pre-configured set of technologies and tools used to create web applications and services using the Java programming language. It is designed to make it easier to create and deploy applications by providing an intuitive and easy-to-use interface. Spring Boot is based on the Spring Framework, which is an enterprise Java framework used for creating enterprise applications.
What Are the Benefits of Using Spring Boot?
Spring Boot offers a number of advantages over traditional Java web development. It simplifies the development process by providing an intuitive and easy-to-use framework for creating web applications and services. It also provides a number of features that make it easier to develop and deploy robust applications quickly and efficiently. Some of the benefits of using Spring Boot include:
- It is fast to develop, deploy, and maintain applications.
- It is easy to integrate with other Java frameworks.
- It is secure and reliable.
- It is easy to customize and extend.
What Are the Different Types of Spring Boot Projects?
Spring Boot supports a number of different types of projects, including web applications, command line applications, and batch applications. Web applications are the most common type of Spring Boot project and are typically used to create web services and web-based user interfaces. Command line applications are used to create scripts that can be run from the command line. Batch applications are used to process large amounts of data in batches.
How Do You Create a Spring Boot Project?
Creating a Spring Boot project is relatively straightforward. The first step is to download and install the Spring Boot CLI (Command Line Interface). Once the CLI is installed, the next step is to create a project directory, which can be done using the command line. Once the project directory is created, the next step is to create a project file in the project directory. The project file contains the configuration for the project, including the dependencies, configuration settings, and any other information needed to create the project.
What Is the Spring Initializr?
The Spring Initializr is an online tool that can be used to create Spring Boot projects quickly and easily. The tool allows users to select the type of project to be created, the dependencies to be included, and the configuration settings to be used. The Spring Initializr then generates the project file and all of the necessary files and directories.
What Are Some Commonly Used Spring Boot Dependencies?
Spring Boot projects typically use a number of different dependencies to provide the necessary features and functionality. Commonly used dependencies include the Spring Framework, Spring Security, Hibernate, and Apache Tomcat. Other dependencies may be used depending on the type of project being created and the features required.
What Is the Spring Boot CLI?
The Spring Boot CLI (Command Line Interface) is a command line tool used to manage Spring Boot projects. The CLI can be used to create projects, manage dependencies, run tests, and deploy applications. The CLI is an essential tool for developers working with Spring Boot.
What Are the Key Features of Spring Boot?
Spring Boot provides a number of key features that make it easier to develop and deploy web applications and services. These features include an intuitive and easy-to-use framework, a robust set of tools, and a wide range of dependencies. Additionally, Spring Boot provides a number of features that make it easier to configure and customize applications, such as auto-configuration and custom starters.
