spring-boot

To create a Spring Boot project, use Spring Initializr or the CLI to generate a project structure, then add web and data-jpa dependencies to enable REST controllers and database access. This simplifies project setup and auto-configuration.

Auto-configuration in Spring Boot automatically configures application beans based on dependencies on the classpath. It works by scanning libraries and applying default settings, reducing manual XML and Java configuration for web development and data access.

Configure a database connection in Spring Boot by defining datasource properties in application.properties or application.yml. This manages database settings for JPA, allowing seamless data access and CRUD operations for entities like a PostgreSQL connection.

Yes, you can use Spring Boot for microservices and REST API backend development. It provides embedded servers, dependency injection, and REST controllers, enabling rapid setup and deployment of standalone Java microservices.

Implement CRUD operations in Spring Boot by defining a JPA entity for the user and creating a repository interface. This provides standard data access methods, simplifying database interactions without writing boilerplate SQL.

Yes, Spring Boot includes Spring Security for configuring authentication and authorization in Java web applications. It provides auto-configured security defaults that protect REST endpoints and manage access control.
