Starters

Spring Boot Starters are a set of convenient dependency descriptors that you can include in your Spring Boot application's build configuration (e.g., Maven pom.xml or Gradle build file). These starters simplify the process of configuring and bootstrapping various aspects of your Spring Boot application by providing pre-configured dependencies.

Spring Boot Starters are designed to handle specific functionality or integrate with particular technologies, frameworks, or libraries commonly used in Spring-based applications. By including a starter in your project, you bring in all the necessary dependencies and configurations to enable that functionality without needing to manually manage dependencies or configuration details.

Some common Spring Boot starters include:

spring-boot-starter-web: Includes dependencies for building web applications using Spring MVC, including Tomcat as the default embedded container.
spring-boot-starter-data-jpa: Provides dependencies for Spring Data JPA, which simplifies the implementation of data access layers in Spring applications.
spring-boot-starter-security: Includes dependencies for securing Spring applications using Spring Security.
spring-boot-starter-test: Contains dependencies for testing Spring Boot applications, including JUnit, Spring Test, Mockito, and AssertJ.
spring-boot-starter-actuator: Adds production-ready features to monitor and manage your application, including health checks, metrics, and more.
spring-boot-starter-logging: Configures logging for your Spring Boot application, typically using Logback or Log4j2.
spring-boot-starter-cache: Provides dependencies for integrating caching support into your Spring application.
spring-boot-starter-mail: Includes dependencies for sending emails using Spring's email support.
spring-boot-starter-data-rest: Enables building RESTful web services using Spring Data REST.
spring-boot-starter-oauth2-client: Adds OAuth2 client support to your Spring Boot application.
