  "textContent": "**Spring Boot** is the most widely used Java framework for building production server applications. Built on top of the broader Spring Framework, Spring Boot adds auto-configuration, an embedded application server, and a \"starter\" dependency system so developers can launch a working web application in minutes instead of wiring XML configuration by hand.\n\n## Core pieces\n\n  * **Auto-configuration.** Spring Boot inspects the classpath and configures beans automatically (data source, web server, security).\n  * **Starters.** Curated dependency groups: `spring-boot-starter-web`, `-data-jpa`, `-security`, `-actuator`, and many more.\n  * **Embedded server.** Tomcat, Jetty, or Undertow ships inside the application jar; one binary boots the app.\n  * **Spring Data.** Repository abstractions for JPA, MongoDB, Redis, Cassandra, and many other stores.\n  * **Spring Security.** Authentication and authorization with OAuth 2.0, OIDC, SAML, and method-level checks.\n  * **Actuator.** Production endpoints: health, metrics, info, env, threaddump, often integrated with Prometheus and Micrometer.\n\n\n\n## Where it fits\n\n  * Microservices in Java or Kotlin (Spring Boot is JVM)\n  * Enterprise back-ends needing mature security, transaction, and integration stories\n  * Reactive applications via Spring WebFlux\n\n\n\n🔗\n\n**Related Terms**\nREST API, Microservices, ORM, OAuth 2.0.",
