Spring Boot packages all dependencies and an embedded web server into a single executable JAR, allowing developers to launch the application with a simple "java -jar" command without external configuration or server deployment.
This article explains how Spring Boot packages applications as executable Fat JARs, embeds a web server, uses a special launcher, and defines a main class so the JAR can be run with a simple java -jar command, eliminating the need for separate deployment servers.
This article explains how Spring Boot's spring-boot-maven-plugin creates an executable JAR, describes the internal structure and Manifest, details the role of JarLauncher and the custom LaunchedURLClassLoader, and provides concrete code examples for class loading and execution.
