How does Spring Boot design and structure a web application during build?

Spring Boot automatically structures a web application during project build, using conventions and built-in settings. Key points:

• Automatic configuration — Spring Boot scans dependencies and configures components (e.g., web server, databases) without manual setup.
• Standard directory structure — source code is located in src/main/java, resources in src/main/resources.
• Embedded server — a runnable JAR with an embedded server (Tomcat, Jetty) is created during build, simplifying application launch.
• Configuration files — application.properties or application.yml are used to set application parameters.

Thus, Spring Boot simplifies creating and packaging web applications, allowing quick deployment of a ready service without complex infrastructure setup.
