How is a secure connection established using SSL/TLS protocols? What are the steps involved?

Launching a Spring Boot application involves the following steps:

1. Application context initialization — Spring Boot creates and configures the ApplicationContext, which manages the lifecycle of beans.

2. Automatic configuration — Spring Boot analyzes dependencies and settings, automatically configuring components and services.

3. Component scanning — searching for classes with annotations (@Component, @Service, @Repository, @Controller, etc.) to create beans.

4. Starting the embedded server (e.g., Tomcat or Jetty) — if the application is web-based, the server starts automatically.

5. Executing the main method — the entry point where SpringApplication.run() is called, initiating the entire process.

Example of a simple Spring Boot application startup:

@SpringBootApplication
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

Thus, Spring Boot simplifies the startup and configuration of applications, minimizing manual setup.
