Spring Boot Main Class Guide

When writing a Spring Boot startup class, it is important to follow certain conventions and standards. Typically, a Spring Boot startup class is a Java class annotated with @SpringBootApplication.

Here is a simple example of a Spring Boot startup class:

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MySpringBootApplication {

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

In the example above, the @SpringBootApplication annotation is used to identify the main class of a Spring Boot application. The main method serves as the entry point of the program, starting the Spring Boot application by calling the SpringApplication.run method.

In practical development, the main application class usually also contains additional configurations, such as scanning components in specific packages and setting properties. Depending on the specific requirements, corresponding annotations and configurations can be added to the main application class.
