Using Spring Boot —— Structuring Your Code

 

1. Use the default package.

　　Do not scan the next class in the default package

 

2. Main Application Class

　　Use SpringBootApplication annotation, which contains the following three notes:

• @EnableAutoConfiguration: enable Spring Boot’s auto-configuration mechanism
• @ComponentScan: enable @Component scan on the package where the application is located (see the best practices)
• @Configuration: allow to register extra beans in the context or import additional configuration classes

　　

package com.example.myapplication;

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

@SpringBootApplication
public class Application {

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

}
