Spring Boot does not have any code layout to work with. However, there are some best practices that will help us. This chapter talks about them in detail.
Default package
A class that does not have any package declaration is considered as a default package. Note that generally a default package declaration is not recommended. Spring Boot will cause issues such as malfunctioning of Auto Configuration or Component Scan, when you use default package.
Note − Java's recommended naming convention for package declaration is reversed domain name. For example − com.javahubpoint.myproject
Typical Layout
The typical layout of Spring Boot application is shown in the image given below −
Typical Layout of Spring Boot Application
The Application.java file should declare the main method along with @SpringBootApplication. Observe the code given below for a better understanding −
package com.javahubpoint.myproject;
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);}
}
