Basic Spring Boot Application Example

Basic Spring Boot Application Example:

We have already went through various examples using spring, To understand spring please refer here.

What is Spring Boot?
Spring Boot is a way to create stand-alone applications with less or no configurations and has defaults for annotation configuration which we will use in our application

Advantages of Spring Boot:

• Reduces development time
• Embedded Servers
• No XML configuration
• Integration with Spring JDBC, Spring ORM etc.

Now let us see an basic example to create spring boot application in Netbeans.

Structure:

SpringBootApp.java

package javainfinite.springboot;

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

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

Output:

We have created basic spring boot application!
