Starting Spring Boot Application

First I will create the Maven Java Application using Netbean IDE.

Under the Project Files, you can see pom.xml file where you can add the project dependencies and and parent tag.

So your final pom.xml should be like this

    4.0.0
    com.codekayak
    BootStart
    1.0-SNAPSHOT
    jar
    
        UTF-8
        1.8
        1.8
    
    
    
        org.springframework.boot
        spring-boot-starter-parent
        1.5.9.RELEASE    
    
    
    
        
        
            org.springframework.boot
            spring-boot-starter-web
            1.5.9.RELEASE
        

    

Next, you can create the Test.java class and add the following code to it

package com.codekayak.bootstart;

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

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

Annotaion @SpringBootApplication tells to Spring that this is a Spring Boot application

Now you can build the application and run it

When you look at the console log of the Netbeans IDE you can see the Tomcat started on port(s): 8080 (http). This means we have build the stand alone application and we did not deploy it to Tomcat webserver.
So you can open this URL http://localhost:8080/ in your browser
