Spring Boot , Hello World Example

Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run".
We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration.
Features

• Create stand-alone Spring applications
• Embed Tomcat, Jetty or Undertow directly (no need to deploy WAR files)
• Provide opinionated 'starter' dependencies to simplify your build configuration
• Automatically configure Spring and 3rd party libraries whenever possible
• Provide production-ready features such as metrics, health checks and externalized configuration
• Absolutely no code generation and no requirement for XML configuration

Technologies stack:

• Spring Boot 2.1.3.RELEASE
• Maven
• JDK 1.8

Create Project:

To Create Project with spirng boot use https://start.spring.io/ which allow you to dowload .zip files. After download extract and import with IDE.

Need to Add high lighted Dependency manually to run jsp 

Run Application: 

Now Run Main Class (where public static void main method define) from base package, In our case we have "SpringHelloWorldApplication", It will run tomcat with port 8080

http://localhost:8080/

It is better to conquer yourself than to win a thousand battles. Then the victory is yours. It cannot be taken from you, not by angels or by demons, heaven or hell.
