A General Overview to Spring Boot

Spring Boot is a new project from The Spring Team, Spring Boot is their latest innovation to keep up to date with modern technology’s needs. Spring Boot made it easier to create stand-alone and its applications need very little spring configuration. It does not generate code and there is absolutely no requirement for XML configuration.

Since I am writing article on Spring Boot, I am assuming that you already know basic concepts of Java language and particularly familiar with Spring Framework. Spring framework is based on Java language and Spring Boot is a new Module of Spring framework that provides Rapid Application Development or RAD. So, guys head up now for an amazing learning experience on Spring Boot in this short period of time.

Introduction

Spring Boot offers a new way of developing Spring applications with minimal code. Using Spring Boot, we are able to develop Spring applications that focuses on addressing your application’s functionality needs with minimal configuration. Spring Boot is advance module of Spring which provides RAD (Rapid Application Development) feature to Spring Framework. It uses the new development model that makes Java Development straightforward and easy by avoiding some serious development steps and code configurations. With Spring Boot, it’s easy to create stand-alone, production-grade Spring based Applications that we can “just run” without much sort of configurations.

Spring Boot able to develop stand-alone application with less code configurations. It provides by default code configurations and annotations for new projects. Spring Boot generally focuses on Spring projects as well as third-party projects to develop product-ready applications. The absolute advantage of Spring Boot is that it automatically configures required libraries depending on the class path.

Spring Boot Goals

· Spring Boot provides an easy way to get started with the applications.

· It avoids writing lots of import statements and defining Annotation configuration.

· Spring Boot let you avoid complex XML configuration statements in Spring.

· It offers the applications to run independently by reducing development time.

Creating a Spring Boot Application

Creating a Spring Boot application is not a tedious task, you need to following tools to setup a new application:

· Java 1.8

· Maven 3.0+ or Gradle 2.3+

· Spring Framework 5.0

· Spring Tool Suite IDE

To create your first Spring Boot application,

start the Spring Tool Suite > Click on File > New > Click Spring Starter project to open the project creation wizard.

Open your project and create a new controller class named HelloController.java in your predefined package.

HelloController.java

package com.new.example;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class HelloWorldController {
@RequestMapping("/")
@ResponseBody
String index() {
return "Hello, World!";
}
}

Start the application as a Spring Boot App with Apache Tomcat server with port 8080 configured at the time of server installation. Open your browser with http://localhost:8080 and you will see the output message as

· Increases productivity and reduces development time.

· Provides web servers like Apache Tomcat to develop and test web-based applications.

· It provides lots of plugins and add on tools like Gradle and Maven to develop and test Spring applications.

· It provides easy integration with third party applications as well to maintain the Spring Ecosystem.
