Spring Tool Suite (STS) provides the development environment for Spring-powered enterprise applications. This can be easily downloaded from the Eclipse marketplace in the following manner:

Spring Boot is a quick and easy way to get up and running with production-grade standalone applications in no time. If you hated all the XML configurations required to be set for creating a Spring web application, Spring Boot helps us to get away with all those troubles, and lets us focus on developing the application from the word go. The following are some of the key attributes of a Spring Boot application:

In this section, we will go through the steps required to build a Hello World Web App using Spring Boot. The following given steps assume that you have set up Spring STS within your Eclipse IDE by following the steps given earlier. Now, with the steps given next, one can set up the Hello World web app in an easy manner:

        @Controller
@SpringBootApplication
        public class HelloWorldApplication {

@RequestMapping("/")
            String home() { 
                return "Hello world. How are you?";
            }

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

            spring.mvc.view.suffix=.jsp

            @Controller
@SpringBootApplication
            public class HelloWorldApplication {

@RequestMapping("/")
                String home() { 
                    return "index";
                }

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