Spring Boot Project using Spring Starter Project Wizard

We are using Eclipse IDE for the below example. It is very popular IDE for java projects. You can download it from here.

Let’s get started :

Step 1 : Create a new Spring Starter Project

Go to File >> New >> Spring Starter Project :

Provide the required details about Project and click on Next:

Now, search the web in the dependencies and check the Spring Web dependency and click on Finish :

Now, the Spring Boot Project is automatically created with the below pasted pom.xml file :

pom.xml :

<project

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>
</project>

Also Spring Boot Starter wizard has also created the main app class for our Project :

Step 2 : Create the controller for Hello World Example

Now, create class inside the src/main/java package in your project :

Now,

Add the @Controller annotation class level.
Create a method that returns String .
Add @RequestMapping(“/”) and @ResponseBody annotation at this method.

@Controller indicates that class is a Controller.
@RequestMapping annotation maps HTTP requests to handler methods of controllers.
@ResponseBody is annotation which binds the method return value to the web response body.
