Spring Boot REST Example

Spring Boot REST Example

In this REST example we will use same project that we created earlier.To create basic project, you can follow below link.

Spring Boot Project set up

After creating project right click on package and create one class, for example RestService

Add below code

package com.example.preparationforinterview.FirstSpringBootPreparation;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

public class RestService {	
	@RequestMapping(value = "/api", method = RequestMethod.GET)
	public String getMessage(@RequestParam("name") String name){
		return "Hello" + " " + name;		

If we have RestService on separate package then we need to include @Import({ RestService.class }) in spring boot class , in our example

@Import({ RestService.class })
public class FirstSpringBootPreparationApplication {

That's all we require, now right click on FirstSpringBootPreparationApplication and run as Java Application or spring boot app

It will start embedded tomcat and you can check that your service is mapped properly

Now hit http://localhost:8080/api?name=developer.We will get below output
