How to setup Spring Boot RESTful API in 5 minutes

1. Use Spring initializr to create a backbone of the project. (https://start.spring.io/)

GroupID: unique identifier of your project. Often reversed company domain name. Ex) sandbox.com → com.sandbox

ArtifactID: name of the jar file without version.

** Add Spring Web on your dependencies. Spring Web provides embedded tomcat by default.

2. Create Controller and POJO.

** It uses Jackson JSON internally. So I don’t have to convert POJO into JSON.

3. Run Spring Boot!

• run application

./gradlew bootRun

• build and run jar file

./gradlew build
java -jar build/libs/pilot-0.0.01-SNAPSHOT.jar

IDE can provide such commands in button form.

Official Documentation is on: https://spring.io/guides/gs/rest-service/

It was nice to NOT configure tomcat, and Jackson JSON conversion, which where two hurdles I have faced coming from Node.js background.
