Setting up dependencies for building RESTful services


In this recipe, we will lay the foundation for developing the RESTful service. We will see how to set up dependencies and run our first SpringBoot web application. SpringBoot provides great support for Kotlin, which makes it easy to work with Kotlin. So let's get started.

Getting ready

We will be using IntelliJ IDEA and Gradle build system. If you don't have that, you can get it from https://www.jetbrains.com/idea/.

How to do it…

Let's follow the given steps to set up the dependencies for building RESTful services:

  1. First, we will create a new project in IntelliJ IDE. We will be using the Gradle build system for maintaining dependency, so create a Gradle project:
  1. When you have created the project, just add the following lines to your build.gradle file. These lines of code contain spring-boot dependencies that we will need to develop the web app:
buildscript {
    ext.kotlin_version = '1.1.60' // Required for Kotlin integration
    ext.spring_boot_version...
