In this article, we will discuss how to use the OpenAI API with the Java Spring Framework to generate images with ChatGPT.

Before getting started, you will need to sign up for an API key on the OpenAI website “”.
Once you have your API key, you can start making requests to the API.

RestTemplate is a powerful and flexible library that allows you to easily send HTTP requests and handle the responses.

First, you’ll need to add the Spring RestTemplate library to your project. You can do this by adding the following dependency to your build.gradle file:

plugins {
id 'java'
id 'org.springframework.boot' version '3.0.1'
id 'io.spring.dependency-management' version '1.1.0'

group = 'com.openai'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'
