Spring Boot and CircleCI are a powerful combination for implementing continuous integration (CI) in the cloud. This guide provides an introduction to integrating Spring Boot with CircleCI, explains the benefits of cloud-based CI, and offers sample code with explanations for setting up automated builds and tests.

Why Use CircleCI with Spring Boot?

CircleCI is a cloud-based continuous integration and continuous delivery (CI/CD) platform that automates building, testing, and deploying software. When integrated with Spring Boot, it offers several advantages:

  • Cloud-Based Automation: CircleCI provides a cloud-based CI/CD platform that eliminates the need for on-premises infrastructure, making it easy to scale and manage your CI pipeline.
  • Automated Builds: CircleCI can automatically build your Spring Boot applications whenever changes are pushed to a version control system, ensuring that the code is always in a deployable state.
  • Continuous Testing: CircleCI enables automated testing of your Spring Boot application, including unit tests, integration tests, and other types of tests, ensuring software quality.

Setting Up Automated Builds and Tests with CircleCI

To set up automated builds and tests for your Spring Boot project with CircleCI, follow these steps:

  1. Create a CircleCI configuration file (`.circleci/config.yml`) in the root of your Spring Boot project.
# .circleci/config.yml
version: 2
- image: circleci/openjdk:11
- checkout
- run:
name: Build and Test
command: |
./gradlew clean build
- store_test_results:
path: build/test-results
- store_artifacts:
path: build/libs

In this example, we define the job to use an OpenJDK 11 Docker image, specify build and test steps, and store test results and artifacts. Adjust these settings according to your project's requirements.

  1. Enable the CircleCI service for your project on the CircleCI website ( and connect it to your version control system (e.g., GitHub).
  1. Push your project to the repository on GitHub. CircleCI will automatically detect the `.circleci/config.yml` file and start the build and test process.


Spring Boot and CircleCI provide a powerful platform for implementing automated builds and tests in the cloud, automating the CI/CD pipeline. This guide introduced the integration, explained the benefits of cloud-based CI, and provided sample code for setting up automated builds and tests. As you delve deeper into cloud-based CI/CD processes, you'll find that they significantly improve software development efficiency and reliability.
