CI/CD pipeline basics in Spring Boot

Introduction

A CI/CD pipeline helps automate building, testing, and delivering your Spring Boot app. It saves time and reduces mistakes.

When you want to automatically test your Spring Boot app after code changes.

When you want to build your app and create deployable packages without manual steps.

When you want to deploy your app to a server or cloud automatically after tests pass.

When multiple developers work on the same Spring Boot project and need quick feedback.

When you want to deliver updates to users faster and more reliably.

Syntax

Spring Boot

pipeline {
  agent any
  stages {
    stage('Build') {
      steps {
        sh './mvnw clean package'
      }
    }
    stage('Test') {
      steps {
        sh './mvnw test'
      }
    }
    stage('Deploy') {
      steps {
        echo 'Deploying application...'
      }
    }
  }
}

This example uses Jenkins pipeline syntax for a Spring Boot app.

Each stage runs commands like building, testing, and deploying.

Examples

This stage builds the Spring Boot app using Maven wrapper.

Spring Boot

stage('Build') {
  steps {
    sh './mvnw clean package'
  }
}

This stage runs automated tests to check code quality.

Spring Boot

stage('Test') {
  steps {
    sh './mvnw test'
  }
}

This stage would deploy the app; here it just prints a message.

Spring Boot

stage('Deploy') {
  steps {
    echo 'Deploying application...'
  }
}

Sample Program

This Jenkins pipeline builds, tests, and deploys a Spring Boot app automatically.

Spring Boot

pipeline {
  agent any
  stages {
    stage('Build') {
      steps {
        sh './mvnw clean package'
      }
    }
    stage('Test') {
      steps {
        sh './mvnw test'
      }
    }
    stage('Deploy') {
      steps {
        echo 'Deploying Spring Boot app...'
      }
    }
  }
}

Important Notes

Make sure your Jenkins agent has Java and Maven installed to run these commands.

Use './mvnw' to run Maven wrapper included in Spring Boot projects for consistent builds.

Deploy stage can be customized to upload your app to servers or cloud platforms.

Summary

CI/CD pipelines automate building, testing, and deploying Spring Boot apps.

They help catch errors early and speed up delivery.

Jenkins pipelines use stages to organize these steps clearly.
