Java Web Development and CI/CD Best Practices

5 days

Overview

In today’s fast-paced software development landscape, building robust web applications and automating workflows are critical skills for developers and engineers. Java, with its rich ecosystem and reliability, remains a cornerstone technology for creating scalable and secure web applications. Coupled with the power of modern frameworks like Spring Boot and best practices in Continuous Integration and Continuous Deployment (CI/CD), developers can deliver high-quality software faster and more efficiently.

This 5-day training program is designed to provide participants with a comprehensive understanding of Java web development and CI/CD practices. The program begins with the foundational concepts of Java and progressively dives into advanced topics such as database integration, dynamic templating, automated testing, containerization, and deployment. Each day builds upon the previous, ensuring a seamless learning experience that bridges theoretical concepts with practical applications.

Objectives

  • Learn the knowledge and skills to build robust and scalable web applications using Java and Spring Boot.
  • Learn to create dynamic, user-friendly web interfaces using templating engines like Thymeleaf.
  • Understand the core concepts and best practices of Continuous Integration and Continuous Deployment for automating builds, testing, and deployment processes.
  • Apply hands-on experience in setting up projects, integrating databases, securing applications, and deploying to cloud platforms.
  • Implement the best practices in coding, testing, containerization, and deployment to ensure maintainable and efficient workflows.

Methodology

  • Interactive Lectures
  • Hands-on Labs
  • Project
  • Live Demo
  • Group Discussion and Q&A
