Published by Pearson

Intermediate content levelIntermediate

Hands-on training for creating industrial-strength Spring Boot Applications

  • Taught by experienced author and trainer Andy Olsen
  • Exercises in every section
  • Weekly assignments with online solutions with real-world projects you can use in your own work

Spring Boot is a tremendously important framework and platform for creating enterprise applications that embrace REST services, database integration, messaging, security, testing, containerization, and deployment on-premise or on the cloud. Learning Spring Boot is difficult, and it’s important to learn in a pragmatic way while practicing real-world skills.

This 3-week course is designed to teach you from the ground up. Each week includes deep-dive training with Q&A and hands-on exercises so you can see real projects in action. You are given a homework assignment so you can test your own skills and learn by doing. This is an active class designed to give you the knowledge and the practical skills you need to benefit from all the best that Spring Boot has to offer. You learn how to use the eclectic mix of Spring Boot technologies to create robust, reliable, and performant industrial-scale applications efficiently and according to accepted best practices.

Is extensively hands on in nature

Uses a combination of instructional training and working demos to illustrate key topics Is accompanied throughout with hands-on exercises so you can have a go during the class Includes weekly assignments so you can apply your new-found knowledge in realistic and holistic scenarios Includes full online solutions for all assignments, as well as a full walkthrough and a Q&A session so you can clarify any details with Andy

Week 1

Sets you up with the core knowledge you need to get started creating Spring Boot applications. Learn how to define component classes, manage bean dependencies and lifetimes, and define Java configuration classes. Challenge yourself with a homework assignment that will put your learning into action.

Week 2

Is all about creating enterprise-scale Spring Boot applications. This week starts with showing how to integrate data sources into a solution, by using JPA and Spring Data repositories. You then learn how to define and consume REST services, to enable communication between distributed applications. The week then ends with a practical hands-on assignment.

Week 3

Rounds out the training by taking you to the next level with industrial-strength Spring Boot technologies and techniques. You learn about the importance of messaging in real-world applications and see how to use Kafka to create efficient and performant message-based solutions. Learn how to containerize a Spring Boot application using Docker and see how this can help you create a microservice architecture. Finally, you see how to secure and test your application to ensure it operates safely and correctly.

At the end of the session we’ll provide a thorough tutorial that guides you through all the steps to create a complete Spring Boot application with all the features covered during the 3 weeks. Full step-by-step solutions will be available online so you can check your progress.

What you’ll learn and how you can apply it

  • Creating Spring Boot web applications
  • Managing Spring Boot beans, properties, and application configuration
  • Creating and consuming REST services
  • Integrating with relational databases
