Spring makes programming in Java faster, easier, and safer. Its speed, simplicity, and productivity have made Spring the most popular Java framework in the world. During this training, participants will learn the architecture of the framework, be guided step by step through the most important Spring modules, and gain hands-on experience in quickly creating a web application with it.
What will you learn?
- You will understand the architecture of Spring Framework – starting with Spring Core, moving on to Spring Boot configuration improvements, and exploring key modules such as Spring Web and Spring Data
- You will learn how to configure applications (and why they should be configured in specific ways)
- You will practice how to expose REST services in Spring, handle and validate data, manage errors, and consume APIs from other services
- You will gain hands-on experience working with databases using Spring Data
- You will learn to write unit and integration tests with Spring Test
- You will discover best practices for managing code and project structure in web application development
Benefits of the Spring Framework
- No need to worry about configuring each infrastructure component – Spring handles it, allowing you to focus on business logic
- Ability to deliver MVPs quickly
- Thanks to its consistent programming model, adopting new technologies within Spring applications feels natural and straightforward
