Course Description
Overview
Hands-On Core Spring: Explore Spring Essentials, Spring Boot, Spring AOP, Spring Data, Spring REST & More.Mastering Spring 5.x is a hands-on Spring training course geared for experienced Java developers who need to understand what the Spring Framework is in terms of today's systems and architectures, and how to use Spring in conjunction with other technologies and frameworks. This leading-edge course provides added coverage of Spring's Aspect-Oriented Programming and the use of Spring Boot. It includes complete coverage of all new features in Spring 5.x. Students will gain hands-on experience working with Spring, using Maven for project and dependency management, and, optionally, a test-driven approach (using JUnit) to the labs in the
course.
The Spring framework is an application framework that provides a lightweight container that supports the creation of simple-to-complex components in a non-invasive fashion. Spring's flexibility and transparency is congruent and supportive of incremental development and testing. The framework's structure supports the layering of functionality such as persistence, transactions, view-oriented frameworks, and enterprise systems and capabilities.
This course targets Spring 5.x. Spring supports the use of lambda expressions and method references in many of its APIs. Spring simplifies common tasks and encourages good design based on programming to interfaces. Spring makes your application easier to configure and reduces the need for many JEE design patterns. Spring puts the OO design back into your JEE application, and it integrates nicely with many view technologies and the new features of HTML5.
This course provides a solid understanding of what Spring brings to the table and how to use Spring in the context of other technologies and frameworks. Students are taken on an in-depth tour of the basic Spring framework, initially examining concepts such as Inversion of Control and Dependency Injection, and then working with the container and basic components. Students are introduced to Spring Boot and use Spring Boot throughout the remainder of the course. The latter part of the class looks at implementing REST with Spring and takes a deep dive into Spring Boot to prepare students for more extended Spring Boot usage following class.
Objectives
After completing this course, students will be able to:
- Explain the issues associated with complex frameworks such as JEE and how Spring addresses those issues
- Write applications that take advantage of the Spring container and the declarative nature of assembling simple components into applications.
- Understand how to configure the framework Spring Boot and various options within Spring Boot for detailed configuration.
- Understand and work on integrating Sprint Data into a Spring application.
- Develop REST applications using Spring 5
- Work with Spring Boot to facilitate Spring setup and configuration
Audience
This class is geared for experienced Java developers who are new to Spring, who wish to understand how and when to use Spring in Java and JEE applications.
