Core Spring 5.x and Spring Boot 2.x Quick Start (TT3320)

Course Objectives

Core Spring 5.x Quick Start | Introduction to Spring Essentials is a comprehensive hands-on introduction to Spring training course geared for experienced Java developers who wish to explore the Spring Framework is in terms of today's systems and architectures, and learn how to use Spring in conjunction with other technologies and frameworks.  Students will gain hands-on experience working with Spring, using Maven for project and dependancy management, and, optionally, a test-driven approach (using JUnit) to the labs in the course.

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 course.   The course then moves into the areas of persistence and transactions, looking at various options. 

Our engaging instructors and mentors are highly experienced practitioners who bring years of current "on-the-job" application development and Spring experience into every classroom.  Working in a hands-on learning environment, led by our expert practitioner, students will:

• Explain the issues associated with complex frameworks such as JEE and how Spring addresses those issues
• Understand the relationships between Spring and JEE, AOP, IOC and JDBC.
• Write applications that take advantage of the Spring container and the declarative nature of assembling simple components into applications.
• Understand how to configure the Spring Boot framework
• Understand and work on integrating persistence into a Spring application
• Explain Spring's support for transactions and caching
• Work with Spring Boot to facilitate Spring setup and configuration
• Apply Aspect Oriented Programming (AOP) to Spring applications

Need different skills or topics?  If your team requires different topics or tools, additional skills or custom approach, this course may be further adjusted to accommodate.  We offer additional Spring,  Java / JEE / Java for Web programming, Services, REST, TDD / testing, design, application security and other related topics that may be blended with this course for a track that best suits your needs. Our team will collaborate with you to understand your needs and will target the course to focus on your specific learning objectives and goals.
