Introduction to Spring, Spring Boot & Spring Cloud

Course Objectives

Working in a hands-on learning environment, students will review configuration basics of the Spring framework. The course then moves into Spring Boot, providing in-depth content and experience working with Spring Boot to accomplish a variety of tasks. In addition to working through the Spring Actuator, students work extensively at testing and debugging Spring Boot applications.

Throughout the course you'll:

• Review the concept of Java-based configuration
• Become familiar with the conditionally loading bean definitions and Application Contexts
• Understand how to leverage the power of Spring Boot
• Use Spring Boot to create and work with JPA repositories
• Use Spring Boot to work in conjunction with Spring Cloud
• Understand the Spring Cloud project and how it relates to general Cloud concepts and practices
• Work with Spring Cloud configuration and the Config Client

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.
