Introduction to Spring Boot and Spring Data
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.
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
- Become familiar with the conditionally loading of bean definitions and Application Contexts
- Understand how to leverage the power of Spring Boot
- Use Spring Boot to create and work with JPA repositories
- Define the persistence layer of an application using Spring Data
- Query for data using Spring Data JPA Queries
Course Prerequisites
This introduction to Spring development course requires that incoming students possess solid Java programming skills and practical hands-on Java experience. 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.
