Build a strong foundation in enterprise Java development with Spring Core Training, a practical course designed for developers who want to understand the fundamental technologies and architecture behind the Spring Framework. The training provides the essential knowledge needed to develop flexible, maintainable, and testable Java applications using Spring.
Course Overview:
This course offers hands-on experience with the major features of Spring and Spring Boot, which includes configuration, data access, REST, AOP, auto-configuration, actuator, security, and Spring testing framework to build enterprise and microservices applications. On completion, participants will have a foundation for creating enterprise and cloud-ready applications.
Course Objectives:
Upon completion of this course, participants will understand how to implement the following:
- Spring configuration using Java Configuration and Annotations
- Aspect oriented programming with Spring
- Testing Spring applications using JUnit 5
- Spring Data Access – JDBC, JPA and Spring Data
- Spring Transaction Management
- Simplifying applications with Spring Boot
- Spring Boot auto-configuration, starters and properties
- Build a simple MVC application using Spring Boot, embedded Web Server and fat JARs or classic WARs
- Implementing REST with Spring MVC and RestTemplate
- Spring Security
- Enable and extend metrics and monitoring capabilities using Spring Boot actuator
- Utilize Spring Boot enhancements to testing
Pre-requisites:
