Java Training : Introduction to Spring 5

Introduction to Spring 5

Java Training Overview

Spring 5 provides an evolutionary advance of Spring�s powerful capabilities. This course introduces these capabilities, as well as providing guidelines on when and how to use them. It includes coverage of the three main configuration styles: Java-based (@Configuration), annotation-based (@Component), and the traditional XML-based configuration that may still play an important role in existing and new projects.

The course starts with in-depth coverage of Spring�s Core module to reduce coupling and increase the flexibility, ease of maintenance, and testing of your applications. It goes on to cover many of the most important capabilities of Spring, including easing configuration with Spring Boot, integrating Hibernate and JPA persistence layers with Spring and Spring Data, and using Spring�s declarative transaction capabilities.

This course is hands on with labs to reinforce all the important concepts. It will enable you to build working Spring applications and give you an understanding of the important concepts and technology in a very short time.

Java Training Skills Gained

Understand the core principles of Spring, and of Dependency Injection (DI) / Inversion of Control
Use the Spring Core module and DI to configure and wire application objects (beans) together
Know the different types of metadata (XML, annotations/@Component, and Java Configuration/@Configuration), and how and when to use them
Understand and use the complete capabilities of the Core module, such as lifecycle events, bean scopes, and the Spring API
Use Spring Boot to simplify dependency management and configuration
Work with the ORM (Object-Relational Mapping) module to integrate Spring with technologies such as Hibernate or JPA.
Use Spring Data to automatically generate JPA-based repository classes
Understand and use Spring�s transaction support, including the easy-to-use Java annotation support, as well as the tx/aop XML configuration elements
Integrate Spring with Java EE Web applications
