Introduction to Spring 5, Spring MVC, and Spring REST

SEE SCHEDULE

Duration: 5 Days

Method: Instructor led, Hands-on Workshops

Price: $2950.00

Course Code: SP1016



Audience

Java developers requiring a solid background in using the Spring framework.

Description

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. The course includes integration of Spring with Java EE Web applications, a solid introduction to Spring MVC, and coverage of building RESTful resources with Spring MVC. It also provides an overview of Springs reactive programming model for repositories and Web resources. You will build working Spring applications and gain an understanding of the important concepts and technology in a very short time (minimum 50% hands-on labs).The standard platform does all labs with the Eclipse IDE, but can be made available for all major development environments, including IBM RAD and IntelliJ.

Objectives

Upon successful completion of this course, the student will be able to:

  • 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
  • Build Web applications with Spring MVC, including configuration using Java config and Servlet 3 capabilities
  • Understand and use the core capabilities of Spring's Reactive programming support
  • Understand REST, and use Spring MVC to build RESTful services
  • Use Ajax-based front ends with Spring MVC / Spring REST
