Spring Boot Development

In the course Spring Boot Development you will learn to develop applications and microservices with Spring Boot in a fast and efficient way.

Spring Intro

The course starts with an overview of the most important Spring principles such as loading beans in the bean container and dependency injection.

Spring Boot

Subsequently it is discussed how predefined configurations in Spring Boot act as a starting point for a Spring Boot application. Other main components of Spring Boot are also discussed, such as the Autoconfigurator, the Actuator and the Command Line Interface (CLI).

Dependency Injection

Dependency injection with its associated annotations such as @Component, @Qualifier, @Repository and @Service is treated in detail. The internal workings of dependency injection based on Java Reflection is also explained.

Application Configuration

Also part of the course program are the auto configuration options in Spring Boot. Components can be linked with annotations such as @EnableAutoConfiguration if registered in classes annotated with @Configuration.

Aspect Orientation

And Aspect Orientation in Spring Boot is discussed as well. Crosscutting concerns in an application such as security or profiling can thus be included in so called aspects without disrupting the main program flow.

Spring JDBC and Spring Data

Database access from Spring Boot applications is covered in the modules Spring JDBC and Spring Data. Various Spring templates that help prevent boilerplate code such as jdbcTemplate and MongoTemplate as well as JPA repositories are discussed.

Spring REST

Spring Boot is ideally suited to access REST APIs with compact code. The various annotations that are important here, such as @RestController, @ResponseStatus and @JsonView, are treated.

Spring Extensions

Finally various Spring extension projects are covered such as Spring Security and Spring Cloud.

Audience Spring Boot Development

The course Spring Boot Development is intended for experienced Java Developers who want to use Spring Boot for application development.

Prerequisites Course Spring Boot Development

Experience with programming in Java and object orientation is required to participate in this course. Basic knowledge of the Spring Framework is beneficial to good understanding.

Realization Training Spring Boot Development

The concepts are treated on the basis of presentations and demos. The theory is interspersed with exercises. The course times are from 9.30 to 16.30.

Certification Spring Boot Development

Participants receive an official certificate Spring Boot Development after successful completion of the course.
