Prerequisites
Experience in creating applications with Spring or knowledge equivalent to that provided by the course "Spring training, developing enterprise applications (ref. SPG)".
Course schedule
1 A reminder of the classic Spring configuration
- Configuration via XML files, annotations or configuration classes.
- Setting configuration parameters, using PropertyPlaceholders.
- Configuration of the persistence layer, DataSource and EntityManagerFactory.
- Business layer and transaction configuration.
- Web layer configuration, Controller and RestController, Spring Security.
- Unit and integration testing: SpringTest, MockMvc.
Hands-on work
Appropriation of a classic Spring application that will be converted into a Spring Boot application in the following chapters.
2 Initializing a Spring Boot application
- The Spring ecosystem and its complex configuration.
- Principle of "convention over configuration".
- Starters and auto-configuration.
- Implementation of Spring Initializr, creation of a simple web application.
Hands-on work
Identification of starters corresponding to requirements, production of the skeleton of the future Spring Boot application.
3 Dependency and auto-configuration management
- Organization of Maven dependencies, transparent version management.
- Code structuring, best practices.
- Role of the @SpringBootApplication and @EnableAutoconfiguation annotations, the "application" class.
- Anatomy of an auto-configuration class, role of @Conditionnal annotations.
- Control auto-configuration, using application.properties and application.yml property files.
- Create your own auto-configuration classes.
Hands-on work
Reorganization of existing application packages, creation of an "application" class, control of automatic configuration to the needs of the existing application.
4 Designing a Spring Boot application
- Profile definition.
- Trace configuration: log4j2 versus logback.
- JPA and Spring Data JPA with Spring Boot.
- Spring MVC with Spring Boot.
- Configuration of embedded technical infrastructures (database, servlet container).
- REST API security configuration.
- Make development easier with Spring Boot DevTools.
Hands-on work
Implement technical infrastructures "embedded", maximize auto-configuration.
5 Testing a Spring Boot application
- Test auto-configuration.
- Test persistence with @DataJpaTest.
- Integration test with @SpringBootTest.
- Test REST APIs with @AutoConfigureMockMvc, @WebMvcTest and RestTemplate.
- Monitor a Spring Boot application with Actuator.
Hands-on work
Upgrade application unit and integration tests to new Spring Boot practices, monitor use of REST endpoints.
6 Packaging and deploying a Spring Boot application
- Creating a war for classic deployment.
- Creation of a "self-contained" executable jar.
- Deployment in a docker image.
Hands-on work
Produce a self-executing jar and deploy it on a docker image.
7 Introduction to Spring Cloud and microservices architectures
- Distributed architecture and microservices, microservices architecture patterns.
- An overview of Spring Cloud.
- Outsource configuration and version management with Spring Cloud Config.
- Register and dynamically locate services with Spring Cloud Netflix.
- Implement load balancing with Spring Cloud LoadBalancer.
- Create an API Gateway with ZUUL and secure access with Spring Security.
- Last line removed
Hands-on work
Reverse engineering of a monolithic application in a microservices architecture.
