- Reactive repositories for non-blocking data access.
- Writing custom queries: derived queries, @Query annotation.
- Transaction management.
- Exposing repositories with Spring Data REST, presentation of HATEOAS.
Hands-on work
Writing a data access layer with Spring Data JPA, exposing repositories in REST HATEOAS with Spring Data Rest.
3 How to secure your application with Spring Security
- Definition of a user repository.
- Authentication modes: basic, form-based, bearer token.
- Using JWT: defining claims, signing and verifying with an asymmetric key system.
- The OpenID Connect specification, the coupling between Spring Security and an OpenID Connect server (Keycloak).
- Securing routes, methods and views.
- Protection against CSRF attacks.
- Security configuration for a reactive web application.
Hands-on work
Securing a Spring MVC REST API with an OpenID Connect server and JWT, securing a Spring MVC GUI.
4 Batch processing with Spring Batch
- Job definition: parallel, conditional or sequential step execution.
- The different types of step: tasklet step, chunk oriented step.
- ItemReader, ItemProcessor and ItemWriter interfaces.
- Retry strategies.
- Job execution and supervision: startup, shutdown, incident recovery, access to statistics.

All the subjects mentioned in the title were covered in the course, with even a few digressions to find out more about the uses and implementation of certain points to consolidate learning.

Interesting course but difficult to follow. The instructor discovered Spring 4 during the course and spent too much time testing "if we change this/that". The pace was too fast, with no time to assimilate the steps. A more demonstrative approach would have helped. The trainer sometimes went too far into non-essential details, which made it more difficult to understand. For the exo's, it would have been good to have a simpler environment.
