Spring Boot with Redis in Action

Example of object caching in Redis for Spring Boot applications

Overview

The application is designed as an internal microservice with no public access to it and no user interface.

Data is passed to the service via a POST request. The data can then be read via a GET request. In the current version, the service does not provide a method to remove data from Redis - this is the intention.

It is also expected that the data must be signed. In our simplified case, the signature is a string in the format “key: value”, for example, you can use “login:password” or anything you choose.

Technologies

• Java - version 21

• Spring Boot - version 3.4.3
• Spring Cloud - version 2023.0.3
• Spring Boot Actuator - it's for real-world applications
• Docker - containerization
• Docker-Compose - infrastructure
