Keycloak-Clustered extends quay.io/keycloak/keycloak official Keycloak Docker image by adding JDBC_PING discovery protocol.
springboot-keycloak-openldap
The goal of this project is to create a simple Spring Boot REST API, called simple-service, and secure it with Keycloak. Furthermore, the API users will be loaded into Keycloak from OpenLDAP server.
springboot-react-social-login
The goal of this project is to implement an application called movie-app to manage movies. For it, we will implement a back-end Spring Boot application called movie-api and a font-end React application called movie-ui. Besides, we will use OAuth2 (Social Login) to secure both applications.
springboot-react-jwt-token
The goal of this project is to implement an application called order-app to manage orders. For it, we will implement a back-end Spring Boot application called order-api and a font-end React application called order-ui. Besides, we will use JWT Authentication to secure both applications.
springboot-kafka-connect-jdbc-streams
Project goal: Explore Kafka, Kafka Connect, and Kafka Streams. Components: store-api: Inserts/updates MySQL records. Source Connectors: Monitor MySQL changes, push messages to Kafka. Sink Connectors: Listen to Kafka, insert/update Elasticsearch docs. store-streams: Listens to Kafka, processes with Kafka Streams, pushes new messages to Kafka.
springboot-react-basic-auth
The goal of this project is to implement an application called book-app to manage books. For it, we will implement a back-end Spring Boot application called book-api and a font-end React application called book-ui. Besides, we will use Basic Authentication to secure both applications.
springboot-kafka-websocket
The goal of this project is to implement two Spring Boot applications: bitcoin-api and bitcoin-client. The bitcoin-api application simulates BTC price changes, while the bitcoin-client application listens to these changes and updates a real-time UI. The bitcoin-client UI is secured using Basic Authentication.
springboot-keycloak-mongodb-testcontainers
The goals of this project are: 1) Create a Spring Boot application that manages books, called book-service; 2) Use Keycloak as OpenID Connect Provider; 3) Test using Testcontainers; 4) Explore the utilities and annotations that Spring Boot provides when testing applications.
springboot-ldap-testcontainers
The goal of this project is to create a simple Spring Boot REST API, named 'simple-service,' and secure it using the Spring Security LDAP module. Additionally, Testcontainers will be utilized for integration testing.
spring-cloud-stream-event-sourcing-testcontainers
Goal: create a Spring Boot application that handles users using Event Sourcing. So, whenever a user is created, updated, or deleted, an event informing this change is sent to Kafka. Also, we will implement another application that listens to those events and saves them in Cassandra. Finally, we will use Testcontainers for end-to-end testing.
spring-webflux-reactive-databases
The goal of this project is to play with Spring WebFlux on client and server side. For it, we will implement some Spring Boot Java Web applications, product-api, customer-api, order-api and client-shell, and use reactive NoSQL database like Cassandra, MongoDB, Postgres and MySQL.
springboot-kong-keycloak
Goal: create a Spring Boot app called book-service accessible only through the Kong API gateway. In Kong, the kong-oidc plugin will be installed, enabling communication between Kong and Keycloak. This setup ensures that when Kong receives a request for book-service, it validates the request in conjunction with Keycloak to ensure its authenticity.
springboot-rsocket-webflux-aop
The goal of this project is to play with RSocket protocol. For it, we will implement three Spring Boot Java applications, movie-server, movie-client-shell and movie-client-ui. As storage, it's used the reactive NoSQL database MongoDB. All the streaming of movie events and the logging are handling by AOP (Aspect Oriented Programming).
socketio-express-phaser3
The goal of this project is to implement a multiplayer game using Socket.IO, Express and Phaser 3.
spring-kafka-de-serialization-types
The goal is to play with Spring Kafka. We've implemented 5 examples of producer and consumer services that exchanges messages through Kafka using different types of serialization and approaches.
spring-data-jpa-relationships
The goal of this project is to study the JPA relationships: one-to-one, one-to-many / many-to-one, and many-to-many.
springboot-kong-plugins
The goal of this project is to create a simple Spring Boot REST API and securing it with Kong using the LDAP Authentication and Basic Authentication plugins. Besides, we will explore more plugins that Kong offers like: Rate Limiting and Prometheus plugins.
springboot-elasticsearch-thymeleaf
The goal of this project is to implement an application called product-app. It consists of two Spring Boot services: product-api (backend) and product-ui (frontend). Data will be stored in Elasticsearch
spring-cloud-stream-event-routing-cloudevents
The goal of this project is to play with Spring Cloud Stream Event Routing and CloudEvents. For it, we will implement a producer and consumer of news & alert events.
springboot-aws-localstack-dynamodb-lambda-sns-sqs
In this project, we are going to use LocalStack to simulate locally, some services provided by AWS Cloud such as: DynamoDB, Lambda, SNS and SQS. Also, in order to simplify the use of AWS managed services, we are going to use Spring Cloud AWS.
springboot-jpa-studies
The goal of this project is to study JPA Batch Processing (i.e, insert / update / delete a set of records in a single command), JPA Locking and Datetime in JPA.
spring-cloud-stream-kafka-multi-topics
The goal of this project is to create two applications: one as a Spring Boot producer and the other as a Spring Boot consumer. We'll be using Spring for Apache Kafka and Spring Cloud Stream.
springboot-aws-localstack-opensearch-s3-secretsmanager
In this project, we are going to use LocalStack to simulate locally, some services provided by AWS Cloud such as OpenSearch, S3, and Secrets Manager. Also, in order to simplify the use of AWS managed services, we are going to use Spring Cloud AWS.
springboot-caching-neo4j
The goal of this project is to explore how caching works. To achieve this, we will implement a simple Spring Boot application called "restaurant-api." We will use Neo4j for storage and select one of the following solutions (Simple, Caffeine, or Redis) for caching.
spring-integration-examples
The goal of this project is to learn String Integration Framework For it, we will implement some Spring Boot applications and try to use the well known Enterprise Integration Patterns.
springboot-activemq-rabbitmq-delayed-messages
The goal of this project is to create an application that produces and consumes delayed messages randomly. Those messages are sent to ActiveMQ or RabbitMQ. The delayed broker to which the message is sent depends on a feature toggle defined in Unleash.

On this website, I have compiled my Proof-of-Concepts (PoCs) and articles. You can easily search for the technology you are interested in by using the filter. Who knows, perhaps I have already implemented a PoC or written an article about what you are looking for.
spring-boot-nginx-keycloak-cluster
The goal of this project is to use Nginx as a reverse proxy and load balancer for a Keycloak cluster with two instances and a Spring Boot application, called simple-service, also with two instances. The simple-service app will use Keycloak for IAM.
