Knife4j is a set of Swagger2 and OpenAPI3 All-in-one enhancement solution

Library for OpenAPI 3 with spring-boot

The goal of this project is to secure movies-app using Keycloak (with PKCE). movies-app consists of two applications: one is a Spring Boot Rest API called movies-api and another is a React application called movies-ui.

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.

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.

The goal of this project is to implement a "News" processing pipeline composed of five Spring Boot applications: producer-api, categorizer-service, collector-service, publisher-api and news-client.

Experiment with Kafka, Debezium, and ksqlDB. research-service: Performs MySQL record manipulation. Source Connectors: Monitor MySQL changes, push messages to Kafka. Sink Connectors and kafka-research-consumer: Listen to Kafka, insert/update Elasticsearch. ksqlDB-Server: Listens to Kafka, performs joins, and pushes new messages to new Kafka topics.

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.

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.

A highly opinionated and complete template for Spring Boot projects ready for production

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.

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 Boot and Swagger 3 example - configuration for API description / response example - Swagger annotations with OpenAPI 3

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.

The goal of this project is to explore GraphQL. For it, we will implement two microservices: author-book-api and book-review-api.

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.

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.

Goals: Implement an Ethereum Smart Contract called SoccerManager and deploy it to Ethereum Blockchain running locally; Implement 2 Spring Boot BE applications, ethereum-api and player-api, that uses Web3j to communicate with Ethereum blockchain; Implement 2 React FE applications, ethereum-ui and player-ui, that communicate to their respective BE.

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
