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 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. Additionally, we will use OAuth2 (Social Login) to secure both applications.

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 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.

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

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 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.

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 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 goals of this project are to: 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 for testing applications.

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.

The goal is to explore Axon. We will develop a food-ordering app comprising 3 Spring Boot applications: customer-service, restaurant-service, and food-ordering-service. These services are implemented with CQRS and Event Sourcing, utilizing the Axon Framework. They connect to axon-server, which serves as the Event Store and Message Routing solution.

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

The goal of this project is to study the JPA relationships: one-to-one, one-to-many / many-to-one, and many-to-many.

A Spring Boot 3 RESTful API for managing departments and employees. Features include CRUD operations, Excel/PDF reporting with JasperReport, async email sending with Thymeleaf, Dockerized PostgreSQL, and database migrations with Flyway. Enhanced with Swagger documentation, and tested using JUnit 5, Mockito, and Testcontainers.

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.
