An open API service indexing awesome lists of open source software.

Java

Java was originally developed as an alternative to the C/C++ programming languages. It is now mainly used for building web, desktop, mobile, and embedded applications. Java is owned and licensed through Oracle, with free and open source implementations available from Oracle and other vendors.

https://github.com/ivangfr/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.

In this project, we’ll create six apps using Spring Boot, Quarkus, and Micronaut. For each framework, one app will use blocking Web with Tomcat, and the other will use non-blocking Reactive with Netty. We’ll build both JVM and Native Docker images. For Spring Boot, additional images will test configurations with Virtual Threads, CDS, and AOT
