Its capability surface covers the construction of JSON-based web endpoints, server-side logic for the JVM, and the implementation of scalable web architectures.

Spark is a lightweight Java web framework and embedded server designed for building web applications with minimal boilerplate. It functions as an HTTP routing engine that maps URL paths and methods to handler functions, providing a specialized domain specific language for web development in Kotlin. The framework enables the implementation of REST APIs and web services through the definition of HTTP routes. It supports the extraction of dynamic path parameters and the transformation of response data into formats such as JSON. Additional capabilities include the ability to serve static files a

Spring PetClinic is a reference application for the Spring Framework, serving as a complete implementation that demonstrates the architecture and best practices for building Java services. It functions as a veterinary practice management system designed to track pet owners, animal records, and clinical visit histories. The project provides a practical example of a containerized web application, illustrating how to integrate a Java application with relational databases like MySQL and PostgreSQL. It serves as a guide for learning how to develop an application using the model-view-controller pat

Dropwizard is a Java web application stack and REST framework used to build production-ready web services. It integrates an embedded HTTP server with operational tools to provide a complete environment for developing network interfaces that exchange JSON data. The project provides a set of core technology stacks for relational data mapping, schema migration, and operational performance monitoring. It includes a relational database migration tool to track schema updates and execute versioned scripts before an application starts. The framework covers a broad capability surface including reques

Javalin is a lightweight web framework for Java and Kotlin designed for building REST APIs and web applications. It functions as an embedded Jetty web server, allowing applications to run as standalone processes without the need for an external servlet container. The project provides specialized frameworks for diverse communication patterns, including a REST API framework with automatic OpenAPI schema generation, a GraphQL API framework with query and mutation resolvers, and a WebSocket server for bidirectional real-time communication. It also includes a dedicated framework for pushing real-t

GeoServer 是一个开源地理空间数据管理器和发布者，使用开放标准共享、编辑和处理地理信息。它作为 OGC 地理空间服务器和 Web 地图服务提供商运行，通过标准化的 Web 协议向客户端应用交付空间数据和计算测量结果。 该平台支持将各种文件格式的地理空间数据集发布到 Web 服务，并支持通过中央服务器修改和管理空间数据集。它提供了远程空间处理功能，以及使用发现服务为可用空间数据集创建可搜索目录的功能。

This is an open-source video player application for Android that compiles native C and C++ libraries using the Android NDK and CMake. The build system automatically discovers the Android SDK from environment variables and selects the appropriate Java runtime (8, 11, or 17) for different build tools, while allowing control over which CPU architectures (ARM, x86) to target. The application manages media libraries by scanning local storage and fetching metadata from external services to organize video files with cover art, descriptions, and series grouping. It streams video from both local devic

This repository is a collection of Java backend projects, encompassing a web application suite, a real-time chat server, a web crawler, and an authentication system.
