JeecgBoot is an enterprise-grade low-code development platform that accelerates application delivery through AI-powered code generation, online form/report builders, and workflow integration. The backend is built on Spring Boot 3 with MyBatis-Plus, Shiro, and JWT, supporting both monolithic and microservice architectures (Spring Cloud, Nacos, Sentinel, XXL-Job). The frontend uses Vue 3 + TypeScript + Ant Design Vue with a rich component library including JVxeTable for editable grids and schema-driven forms. The platform provides comprehensive RBAC, multi-tenancy, dynamic data sources, data dictionaries, and third-party integrations (DingTalk, WeChat, Feishu). A dedicated AI module (airag) offers RAG knowledge bases, LLM chat, voice/image generation, and MCP plugin support. The codebase is actively maintained with frequent commits and a large community, though it contains some commented-out legacy code and hardcoded security values that represent minor technical debt.
DynamicTp is a Java library for dynamic thread pool management, primarily targeting Spring Boot applications. It allows runtime modification of thread pool parameters (core size, max size, queue capacity, etc.) via configuration centers like Nacos, Apollo, Zookeeper, Consul, Etcd, and Polaris. The library provides a rich set of executor variants (eager, ordered, priority, scheduled) and integrates with over a dozen middleware frameworks (Dubbo, gRPC, RocketMQ, RabbitMQ, Tomcat, Jetty, Undertow, Hystrix, Motan, OkHttp3, Thrift, SofaRPC, Tars, LiteFlow, brpc) by wrapping their native thread pools. It includes comprehensive monitoring and alerting: metrics collection via Micrometer, JMX, and logging; notification channels for DingTalk, WeChat, Lark, email, and custom notifiers; and alarm thresholds for capacity, liveness, rejections, and timeouts. The architecture is modular: a core module defines executors, registries, and lifecycle management; a common module provides utilities, parsers, queues, and SPI extension points; adapter modules wrap middleware executors; starter modules provide Spring Boot auto-configuration; and extension modules add optional features like Redis rate limiting and OpenTelemetry tracing. Key entry points are the @EnableDynamicTp annotation, DtpRegistry for executor registration, and ThreadPoolBuilder for programmatic pool creation. External dependencies include Spring Boot, Guava EventBus, ByteBuddy (for interception), Micrometer, and various config-center client libraries.
This is a comprehensive e-commerce backend platform built with Spring Boot 3.5+, JDK 17, and a multi-module Maven architecture. In production, it serves two distinct APIs: `mall-admin` (admin management) and `mall-portal` (customer-facing storefront), plus a dedicated `mall-search` module for Elasticsearch-powered product search. The system handles product cataloging, order lifecycle management, user registration/authentication, coupon and promotion calculations, shopping cart operations, payment integration (Alipay), and content management (home page banners, recommendations). It uses MySQL as the primary database via MyBatis (with generated mappers), Redis for caching and session management, MongoDB for user activity data (browsing history, favorites), RabbitMQ for delayed order cancellation, and MinIO/Aliyun OSS for file storage. Security is implemented with Spring Security and JWT, including dynamic path-based authorization. The codebase follows a layered architecture (Controller → Service → Mapper/DAO) with shared modules `mall-common` and `mall-security` providing reusable utilities for API responses, pagination, exception handling, Redis caching, and authentication. While heavily reliant on MyBatis Generator for data access objects and includes some long service methods, the overall structure is well-organized and modular, making it suitable as a reference for similar e-commerce projects. No data research or analytical components are present; this is purely an application codebase.
This repository is primarily an open-source technical book and architecture knowledge base written in Chinese, rendered as a heavily customized VuePress static site. The core deliverable is the book itself — chapters spanning architecture history, distributed systems foundations, transactions, security, observability, service mesh, containers, and cloud-native infrastructure — rather than a runnable software service. It is best classified as a documentation/application hybrid: the only application code is the VuePress site infrastructure, custom plugins, CI/CD scripts, and an embedded resume slide-deck framework. The repository also links to external companion demo projects (Spring Boot, Spring Cloud, Kubernetes, Istio, serverless) rather than hosting them in-tree.
mini-spring-cloud is an educational, simplified reimplementation of core Spring Cloud components, designed to help developers understand the underlying principles of service registration, discovery, client-side load balancing, declarative HTTP clients (Feign), and API gateway (Zuul). The codebase implements a custom lightweight registry called 'Tutu' and integrates with Netflix Ribbon, OpenFeign, and Netflix Zuul libraries. It follows Spring Cloud Commons abstractions and uses Spring Boot auto-configuration. The project is not intended for production use; it serves as a learning resource with minimal error handling, incomplete feature coverage (e.g., only POST mapping support in Feign contract), and no comprehensive test suite. The architecture is modular with separate Maven modules for each concern, and the code is clean and well-commented in Chinese. However, dependencies are somewhat outdated (Spring Cloud 2021.0.1, Ribbon 2.3.0, Zuul 1.3.1) and the project has not seen recent updates.
This repository is a meta-project for a Spring Cloud microservices demo, now superseded by the Opensabre framework. It contains no actual source code; instead, it aggregates several external submodules (opensabre-framework, base-authorization, base-organization, base-gateway, etc.) via Git submodules. The root pom.xml defines dependencies for Spring Boot 2.1.10, Spring Cloud Greenwich, and Alibaba Cloud 2.1.0, all of which are outdated. The README explicitly states that the project has been replaced by a newer version. As a standalone repository, it provides no reusable code or components; it serves only as a historical reference or a pointer to the submodules. The repository is effectively deprecated and should not be used for new projects.
