    Spring Cloud Examples

    Spring Cloud Examples

    Spring Cloud learning cases, service discovery, service governance

    The Spring Cloud Examples repository appears to be a collection of sample applications and demos that illustrate how to use Spring Cloud and related cloud-native patterns in real-world microservice or distributed-service contexts. It provides working codebases showing how to wire together service discovery, configuration, inter-service communication, and possibly resilience patterns — giving developers a hands-on playground rather than theoretical documentation. By studying the examples, one can understand how Spring Cloud works in practice: how to structure services, how to configure them, and how they interact under realistic conditions. ...

    Design and implementation of flash sale system

    Miaosha is a high-concurrency “flash sale” (秒杀) demo that explores how to design a backend capable of withstanding extreme, bursty traffic during limited-time events. It illustrates patterns like cache-first reads for hot data, request rate limiting, and asynchronous order processing to protect databases under load. The project demonstrates stock deduction strategies designed to avoid overselling, combining pre-decrement in cache with reliable persistence and message-driven confirmation. Security hardening is addressed with ideas such as dynamic request paths, anti-bot measures, and one-time tokens to reduce automated abuse. ...

    Firing Range

    Firing Range is a test bed for web application security scanners

    Firing Range is an intentionally vulnerable web application designed to evaluate the real-world effectiveness of web security scanners and training exercises. Deployed as a cloud-friendly app, it aggregates dozens of vulnerability patterns in repeatable, labeled routes so tools can be benchmarked on coverage and noise. The project doesn’t just include simple XSS forms; it spans variants such as DOM-based issues, context-sensitive sinks, template mishandling, CSRF, open redirects, and mixed content problems. Each scenario is crafted to reflect how bugs appear in production—behind frameworks, in odd encodings, or across redirects—so scanners must demonstrate accurate crawling and context understanding. ...
