Top Architect focuses on sharing practical architecture knowledge, covering enterprise, system, website, large‑scale distributed, and high‑availability architectures, plus architecture adjustments using internet technologies. We welcome idea‑driven, sharing‑oriented architects to exchange and learn together.
Discover how to set up MySQL InnoDB ReplicaSet and configure MySQL Router 8.2 for automatic read/write splitting, enabling reads to be routed to replicas and writes to the primary without code changes, complete with step-by-step commands, configuration snippets, and visual verification.
This article introduces Hutool, a comprehensive Java utility library, outlines its main modules such as SecureUtil, HtmlUtil, and CronUtil, provides code snippets for common tasks like password hashing, HTML escaping, and scheduling, and shares practical tips for integrating these tools into applications.
A newcomer replaced MyBatis with MyBatis‑Plus in an old MySQL‑based project, encountered a "Conversion not supported for type java.time.LocalDateTime" error, traced it to MyBatis 3.5.1 dropping built‑in type handling and an outdated mysql‑connector‑java driver, and resolved it by upgrading the driver while also fixing a related validation bug that caused production failures.
A senior architect recounts twelve common coding habits—like over‑splitting services, endless method length, deep nesting, misleading comments, and missing logs—that dramatically reduce code readability and increase maintenance difficulty, illustrating each with vivid examples from a fictional developer.
This article explains how to redesign Spring MVC controllers by extracting common responsibilities, defining a standard response wrapper, using ResponseBodyAdvice for automatic packaging, handling String return types, and implementing comprehensive validation and custom exception handling to produce clean, maintainable backend code.
A senior architect recounts a code review where a colleague wrapped a simple two‑payment‑method order system in strategy, factory, and abstract‑factory patterns, then explains why such over‑design hurts maintainability, when to apply complex patterns, and practical guidelines for clean backend architecture.
This guide explains three ways to automatically cancel orders that remain unpaid for 30 minutes in a Spring Boot application, covering scheduled tasks, RabbitMQ delayed queues, and Redis key‑expiration events, with complete code examples and configuration details.
This guide introduces RedisInsight, outlines its key features, provides step‑by‑step Linux installation, environment‑variable configuration, service startup, Kubernetes deployment instructions, and demonstrates basic UI usage for monitoring, CLI interaction, and memory analysis of Redis instances.
This article explains how to design a high‑concurrency ticket‑snatching service that can handle millions of requests by combining multi‑layer load balancing, weighted Nginx round‑robin, in‑memory stock with Redis‑backed global inventory, and Go’s native concurrency, complete with code samples and performance results.
AI can quickly generate functional code, but turning that 80‑point prototype into a reliable, secure, production‑ready product requires human engineers to perform rigorous validation, refactoring, and polishing—roles the author dubs ‘post‑processing engineers’—who bridge AI’s speed with real‑world robustness and profitability.
