Focus on Java-related technologies: SSM, Spring ecosystem, microservices, MySQL, MyCat, clustering, distributed systems, middleware, Linux, networking, multithreading. Occasionally cover DevOps tools like Jenkins, Nexus, Docker, and ELK. Also share technical insights from time to time, committed to Java full-stack development!
The article analyzes MySQL's dwindling open‑source credibility, mounting security vulnerabilities, performance regressions, and Oracle's commercial lock‑in, contrasting it with MariaDB's transparent development and the growing migration of applications to MariaDB or PostgreSQL for better security and performance.
This article introduces AgentScope, Alibaba's open‑source Java multi‑agent framework, compares its design, advantages, and use cases with Spring AI Alibaba, showcases key features such as ReAct reasoning, built‑in RAG and memory, and provides quick‑start code examples and the project repository.
This article examines why Java is often labeled slow, dispels three major misconceptions about interpretation, garbage‑collection pauses, and startup time, presents concrete benchmark data against other languages, and explains how modern JVM features and framework choices actually shape performance.
JetBrains' IntelliJ IDEA 2026.1 EAP 3 finally moves deleted files to the system recycle bin, adds extensive Spring, Java, Kotlin, AI, and performance improvements, and fixes over 70 known issues, preparing the IDE for remote and distributed development.
This guide walks you through installing Docker, Git, and Node.js on a macOS machine, cloning the OpenClaw repository, configuring the gateway token, installing the Feishu plugin, and verifying that the AI agent can be controlled via Feishu messages, all without relying on cloud services.
This article introduces MyPerf4J, a Java‑agent based, low‑overhead performance monitoring tool that provides real‑time metrics such as RPS, latency percentiles, memory usage and GC statistics, and explains how to install, configure, run and uninstall it in development and production environments.
Upgrading to Spring Boot 4 brings Jackson 3, which reorganizes packages, replaces ObjectMapper with JsonMapper, changes the default date format to ISO‑8601, and converts checked exceptions to RuntimeException, requiring developers to adapt code, adjust configurations, and understand the design rationale to avoid runtime bugs.
This article explains the common reasons Spring transactions become ineffective or fail to roll back—such as wrong method visibility, final modifiers, self‑invocation, non‑Spring beans, multithreading, unsupported table engines, misconfigured propagation, swallowed exceptions, and improper rollback settings—while providing practical code solutions and best‑practice recommendations.
This guide walks you through installing n8n via npx or Docker, registering an account, understanding core concepts like workflows, nodes, and connections, and building a complete AI‑driven automation that fetches Weibo hot topics, processes them with a large language model, and emails the results.
This article explores why many enterprises continue to run on JDK 8 despite newer releases, examining compatibility breaks, stability, learning costs, third‑party library support, performance trade‑offs, commercial considerations, and toolchain readiness, and offers practical guidance for migration decisions.
