json-io, a decade‑old Java JSON library known for zero‑config, circular‑reference support, and lightweight size, has added full TOON (Token‑Oriented Object Notation) read/write capabilities, a token‑efficient format designed for LLMs that can cut serialization costs by 30‑60% and integrates seamlessly with Spring Boot and Spring AI.
This guide explains how to integrate Claude Code (or Codex) into JetBrains IDEA using the Agent Client Protocol (ACP), covering plugin installation, JSON configuration, adapter setup, MCP enabling, and the benefits of a unified AI‑coding workflow.
This article explains how Claude Code, a super‑intelligent AI agent, differs from traditional code‑completion tools, introduces its official SDK limitations, and provides a comprehensive guide to the community‑driven Claude Agent SDK for Java—including one‑shot, blocking, and reactive APIs and a practical RAG‑based Q&A example.
Developers often waste time manually editing /etc/hosts when switching between local, test, and production environments, and existing GUI tools like SwitchHosts are bulky and lack CLI support; this article explains the problem, the design of a lightweight Rust‑Tauri solution called Hostly, and its key features.
The article critiques the hype around unified Java data‑access libraries like dbVisitor, compares them with purpose‑built ORM Jimmer, and argues that in the AI era lightweight tools such as Spring Boot's JdbcClient may replace traditional ORMs altogether.
A detailed benchmark shows that enabling Java virtual threads in Spring Boot 4.0 makes Tomcat handle up to fifteen times more requests than Jetty, while startup times remain similar, and the article explains the test setup, configuration steps, native image builds, and the reasons behind Jetty's limitation.
The 2025 release of mica-mqtt introduces 19 versions with major architecture refactoring, performance boosts via mica-net integration, multi‑protocol support, AI (MCP) capabilities, extensive plugin enhancements for Solon and Spring, and a roadmap for 2026 improvements, all documented with code snippets and repository links.
Spring Authorization Server has been integrated into Spring Security 7.0, ending its independent lifecycle; the article explains the three historical eras, the reasons for the merge, and provides concrete dependency and configuration changes—including Lambda DSL updates—to help developers migrate from SpringBoot3 to SpringBoot4 with minimal effort.
This article explains how Spring Boot 4.0’s @EnableMultiFactorAuthentication annotation simplifies the implementation of password‑plus‑one‑time‑token multi‑factor authentication, providing step‑by‑step code examples, custom token services, endpoint‑level MFA configuration, and production‑grade considerations.
Upgrading to Spring Boot 4 can cause missing @WebMvcTest, MockMvc, and other compilation errors because the framework modularizes its large autoconfigure JAR into many smaller starters, requiring updated dependencies and configuration changes to restore test execution and improve startup performance.
