A tinkering programmer and author of "Spring Cloud Microservices in Action"
This guide walks you through setting up Ollama for local large‑model serving, creating a Spring Boot project with Spring AI support, writing a unit test to query the model, and explains how to add the necessary dependencies for AI integration in existing Java applications.
Oracle’s release of Java 23 introduces a suite of preview JEPs—including primitive pattern matching, module import declarations, flexible constructors, and new library APIs—while also previewing performance, tooling, and management enhancements, and it hints at upcoming features slated for Java 24.
This article builds a simple Spring Boot Greetings API, configures Maven profiles for Tomcat, Jetty, and Undertow, creates Docker images for each, runs load‑testing benchmarks across multiple concurrency levels, and analyzes startup time, CPU, memory, and response performance to determine the optimal embedded server.
This article traces the evolution of databases from early theoretical research through commercial, open‑source, and cloud eras, highlights China's rapid rise in the field, and explains why databases remain the indispensable foundation of modern software.
Learn how to simplify repetitive error-handling code in Spring Boot by creating a custom @ErrorHandler annotation that leverages Spring AOP to automatically log exceptions, with step-by-step instructions, required dependencies, annotation definition, aspect implementation, and usage examples.
Redis has introduced a multithreaded query engine that dramatically boosts throughput and lowers latency for vector searches, enabling scalable, real‑time retrieval‑augmented generation (RAG) workloads while preserving the low‑latency performance of its core in‑memory database.
This article recounts a developer's journey from a fresh graduate to a senior backend engineer, detailing two real‑world incidents—a pseudo‑memory‑leak in a C++ service and a uint overflow that caused traffic bursts—showing the analysis steps, code fixes, and lessons learned for reliable backend development.
Spring AI has added full support for OpenAI's structured output feature, enabling developers to define JSON schemas for AI responses, with example code showing how to configure prompts, response formats, and BeanOutputConverter for seamless JSON-to-Java bean conversion, plus Spring Boot starter configuration.
The author reflects on reading Mark’s ‘Clean Code’ sequel, sharing how seemingly ‘old‑school’ heuristics—like backup configs, commit‑message discipline, and the rubber‑duck method—remain vital in modern software development, despite flashy tools, and urges readers to embrace practical, experience‑driven practices.
IntelliJ IDEA 2024.2 introduces a suite of developer‑focused enhancements—including instant Spring Data JPA queries, cron expression auto‑completion, GraalJS‑powered HTTP client, advanced log management, real‑time performance charts, and rich data‑format visualizers—designed to boost productivity for Java and Kotlin programmers.
