This tutorial demonstrates how to replace the traditional jar‑upload workflow with an IDEA‑integrated Docker solution, covering environment setup, SSH configuration, Docker daemon connection, SpringBoot code, Dockerfile creation, remote deployment settings, firewall opening, and common troubleshooting steps.
This article introduces the most useful JDK 17 language enhancements—including text blocks, improved NullPointerException messages, records, switch expressions, private interface methods, pattern matching, collection factory methods, new String APIs, Stream API extensions, the modern HttpClient, JShell, direct java file execution, and the Z Garbage Collector—providing code examples and practical guidance for Java developers.
This article details a three‑month, multi‑step migration of a large Android monorepo from AGP 7.2.2 to 8.2.2, covering Transform API deprecation, namespace handling, Gradle and JDK upgrades, build‑feature toggles, third‑party library adaptations, performance optimizations, and the troubleshooting of numerous compilation pitfalls.
This article explains how moving to JDK 17 and the low‑latency ZGC garbage collector can reduce pause times to under 10 ms, improve throughput, and meet demanding real‑time service requirements, while providing practical upgrade steps, JVM tuning parameters, and performance comparisons.
This article explains why upgrading to JDK 17 and switching to the low‑latency ZGC garbage collector can dramatically reduce pause times and improve throughput, compares GC and CPU metrics against G1, and provides step‑by‑step installation and JVM tuning instructions with code examples.
This article outlines JDK 17’s long‑term support status, modular system enhancements, garbage‑collector improvements, sealed classes, pattern‑matching for instanceof and switch, plus developer‑tool upgrades, helping Java developers decide whether to migrate to the latest LTS release.
This article documents the step‑by‑step migration of a Java campus‑blog project from JDK 8 + Spring Boot 2.6 to JDK 17 and Spring Boot 3.2, explaining why the upgrade is worthwhile, detailing code and configuration changes, and sharing solutions to the numerous compatibility issues encountered.
This article explains why upgrading from JDK8 or JDK11 to the long‑term support JDK17 brings significant garbage‑collector performance improvements, new language features, and better framework compatibility, and provides detailed migration steps, Maven and SpringBoot configuration changes, and troubleshooting tips.
This article details the motivation, steps, encountered challenges, and measurable performance gains of upgrading a high‑traffic search recommendation service from JDK 8 to JDK 17, highlighting new Java syntax, modern GC algorithms, deployment procedures, and the resulting reductions in latency, GC pause times, and heap usage.
This article investigates the severe memory growth and latency spikes observed when synchronizing data across data centers in a Netty‑driven online computation service, analyzes the impact of JDK 17 ZGC and direct‑buffer allocation, and presents the debugging steps, source‑code insights, and configuration changes that ultimately resolved the issue.
Didi upgraded its self‑developed Elasticsearch from JDK 11/G1 to JDK 17, adopting ZGC for latency‑critical clusters and tuned G1 for throughput, which eliminated long GC pauses, reduced query latency by up to 96%, cut CPU usage, and dramatically improved stability across multiple production clusters.
This article explains why Java applications should migrate from JDK 8 to JDK 17, introduces GraalVM native‑image technology, provides detailed upgrade procedures, Maven configuration, code examples, and a summary of performance benefits and typical issues encountered during the migration.
