This article explains why locks are essential in programming, categorizes various lock types such as pessimistic, optimistic, spin, fair, reentrant, and distributed locks, and shows how to choose and implement them in Java for high‑concurrency, high‑availability, and high‑performance systems.
This article explains why Redis needs high availability, defines common failure scenarios, compares several HA solutions, and walks through four deployment patterns—culminating in a three‑Sentinel architecture with a virtual IP to provide seamless, fault‑tolerant Redis access.
This article explains the fundamentals of hash functions, outlines the key characteristics of a good hash algorithm, and dives deep into consistent hashing—its background, mechanism, desirable properties, fault tolerance, scalability, and the use of virtual nodes to solve data skew in distributed systems.
This tutorial explains how to extend Spring Security's OAuth2 authorization server by implementing a custom SMS‑code grant type, covering the necessary configuration classes, bean definitions, token store setup, and client usage examples.
This article provides a complete walkthrough of Nginx, covering its roles as a reverse proxy, load balancer, static file server, and forward proxy, along with detailed configuration examples for global settings, HTTP blocks, server blocks, location directives, upstream modules, and stream handling.
This article walks through preparing a four‑node MySQL environment, configuring password‑less SSH, setting up master‑slave replication with GTID, installing and configuring MHA, testing connectivity, running the manager, verifying automatic failover, and highlighting the key advantages of using MHA for high availability.
This article explains the fundamentals of OAuth2, its four grant types and roles, and provides step‑by‑step Spring Boot and Spring Cloud configurations—including authorization and resource server setup, custom token filters, and Zuul gateway integration—to secure microservice APIs.
This article explains Java's throw‑catch mechanism, the three core principles of exception handling, and demonstrates how to design a custom exception hierarchy and a Spring Boot @ControllerAdvice‑based global handler to simplify error processing and improve code maintainability.
This article explains how to use Maven parent POMs, properties, and BOM (Bill of Materials) to centrally manage version numbers across multi‑module Java projects, resolve dependency conflicts, and simplify builds for backend development teams.
