Dedicated to sharing advanced Java technical insights, daily work snippets, and the power of persistent effort.
The article explains that SpringBoot’s request capacity is governed by Tomcat’s thread pool and connection settings, derives the formula max‑connections + accept‑count, demonstrates it with a small‑scale experiment, and discusses related concurrency pitfalls in singleton beans.
This article walks through a Spring Boot solution for dynamically masking sensitive user data—such as names, ID numbers, phone numbers, and custom fields—by defining custom annotations, a configurable rule engine, a Redis‑backed context holder, and a Jackson serializer that applies masking at JSON serialization time, all while keeping performance overhead low.
The article walks through a performance test of inserting over 100,000 rows with many columns, showing how a naïve loop takes about 80 seconds while JDBC batch, manual transaction control, and MyBatis/MyBatis‑Plus batch APIs can reduce the time to roughly one second.
This article explains how Spring Event provides a publish‑subscribe mechanism to decouple Spring components, details its default synchronous behavior, shows how to make listeners asynchronous, demonstrates ordering and error handling, compares it with message‑queue solutions, and offers practical guidelines for safe usage.
This article explains Vue.js template syntax, covering how interpolation with double curly braces inserts data, the role of directives like v-bind, v-model, and v-on, shorthand notations, event modifiers, and the use of dynamic arguments introduced in Vue 2.6.0, all illustrated with concrete code examples.
This article introduces Vue as a progressive JavaScript framework, explains its core features such as reactive data binding, component‑based development, and virtual DOM, and walks through installation methods, a simple counter example, and a brief comparison with React and Angular.
This article provides a comprehensive overview of the Java Collections Framework, explains frequent mistakes such as modifying collections during iteration or using toMap with null values, and introduces practical utility libraries like Hutool, Apache Commons Collections, and Guava to help developers write safer and more efficient code.
Redis processes core command operations in a single thread but incorporates multithreaded components for asynchronous tasks and network I/O, using an event‑driven epoll model and optional I/O threads introduced in v6.0 to boost performance on multi‑core systems.
The article provides a detailed technical comparison of MyBatis-Flex with MyBatis-Plus and Fluent-MyBatis, covering feature matrices, code examples for basic queries, aggregation, complex conditions, multi‑table joins, partial updates, and a step‑by‑step Spring Boot integration guide, before concluding on its maturity and suitability for production.
This guide explains how to protect a Spring Boot application from reverse engineering by configuring ProGuard to obfuscate compiled class files, adding the necessary Maven plugin settings, and verifying the resulting obfuscated JAR.
