This article explains why and how to run Windows environments in Docker containers, compares the two container modes, lists supported Windows images, provides a quick Hello World example, and highlights the main limitations you should consider before adopting Windows containers.
This article demystifies authentication concepts—Cookie, Session, Token, JWT, and OAuth2—using clear analogies, explains their inner workings, advantages, drawbacks, and provides practical guidance on when to choose each mechanism for modern web applications.
This article compiles essential Spring and Java utility methods—including assertion checks, object and collection handling, file I/O, resource management, and reflection/AOP tools—providing concise code examples and usage guidelines to help developers avoid redundant code and write cleaner, more reliable applications.
The article explains why process orchestration is crucial for backend systems, illustrates common pitfalls of scattered if‑else logic, and demonstrates how a flow engine combined with plugin extensions—using the open‑source MemberClub project—provides clean, extensible business logic execution.
Spring Boot’s “convention over configuration” hides many default settings that can cause performance bottlenecks and runtime failures, from Tomcat and HikariCP connection limits to JPA lazy loading, timezone serialization, logging, caching, file upload limits, thread pools, and transaction timeouts, and the article shows how to tune each.
This guide introduces the open‑source Jianmu CI/CD tool, explains its no‑code/low‑code approach, provides step‑by‑step deployment instructions via Docker‑Compose or Kubernetes, and walks you through creating and running a sample workflow, with links to online demos and resources.
The article reviews Java technologies that have become outdated—such as JSP, Struts, Hibernate, Applet, Swing, JDBC, and XML—explaining why they no longer merit learning and recommending modern alternatives like Spring MVC, MyBatis, and a deep understanding of Servlets for today's backend development.
This article explains MyBatis streaming queries, introduces the Cursor interface and its methods, demonstrates common pitfalls, and provides three practical solutions—using SqlSessionFactory, TransactionTemplate, or @Transactional—to keep database connections open while processing large result sets efficiently.
This article explains MyBatis streaming queries using the Cursor interface, demonstrates common pitfalls such as closed connections, and provides three practical solutions—including SqlSessionFactory, TransactionTemplate, and @Transactional—to reliably process large result sets with minimal memory usage.
This article examines why containerizing MySQL often leads to data‑security, performance, state, and resource‑isolation problems, outlines five key drawbacks of running MySQL in Docker, and explains the scenarios where containerization can still be viable.
