This article introduces a Java utility class named CompressUtil that provides methods for compressing files and directories into ZIP archives, handling duplicate filenames, creating new files safely, and offering HTTP endpoints for downloading the generated ZIP files in a single request.
This article introduces Spring Boot 3's filter mechanism, outlines core functions and application scenarios, and provides detailed code examples for eight built‑in filters such as CharacterEncodingFilter, CorsFilter, and HiddenHttpMethodFilter, helping developers build secure and efficient web applications.
This article reviews common Java backend technologies, explains why JSP, Struts, Hibernate and several legacy tools are no longer worth learning, and highlights the essential concepts—especially deep mastery of Servlets—that modern Java developers should focus on in 2024.
The article reviews several Java backend technologies—JSP, Struts, Hibernate, Servlet, Applet, Swing, JDBC, and XML—explaining why they are now considered obsolete or low‑priority and recommending modern alternatives such as Spring MVC, MyBatis, and deep Servlet knowledge for current development.
Based on 20 years of Java experience, this article evaluates Java technologies like JSP, Struts, Hibernate, and Servlet against practical use, depth of understanding, and interview relevance, recommending which to drop, which to master, and highlighting alternatives such as Spring MVC and MyBatis.
The article reviews a Java veteran's 20‑year experience to identify backend technologies such as JSP, Struts, Hibernate, Servlet, Applet, Swing, JDBC and XML that are now outdated or less essential, and recommends focusing on Spring MVC, MyBatis and a deep understanding of Servlets for modern development.
Apache Tomcat is the underlying servlet container and web server that Spring Boot automatically embeds via the spring‑boot‑starter‑web dependency, but junior developers often miss its core roles—managing servlet lifecycles, serving static resources, and compiling JSPs—so learning Tomcat (or swapping it for Jetty by adjusting Maven exclusions) clarifies what Spring Boot abstracts and enables flexible container choices.
This article reviews outdated Java technologies—JSP, Struts, Hibernate, and others—explaining why they are no longer essential for modern backend development and offering clear guidance on which skills to prioritize or abandon.
This article explains how to use IntelliJ IDEA's diagram feature to view, clean up, and explore the inheritance and interface implementation relationships of Java Servlet classes, including tips for removing irrelevant nodes, inspecting class members, adjusting visibility, zooming, and adding related classes to the diagram.
This guide explains how to use IntelliJ IDEA’s diagram feature to view, clean up, and explore inheritance and interface relationships of Java classes such as Servlets, including removing unwanted nodes, inspecting members, adjusting visibility, zooming, adding classes, and jumping to source code.
The article examines which Java backend technologies are considered obsolete—such as JSP, Struts, Hibernate, and others—by applying criteria like practical usage, depth of understanding, and interview relevance, and advises learners on what to drop, prioritize, or master for modern development.
This tutorial explains how to use IntelliJ IDEA's diagram feature to view, clean up, and explore the inheritance and interface implementation relationships of Java Servlet classes, including removing irrelevant nodes, inspecting class members, adding other classes, and jumping to source code.
This guide explains how Spring Boot automatically registers Servlet, Filter, and Listener beans, how to customize their mappings with registration beans, configure the embedded servlet container, and handle JSP limitations, providing code examples and practical tips for backend developers.
The article advises Java developers to abandon learning outdated technologies such as JSP, Struts, and Hibernate, while emphasizing the continued importance of mastering Servlets and recommending a shift to modern frameworks like Spring MVC and MyBatis for effective backend development.
This article explains why Spring Cloud Gateway originally required Netty and could not run in traditional Servlet containers, introduces the new MVC Servlet support added in Spring Cloud 2023 (Gateway 4.1), and provides step‑by‑step instructions for configuring dependencies, routing rules, and custom filters using Tomcat or other servlet containers.
This article reviews common Java technologies—JSP, Struts, Hibernate, Servlet, and others—evaluating their relevance for modern backend development based on practical usage, depth of understanding, and interview value, and offers clear recommendations on what to study or drop.
This article reviews several Java backend technologies—JSP, Struts, Hibernate, Servlet, and others—explaining why they are considered outdated or unnecessary for modern development and offering guidance on what newcomers should focus on instead.
This article explains the differences between JAR and WAR packaging for Spring Boot applications, shows why embedded Tomcat behaves differently from external Tomcat, and provides step‑by‑step instructions with Maven commands and pom.xml modifications to build both JAR and WAR artifacts.
This tutorial walks through building a Spring MVC environment from scratch with Spring 5.3.26, covering traditional XML configuration, servlet registration via web.xml, annotations, and SPI, and shows how to configure a REST controller and required message converters.
This article reviews several Java technologies that have become obsolete or less relevant—such as JSP, Struts, Hibernate, Applet, Swing, JDBC, and XML—explaining why newcomers can safely ignore them and focus on modern alternatives like Spring MVC, MyBatis, and deep Servlet knowledge.
