This article explains why a Spring Boot application fails to locate a template file when packaged as a JAR, details the step‑by‑step debugging process, and provides code solutions using ClassPathResource or PathMatchingResourcePatternResolver to correctly read resources inside the JAR.
This article explains how to dynamically load JAR files in a Spring Boot application, covering core concepts, benefits, usage of SpringBootClassLoader, creation of JARs, and alternative third‑party OSGi‑resource‑locator approaches with full code examples.
This guide explains why SpringBoot JAR files become large when bundled with many external libraries, and provides a step‑by‑step method—including Maven configuration changes and runtime loader settings—to shrink the JAR by removing the BOOT‑INF/lib folder while preserving application functionality.
This article explains the concepts and step-by-step implementation of dynamically loading JAR packages in Spring Boot applications, covering built‑in classloader usage, creating JARs, and leveraging third‑party libraries to enhance flexibility and extensibility.
This article explains the differences between JAR and WAR files, why Spring Boot runs with an embedded Tomcat when packaged as a JAR, how deployment changes when using an external Tomcat, and provides step‑by‑step instructions with Maven configurations to build Spring Boot applications as either JAR or WAR packages.
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 guide explains what JAR files are, the typical formats they contain for Java applications, and provides step‑by‑step command‑line commands—including jar and unzip—to list, extract, and examine the contents of JAR archives without modifying the original files.
This article explains why a Spring Boot project runs differently when packaged as a JAR versus a WAR, outlines the historical evolution of Java web containers, compares the characteristics of JAR and WAR files, and provides step‑by‑step Maven commands and pom.xml configurations for building both package types.
This article explains why a Spring Boot application behaves differently when run as a JAR versus deployed as a WAR, outlines the historical context of servlet containers, compares JAR and WAR formats, and provides step‑by‑step Maven commands and pom.xml modifications for packaging both types.
This article explains common Maven commands, describes why a JAR built for execution cannot be imported by a third‑party project, and provides step‑by‑step solutions using the maven‑compiler‑plugin and maven‑assembly‑plugin to create dependency‑inclusive JARs.
This article describes Qunar's end‑to‑end automated workflow for detecting high‑risk Jar component vulnerabilities, collecting asset information, orchestrating remediation with a SOAR platform, and leveraging the TCDEV auto‑upgrade service to reduce manual effort and improve security operations efficiency.
This article explains the structure and purpose of JAR files, the META-INF directory, manifest syntax, name‑value pairs, main and per‑entry attributes, signing mechanisms, verification steps, JAR indexing, service‑provider configuration, Class‑Path handling, and package sealing in Java.
This article provides a comprehensive overview of the JAR file format, detailing the structure and purpose of the META-INF directory, manifest sections, signing files, index files, class‑path attributes, and service provider configuration, while also presenting the formal syntax specifications and examples for each component.
This guide explains step‑by‑step how to decompile a JAR with JD‑GUI, edit the extracted Java source in Eclipse, recompile the class, replace it in the original JAR, and rebuild the package, providing a practical method for updating embedded class files.
