springside/springside4

SpringSide4 is a reference codebase for building Java web applications using Spring Framework. It is intended as a collection of practical examples and best-practice patterns for the Java enterprise ecosystem, showing how to assemble common components in a structured way. The goal is not a blank-slate starting point but a demonstrated, working architecture that developers can study and adapt. The project contains several modules. The Utils module is a Java utility library aiming to balance performance and ease of use, drawing from multiple established open-source Java libraries. The BootApi module is a web service application built on Spring Boot, suitable as a backend for service-oriented architectures or as the server side behind a browser front-end. A third module called Showcase provides additional code examples beyond the core two. All examples are tied to a concrete fictional scenario: a peer-to-peer library where users register books they own and lend them directly to each other, without any central institution or librarian involved. This gives the example code a real application context rather than leaving it as purely abstract scaffolding. To get started, you run a quick-start script in the project root directory. It installs the project modules into a local Maven repository and launches the BootApi application in development mode at localhost port 8080. The README is primarily written in Chinese. Documentation beyond the README lives in the project's GitHub wiki. The README also notes that the original official website domain has expired. A related project from Vipshop (VJTools) is linked at the top as a more recent open-source resource from the same developer community.
