What is shiro-casdoor?

This plugin connects Apache Shiro, a Java security framework, with Casdoor, an open-source authentication platform. In practical terms, it lets your Java application verify user identities using Casdoor's login system, so you don't have to build your own password handling or session management from scratch. When a user logs in through Casdoor, they receive a digital token (specifically a JWT access token). Your application's frontend then sends that token along with each request to your backend. This plugin acts as a checkpoint on the backend that reads the token, validates it with Casdoor, and lets the request through if the user is legitimate. Once authenticated, your application can easily access the user's profile information that was stored inside the token. A developer maintaining a Java web application that already uses Apache Shiro for security would use this when they want to add single sign-on or centralized authentication. For example, if you run an internal suite of company tools and want all employees to log in once through a central Casdoor portal rather than separately for each tool, this plugin handles the verification on the Java side. The README points to an example project for Spring Boot with Shiro to show this in action. The project focuses on a specific integration point rather than being a full security solution. It assumes you already have or will set up Casdoor as your identity provider and Apache Shiro in your Java application. For broader Java integration with Casdoor, the maintainers also point to other libraries like a general Java SDK and a Spring Boot starter, suggesting this particular repo fills a narrow role for teams specifically committed to the Shiro framework.
