Springを用いた社内ライブラリ開発
The document describes how to configure Spring MVC to resolve method arguments from the HTTP session. It defines a SessionAttributeArgumentResolver class that implements HandlerMethodArgumentResolver to retrieve attributes from the session based on a key. It also shows how to register the resolver with the WebMvcConfigurer to make it available to controller methods. Finally, it provides an example of how to configure method security in Spring using annotations or Java configuration.
