Struts2 is a Java web framework that uses the model-view-controller pattern and consists of 3 core components: Actions, Results, and Interceptors. Actions handle user requests, Results define page transitions, and Interceptors provide extensibility through filters. The document discusses the components and plugins of Struts2, provides examples, and notes pros like extensibility and cons like confusing programming models.
