Basic introduction

Struts2 is a Web application framework based on the MVC design pattern. It is essentially equivalent to a servlet. In the MVC design pattern, Struts2 acts as a controller to establish data interaction between the model and the view. Struts 2 is the next generation product of Struts. It is a new Struts 2 framework that merges the technologies of Struts 1 and WebWork. Its new Struts 2 architecture is very different from the Struts 1 architecture. Struts 2 takes WebWork as the core and uses an interceptor mechanism to process user requests. This design also enables the business logic controller to be completely separated from the ServletAPI, so Struts 2 can be understood as an updated product of WebWork. Although there are big changes from Struts 1 to Struts 2, compared to WebWork, the changes in Struts 2 are very small.
