Explaining the Difference between Struts 1 and Struts 2 Frameworks

When comparing Struts 1 and Struts 2 frameworks, the main difference lies in their architecture and functionalities. Struts 1 follows a Model 1 architecture, where the business logic and presentation are handled in a single servlet, leading to a lack of clear separation of concerns. On the other hand, Struts 2 utilizes a more modern Model 2 architecture, implementing the MVC (Model-View-Controller) design pattern, which allows for better organization and maintenance of code.

The key difference between Struts 1 and Struts 2 framework is their approach to handling actions. In Struts 1, the actions are defined in the struts-config.xml file, leading to a centralized configuration. In contrast, Struts 2 promotes a more flexible and annotation-based approach for defining actions, making it easier to manage and customize the application flow.

Furthermore, Struts 2 provides built-in support for AJAX functionality and client-side validation, which are not readily available in Struts 1. This enhances user experience and makes developing interactive web applications more efficient.

In conclusion, while Struts 1 is suitable for legacy applications and simpler projects, Struts 2 offers a more robust and feature-rich framework for modern web development needs.
