Struts2

Struts2 is an open-source web application framework used for building Java-based enterprise applications. It is part of the Apache Software Foundation's suite of tools and is designed to facilitate the development of maintainable and scalable web applications following the Model-View-Controller (MVC) architecture.

Originally developed as a successor to the original Struts framework, Struts2 was created through the combination of the WebWork framework and the original Struts framework. The development of Struts2 aimed to improve extensibility, ease of use, and configuration flexibility. It provides a rich set of features, including simplified configuration via annotations, comprehensive tag libraries, and support for RESTful URL mappings.

Struts2 integrates seamlessly with other Java EE technologies and supports various view technologies such as JSP, FreeMarker, and Velocity. It employs interceptors to handle processing logic before and after executing actions, enabling modular response handling and validation. The framework also offers built-in support for validation, error handling, and internationalization.

Since its release, Struts2 has become popular among Java developers for its simplicity and robustness. It is widely used in enterprise environments for developing web applications that require a clear separation of concerns and flexible architecture. However, with the evolving landscape of web development, newer frameworks such as Spring MVC and JSF have also gained popularity.

Despite the emergence of alternative frameworks, Struts2 remains a significant part of the Java web development ecosystem, valued for its mature features and active community support. The latest versions continue to enhance security, performance, and compatibility with modern development practices.
