Apache Struts 2 is a powerful Java web application framework built on the MVC (Model-View-Controller) architecture, designed to simplify the development of dynamic web pages. It is part of the Apache Software Foundation's projects and widely used for enterprise-level applications.
🎯 Core Concepts
- MVC Architecture: Separates application logic, data, and UI for organized code structure.
- Action Classes: Handle user requests and perform business logic.
- Result Types: Define how the application responds (e.g., JSP, JSON, or plain text).
- Interceptors: Enhance functionality without modifying action code directly.
✅ Key Features
- Easy Configuration: XML-based setup for actions and results.
- Rich Plugin Ecosystem: Extends capabilities with plugins like file upload or validation.
- Integration with Other Technologies: Works seamlessly with Hibernate, Spring, and jQuery.
- Security Support: Built-in features for preventing XSS and CSRF attacks.
📚 Use Cases
- Enterprise Applications: Scalable for complex business systems.
- Legacy System Modernization: Simplifies migration from older frameworks.
- RESTful APIs: Efficient for building lightweight, HTTP-based services.
