Struts 2.5 Framework Overview
Struts 2.5, the latest version of the Java Web application framework developed by the Apache Software Foundation, is designed for building enterprise-level Java Web applications using the MVC (Model-View-Controller) design pattern. Key features of Struts 2.5 include:
1. **MVC Pattern**: It adheres to the MVC architecture, dividing application logic into model, view, and controller components for better code organization and reuse.
2. **Interceptors**: Core to Struts 2.5, interceptors are used to execute common tasks such as authentication, logging, and performance monitoring before and after Action execution.
3. **Configuration Flexibility**: Supports both XML and annotation-based configuration, allowing developers to choose based on project complexity.
4. **Plugin Ecosystem**: Includes plugins like Tiles for layout, Freemarker/Velocity for templating, and JSON/REST for web services.
5. **Error Handling and Internationalization**: Offers robust error handling and supports multilingual environments.
6. **Enhanced Security**: Addresses security vulnerabilities from previous versions with stricter input validation and improved security configurations.
7. **Performance Optimization**: Improves performance through better algorithms and reduced memory usage.
8. **Dependency Injection (DI)**: Compatible with Spring and other DI containers for clearer dependency management.
9. **Action and Result**: Defines custom Action classes to process user requests and Result types to handle responses.
10. **Version Compatibility**: Maintains backward compatibility with earlier versions to facilitate smooth upgrades.
Struts 2.5 provides a comprehensive framework for developing and managing complex web applications, allowing developers to focus on business logic rather than underlying infrastructure. For detailed implementation, review the 'struts-2.5.18' package.
