What are the basic characteristics of the struts framework?

Basic features of the Struts framework include:

1. Struts utilizes the MVC (Model-View-Controller) architecture pattern, dividing the application into three parts: model, view, and controller, which provides good code separation and maintainability.
2. Controller: The Struts framework provides a front controller, namely ActionServlet, to receive and dispatch requests. The controller is responsible for parsing request parameters, selecting the appropriate Action to handle the request, and returning the processing results to the view.
3. Dynamic page generation: The Struts framework offers tag libraries and form validation features, making it easy to generate dynamic pages.
4. Form validation: The Struts framework comes with built-in form validation functionality that allows for validating the validity of user input data through configuration files or annotations.
5. Central configuration: The Struts framework uses XML configuration files to manage the application’s configuration information, including mapping relationships between URLs and Actions, form validation rules, etc.
6. Data binding: The Struts framework supports automatic binding of request parameters to the properties of the Action, simplifying the process of handling data.
7. Internationalization support: The Struts framework offers internationalization support, which allows for multiple language support through configuration files.
8. Exception handling: The Struts framework offers a mechanism for handling exceptions, which can be used to handle exceptions in the application uniformly and prevent the application from crashing.
9. Interceptor: The Struts framework offers an interceptor mechanism that allows for pre-processing and post-processing of requests, enabling functions such as logging and permission validation.
10. Supports multiple view technologies: The Struts framework supports various view technologies such as JSP, Velocity, and Freemarker, allowing users to choose the suitable view technology based on their needs.
