What is the function of the Struts framework?

The Struts framework is an open-source MVC framework based on Java, mainly used for developing web applications. Its purpose is to assist developers in separating the business logic of an application from the user interface, thereby improving development efficiency and code maintainability. Its specific functions include:

1. Separation of MVC: The Struts framework adopts the MVC design pattern, which separates the business logic, data model, and user interface of the application, making the development process clearer and easier to maintain.
2. Request processing: The Struts framework has a robust mechanism for handling requests, which can automatically call the corresponding Action class based on the URL or parameters of the request, and return the processing result to the client.
3. Form validation: The Struts framework comes equipped with built-in data validation functionality, allowing users to configure validation rules to check the input data on forms, thus enhancing the security and stability of the application.
4. Page redirection: The Struts framework can automatically redirect to the corresponding page based on the result of business logic processing, simplifying the operation of page redirection.
5. Internationalization support: The Struts framework offers internationalization support, allowing for the automatic display of corresponding pages and messages based on the user’s region and language.

In conclusion, the purpose of the Struts framework is to assist developers in quickly building web applications, thereby improving development efficiency and software quality.
