Spring MVC is a Java-based web framework for developing web applications. It is a sub-project of the Spring Framework that provides a model-view-controller (MVC) architecture for creating web applications, separating different aspects of the application, making development more modular and easier Maintenance and testing.
The role of Spring MVC:
- Provides a structured way to organize the code of a web application.

- Provides a flexible way to handle HTTP requests and responses, and to access and manipulate background data sources.
- Supports multiple view technologies, including JSP, Velocity, Freemarker, etc.
Advantages of Spring MVC:
- Easy to use and learn, with good scalability and flexibility.
- Integrated with Spring Framework, it can be easily integrated with other Spring projects.
- Provides powerful data binding and validation functions, which can greatly simplify the development work.
- It can be integrated with many commonly used web servers and web containers, such as Tomcat, Jetty, etc.
- Provides strong internationalization support to easily support the development of multilingual applications.
- A convenient interceptor mechanism is provided, which can intercept and process requests before, after, and during exception handling.
- Support RESTful style Web service development.
In short, Spring MVC is a powerful, easy-to-use and learning Web framework with good scalability and flexibility. Its model-view-controller (MVC) architecture can effectively separate different aspects of the application, making development more modular, easy to maintain and test, and is an excellent choice for developing web applications.
