What is the process of building the Spring MVC framework?
The process of setting up the Spring MVC framework is as follows:
- Create a Maven project by using Maven to build the project and adding Spring MVC dependencies.
- Configure web.xml: Set up Spring MVC’s DispatcherServlet in the web.xml file, along with other related configurations such as encoding filters, listeners, etc.
- Creating a Spring MVC configuration file involves creating a file typically named springmvc-servlet.xml, which is used to configure components such as handler mappings, handler adapters, and view resolvers for Spring MVC.
- Create a Controller: Create a handler class, annotate the class with @Controller, and annotate the methods with @RequestMapping to handle requests. These methods can return view names, model data, etc.
- Add a view resolver: Configure a view resolver in the Spring MVC configuration file to parse view names and render model data in the view.
- Create JSP pages: Develop JSP pages based on business requirements for displaying data.
- Deploy and start the project: deploy the project to containers such as Tomcat, and start the container.
- Send a request: Using a browser or other tools to send a request, the Spring MVC framework will match the corresponding handler method based on the request’s URL and the @RequestMapping annotation on the method.
- Handle requests: The Spring MVC framework will find the corresponding handler method based on the URL of the request and the @RequestMapping annotation on the method, and then execute that method.
- Render View: After the handler method has finished executing, the framework passes the model data to the view resolver, resolves the view name, and renders the model data in the view.
- Response returned: The view resolver will return the rendered view to the client, completing the request-response process.
The above is the main process of building a Spring MVC framework, which can be configured and extended according to project requirements.
