是的，Spring MVC 项目通常是Web项目，用于构建Web应用程序。它基于MVC（Model-View-Controller）模式，用于处理HTTP请求和响应。
下面是一个典型的Spring MVC项目的整体文件目录结构示例：
```
- src
- main
- java
- com
- example
- controller
- HomeController.java # 控制器类
- model
- User.java # 模型类
- repository
- UserRepository.java # 数据访问接口
- service
- UserService.java # 服务接口
- UserServiceImpl.java # 服务实现类
- config
- WebConfig.java # Spring MVC配置类
- resources
- static # 静态资源文件夹（如CSS、JavaScript等）
- templates # 视图模板文件夹（如HTML、JSP等）
- application.properties # 应用程序配置文件
- webapp
- WEB-INF
- views # 视图文件夹（如JSP、Thymeleaf模板等）
- web.xml # Web应用配置文件
```
以上是一个基本的示例文件目录结构，你可以根据实际的需要进行调整和扩展。在该目录结构中：
- `src/main/java` 目录存放应用程序的Java源代码。
- `src/main/resources` 目录存放应用程序的配置文件和资源文件。
- `src/main/java/com/example/controller` 目录存放控制器（Controller）类，处理HTTP请求。
- `src/main/java/com/example/model` 目录存放模型（Model）类，定义业务实体。
- `src/main/java/com/example/repository` 目录存放数据访问接口。
- `src/main/java/com/example/service` 目录存放服务（Service）接口和实现类。
- `src/main/java/com/example/config` 目录存放Spring MVC的配置类。
- `src/main/resources/static` 目录存放静态资源文件，如CSS、JavaScript等。
- `src/main/resources/templates` 目录存放视图模板文件，如HTML、JSP等。
- `src/main/resources/application.properties` 是应用程序的配置文件，配置各种属性和参数。
- `webapp/WEB-INF` 目录是Web应用的根目录，存放Web相关的配置和资源。
- `webapp/WEB-INF/views` 目录存放JSP等视图文件。
这只是一个基本的示例，实际的Spring MVC项目的文件目录结构可能根据具体需求有所不同。你可以根据自己的项目要求和团队的约定进行调整。
希望能解答你的问题！如果还有其他疑问，请随时提问。
