Spring Boot项目构建报错：org.springframework.boot包不存在求助

我跟着教程开发电影相关API的Spring Boot项目，构建时出现以下错误（个人信息已用<>替换）：

C:\Users\<>\Desktop\Movie_App\movies\movies\src\main\java\dev\<>\movies\MoviesApplication.java:3:32
java: package org.springframework.boot does not exist

C:\Users\<>\Desktop\Movie_App\movies\movies\src\main\java\dev\<>\movies\MoviesApplication.java:4:46
java: package org.springframework.boot.autoconfigure does not exist
C:\Users\<>\Desktop\Movie_App\movies\movies\src\main\java\dev\<>\movies\MoviesApplication.java:6:2
java: cannot find symbol
  symbol: class SpringBootApplication
C:\Users\<>\Desktop\Movie_App\movies\movies\src\main\java\dev\<>\movies\MoviesApplication.java:10:9
java: cannot find symbol
  symbol:   variable SpringApplication
  location: class dev.<>.movies.MoviesApplication

项目的pom.xml文件内容如下：

我已经尝试过以下方法但问题未解决：

• 在Build,Execution,Deployment->Java Compiler->Module中确保目标字节码版本为17；
• 通过Maven侧边栏重载所有Maven项目；
• 确认使用的JDK版本为17。

可行的解决步骤： #

1. 执行Maven命令强制更新依赖并重新构建：

   mvn clean install -U
   

2. 检查IDE的Maven配置，关闭离线模式：打开Settings -> Build, Execution, Deployment -> Build Tools -> Maven，取消勾选"Work offline"选项，确保Maven可以正常下载依赖。
3. 验证项目的SDK配置：进入File -> Project Structure -> Project，确认Project SDK和Project language level都设置为Java 17。
4. 清理本地Maven缓存：删除本地仓库中Spring Boot相关的缓存目录（例如~/.m2/repository/org/springframework/boot），然后重新执行mvn clean install。
5. 确认IDE正确识别了项目的pom.xml：右键点击pom.xml文件，选择"Add as Maven Project"，确保项目被正确标记为Maven项目。
