MultipartFile 依赖

回答: MultipartFile是Spring框架中的一个接口，用于处理文件上传。在你的代码中，使用了CommonsMultipartResolver来解析文件上传请求。要使用MultipartFile，需要引入commons-fileupload的依赖。在你的pom.xml或者build.gradle文件中添加以下依赖即可解决问题：

Maven:

<dependency>
    <groupId>commons-fileupload</groupId>
    <artifactId>commons-fileupload</artifactId>
    <version>1.4</version>
</dependency>

Gradle:

implementation 'commons-fileupload:commons-fileupload:1.4'

添加依赖后重新启动项目，就不会再报错了。如果你创建项目时依赖没有选全，或者被自己误删了，也可能导致缺少这个依赖。确保正确导入了commons-fileupload的依赖，就可以正常使用MultipartFile了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
