我解决了我的问题。我刚刚添加了commons-fileupload，但我没有添加commons-io所以我添加了它们，我的问题就解决了

<!-- Apache Commons FileUpload --> 
<dependency>
    <groupId>commons-fileupload</groupId>
    <artifactId>commons-fileupload</artifactId>
    <version>1.3.1</version>
</dependency>

<!-- Apache Commons IO --> 
<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>2.4</version>
</dependency>
