org.apache.commons.fileupload.FileUploadException：处理 multipart / form-data请求失败。 C：\ Program Files（x86）\ Apache Software Foundation \ Tomcat 5.0 \ upload_4133c5ef_14e0097e702__8000_00000003.tmp（系统不能 找到指定的路径）

Apache Commons FileUpload使用java.io.tmpdir system/environment变量中设置的路径作为默认上传路径。您可以更改默认上载路径。试着看看它是否解决了这个问题。查看他们的文档以获取配置详细信息。
