当我在线部署文件上传程序时，文件上传程序在本地电脑上工作正常，但出现错误，即

org.apache.commons.fileupload.FileUploadException: Processing of multipart/form-data request failed. C:\Program Files (x86)\Apache Software Foundation\Tomcat 5.0 \upload_4133c5ef_14e0097e702__8000_00000003.tmp (The system cannot find the path specified)

谁能帮我解决这个问题。谢谢

最佳答案

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。您可以更改默认上传路径。尝试看看是否能解决问题。检查他们的文档以获取配置详细信息。
