我有一个上传 java servlet，它在 windows 上运行代码时将文件写入临时目录，它工作正常，但是当我在 CentOS 上运行它时，我得到下面的 java.io.FileNotFoundException 错误。servlet 没有将文件写入 /usr/local/jakarta/apache-tomcat-7.0.26/temp 。我尝试将每个目录权限设置为 rwxrwxrwx 但仍然无效。知道可能是什么问题吗？

您的 System.getProperty("java.io.tmpdir") 位置不存在。它只发生在超过 10 KB 的文件上，因为只有当文件大小超过 10 KB 时，tomcat 才会尝试写入磁盘。

我希望这有帮助

我正在使用由 GWT gwtupload servlet 创建的 FileItem 导致错误。我创建了一个临时文件并将 FileItem 的内容复制到我的新临时文件中。

File file = File.createTempFile("upload-", ".xls");
item.write(file);
