As an AI language model, I cannot access or upload files. However, if you are experiencing this issue, it means that the file you were trying to access or upload has no content. This could be due to a number of reasons, such as a technical error during the upload process or the file being mistakenly saved as an empty file. To resolve this issue, you can try re-uploading the file or creating a new file with the required content. If the issue persists, you may need to seek technical assistance or contact the person who supplied the file for further guidance.

the supplied file was empty (zero bytes long)
“the supplied file was empty (zero bytes long)”是一个错误信息,它表示所提供的文件大小为零字节,也就是文件内容为空。通常出现这个错误可能有以下原因:
1. 文件被意外删除或损坏:如果文件包含在其他文件夹或设备中,可能在拷贝或传输过程中出错,导致文件内容为空。
2. 文件损坏或格式不正确:可能文件格式不支持或损坏,导致文件无法正确读取。
3. 账号间的问题:如果使用云服务,账户权限问题可能导致文件无法正常传输或下载。
我们需要检查文件的来源和传输过程是否存在问题,以及文件的格式和内容是否正确。如果需要,可以重新获取或制作文件,或者进行额外的数据恢复工作。在工作和学习中谨慎处理文件和数据,可以避免出现文件为空的情况。
报错The supplied file was empty (zero bytes long)
如果你遇到了 "The supplied file was empty (zero bytes long)" 报错,那么可能是为你提供的 Excel 文件是空或者文件内容为空。
在使用 EasyExcel 解析文件之前,建议你先检查一下文件是否存在以及文件的大小是否大于零。你可以使用以下代码片段来检查文件:
```java
import java.io.File;
public class ExcelParser {
public static void main(String[] args) {
String fileName = "path/to/your/excel/file.xlsx";
// 检查文件是否存在且大小大于零
File file = new File(fileName);
if (!file.exists() || file.length() == 0) {
System.out.println("Excel file is empty or does not exist.");
return;
}
// 继续解析 Excel 文件的代码...
}
}
```
确保替换 `path/to/your/excel/file.xlsx` 为你实际的 Excel 文件路径。此代码片段会检查文件是否存在以及文件大小是否大于零。如果文件为空或者不存在,将会打印出相应的错误消息。
