您好,您可以采用以下步骤实现springboot hutool 批量压缩excel文件:
1. 首先,引入hutool的依赖。在pom.xml文件中添加以下代码:
```xml
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>
<version>4.6.9</version>
</dependency>
```
2. 编写Java代码。
```java
import cn.hutool.poi.excel.ExcelReader;
import cn.hutool.poi.excel.ExcelUtil;
import java.io.File;
import java.util.ArrayList;
import java.util.List;
import cn.hutool.core.util.ZipUtil;
public class ExcelCompressUtil {
public static void main(String[] args) {
// 待压缩的 Excel 文件列表
List<File> files = new ArrayList<>();
files.add(new File("file1.xlsx"));
files.add(new File("file2.xlsx"));
// 读取 Excel 文件并压缩
List<String> fileNames = new ArrayList<>();
for (File file : files) {
ExcelReader reader = ExcelUtil.getReader(file);
String fileName = file.getName().split("\\.")[0] + ".csv";
reader.writeToFile(fileName);
fileNames.add(fileName);
}
ZipUtil.zip(fileNames.toArray(new String[] {}), new File("compressed.zip"));
}
}
```
3. 运行代码,压缩后的文件将生成在项目根目录下。
