java zipEntry转multipartfile

你可以使用Java的ZipInputStream来将ZipEntry转换为MultipartFile。下面是一个示例代码：

import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.multipart.commons.CommonsMultipartFile;

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public class ZipEntryToMultipartFileConverter {
    
    public MultipartFile convert(ZipEntry zipEntry, byte[] zipData) throws IOException {
        // 读取zipEntry的数据
        ByteArrayInputStream inputStream = new ByteArrayInputStream(zipData);
        ZipInputStream zipInputStream = new ZipInputStream(inputStream);
        ZipEntry entry;
        while ((entry = zipInputStream.getNextEntry()) != null) {
            if (entry.getName().equals(zipEntry.getName())) {
                byte[] entryData = zipInputStream.readAllBytes();
                // 将zipEntry的数据转换为MultipartFile
                MultipartFile multipartFile = new CommonsMultipartFile(entry.getName(),
                        entry.getName(), zipEntry.getContentType(), entryData);
                return multipartFile;
            }
        }
        return null;
    }
}

使用示例：

ZipEntry zipEntry = ...; // 从Zip文件中获取ZipEntry对象
byte[] zipData = ...; // 读取Zip文件的数据
ZipEntryToMultipartFileConverter converter = new ZipEntryToMultipartFileConverter();
MultipartFile multipartFile = converter.convert(zipEntry, zipData);
