java ZipInputStream 转multipartfile

你可以使用Java的ZipInputStream类将Zip文件转换为MultipartFile对象。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.IOException;
import java.io.InputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public class ZipInputStreamToMultipartFileConverter {
    
    public MultipartFile convert(InputStream inputStream, String zipEntryName) throws IOException {
        ZipInputStream zipInputStream = new ZipInputStream(inputStream);
        ZipEntry entry;
        while ((entry = zipInputStream.getNextEntry()) != null) {
            if (entry.getName().equals(zipEntryName)) {
                byte[] entryData = zipInputStream.readAllBytes();
                MultipartFile multipartFile = new CommonsMultipartFile(entry.getName(),
                        entry.getName(), entry.getContentType(), entryData);
                return multipartFile;
            }
        }
        return null;
    }
}

使用示例：

InputStream inputStream = ...; // 读取Zip文件的数据
String zipEntryName = ...; // 指定要转换为MultipartFile的ZipEntry名称
ZipInputStreamToMultipartFileConverter converter = new ZipInputStreamToMultipartFileConverter();
MultipartFile multipartFile = converter.convert(inputStream, zipEntryName);
