如何在spring MVC中将字节数组转换为ZipOutputStream？

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

import javax.servlet.http.HttpServletResponse;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;

@Controller
public class MyController {

    @GetMapping("/downloadZip")
    public void downloadZip(HttpServletResponse response) throws IOException {
        // 创建字节数组
        byte[] byteArray = createByteArray();

        // 设置响应头信息
        response.setContentType("application/zip");
        response.setHeader("Content-Disposition", "attachment; filename=myfile.zip");

        // 创建字节流和压缩输出流
        ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
        ZipOutputStream zipStream = new ZipOutputStream(byteStream);

        // 将字节数组写入压缩包
        ZipEntry entry = new ZipEntry("file1.txt");
        zipStream.putNextEntry(entry);
        zipStream.write(byteArray);
        zipStream.closeEntry();

        // 完成压缩包的创建
        zipStream.finish();

        // 将压缩包写入响应输出流
        response.getOutputStream().write(byteStream.toByteArray());
        response.getOutputStream().flush();
        response.getOutputStream().close();
    }

    private byte[] createByteArray() {
        // 创建字节数组并返回
        return new byte[]{1, 2, 3, 4, 5};
    }
}
