用pako.js压缩字符串，如何在后端用java解开？

const pako = require('pako');

// 假设这是你通过pako压缩过的数据
const compressedData = pako.deflate('这是一个压缩的字符串', { to: 'string' });

// 将compressedData发送到服务器

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.util.zip.DataFormatException;
import java.util.zip.Inflater;

public class Decompressor {
    public static String decompress(String compressedStr) {
        byte[] compressedBytes = Base64.getDecoder().decode(compressedStr);
        ByteArrayInputStream bis = new ByteArrayInputStream(compressedBytes);
        Inflater inflater = new Inflater();
        ByteArrayOutputStream bos = new ByteArrayOutputStream(compressedBytes.length);

        try {
            byte[] buffer = new byte[1024];
            int len;
            inflater.setInput(bis);
            while (!inflater.needsInput()) {
                len = inflater.inflate(buffer);
                if (len <= 0) {
                    break;
                }
                bos.write(buffer, 0, len);
            }
            bis.close();
            inflater.end();

            return new String(bos.toByteArray(), "UTF-8");
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

    public static void main(String[] args) {
        String compressedStr = "eJzT0yMAAGTvBe8="; // 这里应该是前端发送过来的压缩数据
        String decompressedStr = decompress(compressedStr);
        System.out.println(decompressedStr);
    }
}
