使用Protocol Buffers的GzipOutputStream和GzipInputStream的简单工作示例

import com.google.protobuf.Person;
import java.io.ByteArrayOutputStream;
import java.io.GZIPOutputStream;
import java.io.IOException;

public class GzipOutputStreamExample {
    public static void main(String[] args) throws IOException {
        Person person = Person.newBuilder()
                .setName("John Doe")
                .setAge(30)
                .build();

        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        GZIPOutputStream gzipOutputStream = new GZIPOutputStream(byteArrayOutputStream);

        person.writeTo(gzipOutputStream);
        gzipOutputStream.close();

        byte[] compressedData = byteArrayOutputStream.toByteArray();
        System.out.println("Compressed data: " + compressedData);
    }
}

import com.google.protobuf.Person;
import java.io.ByteArrayInputStream;
import java.io.GZIPInputStream;
import java.io.IOException;

public class GzipInputStreamExample {
    public static void main(String[] args) throws IOException {
        byte[] compressedData = new byte[]{ /* Gzip压缩的二进制数据 */ };

        ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(compressedData);
        GZIPInputStream gzipInputStream = new GZIPInputStream(byteArrayInputStream);

        Person person = Person.parseFrom(gzipInputStream);
        System.out.println("Person: " + person);
    }
}
