一、protobuf基本操作
protobuf简介：
Protocol Buffers (a.k.a., protobuf) are Google's language-neutral, platfORM-neutral, extensible mechanism for serializing structured data.protobuf是google提供的一种跨语言、跨平台、可扩展的序列化工具。
1.1定义协议文件(部分字段)(TCPLog.proto)：
syntax = "proto2";message tcpLog{ optional int32 total_byteps = 1; optional int64 flow_start_time =2; optional int64 date =3;}1.2生成对应的Java类：
生成过程可以使用ecplise 的插件 或者 直接在控制台中使用命令生成。
命令行中生成规则如下：
protoc.exe -I=proto的输入目录 --java_out=java类输出目录 proto的输入目录包括包括proto文件生成java类如下：
// Generated by the protocol buffer compiler. DO NOT EDIT!// source: TCPLog.protopublic final class TCPLogOuterClass { private TCPLogOuterClass() {} public static void reGISterAllExtensions( com.google.protobuf.ExtensionRegistryLite registry) { } public static void registerAllExtensions( com.google.protobuf.ExtensionRegistry registry) { registerAllExtensions( (com.google.protobuf.ExtensionRegistryLite) registry);

具体示例代码如下》：
import java.io.File;import java.io.FileOutputStream;public class ProtoTest3 { public static void main(String[] args) throws Exception { //模拟将对象转成byte[]，方便传输 TCPLogOuterClass.TCPLog.Builder builder = TCPLogOuterClass.TCPLog.newBuilder(); builder.setTotalByteps(1024); builder.setFlowStartTime(1502415717l); builder.setDate(1502415717l); //序列化到文件 TCPLogOuterClass.TCPLog tcpLog= builder.build(); FileOutputStream out = new FileOutputStream(new File("D:/pb")); out.write(tcpLog.toByteArray()); out.close(); //反序列化 TCPLogOuterClass.TCPLog tcp = TCPLogOuterClass.TCPLog.parseFrom(tcpLog.toByteArray()); System.out.println(tcp);}}二、AVRO序列化基本操作：
AVRO简介：
Apache Avro™ is a data serialization system.Avro provides:Rich data structures.A compact, fast, binary data format.A container file, to store persistent data.Remote procedure call (rpc).Simple integration with dynamic languages. Code generation is not required to read or write data files nor to use or implement RPC protocols. Code generation as an optional optimization, only worth implementing for statically typed languages.Avro是一个序列化系统。丰富的数据结构、快速压缩的二进制数据格式、数据持久化存储、RPC及动态语言集成。
2.1定义协议文件(TCPLog.avro)
{"namespace": "example.avro", "type": "record", "name": "TCPLog", "fields": [ {"name": "total_byteps", "type": "int"}, {"name": "flow_start_time", "type": "long"}, {"name": "date", "type": "long"} ]}avro和protobuf一样可以生成相应语言的类文件，或直接支持动态扩张。下面以Java语言不生成类说明：
具体序列化与反序列化操作代码如下：、
package avro;import java.io.File;import org.apache.avro.Schema;import org.apache.avro.file.DataFileReader;import org.apache.avro.file.DataFileWriter;import org.apache.avro.generic.GenericData;import org.apache.avro.generic.GenericDatumReader;import org.apache.avro.generic.GenericDatumWriter;import org.apache.avro.generic.GenericRecord;import org.apache.avro.io.DatumReader;import org.apache.avro.io.DatumWriter;public class AvroTest2 {public static void main(String[] args) throws Exception { String filePath = "D:/TCPLog.avsc"; Schema schema = new Schema.Parser().parse(new File(filePath)); GenericRecord tcpLog = new GenericData.Record(schema); tcpLog.put("total_byteps", 1024); tcpLog.put("flow_start_time", 1502415717L); tcpLog.put("date", 1502415717L); System.out.println(tcpLog); // Serialize user1 and tcpLog to disk File file = new File("D:/avro"); DatumWriter<GenericRecord> datumWriter = new GenericDatumWriter<GenericRecord>(schema); DataFileWriter<GenericRecord> dataFileWriter = new DataFileWriter<GenericRecord>(datumWriter); dataFileWriter.create(schema, file); long timestart = System.currentTimeMillis(); dataFileWriter.append(tcpLog); dataFileWriter.close(); long timeend = System.currentTimeMillis(); System.out.println(timeend-timestart); // Deserialize users from disk DatumReader<GenericRecord> datumReader = new GenericDatumReader<GenericRecord>(schema); DataFileReader<GenericRecord> dataFileReader = new DataFileReader<>(new File("d:/avro"), datumReader); GenericRecord tcpLogs = null; long timestart1 = System.currentTimeMillis(); while (dataFileReader.hasNext()) { // Reuse user object by passing it to next(). This saves us from // allocating and garbage collecting many objects for files with // many items. tcpLogs = dataFileReader.next();// System.out.println("xx"+tcpLogs); } long timeend1 = System.currentTimeMillis(); System.out.println("Deserialize"+(timeend1-timestart1)); }}以下是通过对100W tcpLog序列化操作对比结论：
通过对比测试发现 avro的性能要不pb稍微好一些，且支持动态性。故技术选型上可以优先考虑。
以上是通过测试对比了pb与avro的一些性能差异，但是具体测试和机器和样本都有关系，可以参考。
以下是对比protobuf、avro、thrift的一些优缺点：
Google protobuf：优点 二进制消息，性能好/效率高（空间和时间效率都很不错） proto文件生成目标代码，简单易用 序列化反序列化直接对应程序中的数据类，不需要解析后在进行映射(XML,JSON都是这种方式) 支持向前兼容（新加字段采用默认值）和向后兼容（忽略新加字段），简化升级 支持多种语言（可以把proto文件看做IDL文件） Netty等一些框架集成缺点 官方只支持c++,JAVA和python语言绑定 二进制可读性差（貌似提供了Text_Fromat功能） 二进制不具有自描述特性 默认不具备动态特性（可以通过动态定义生成消息类型或者动态编译支持） 只涉及序列化和反序列化技术，不涉及RPC功能（类似XML或者jsON的解析器）Apache Thrift：应用 Facebook的开源的日志收集系统(scribe: https://GitHub.com/facebook/scribe) 淘宝的实时数据传输平台(TimeTunnel Http://code.taobao.org/p/TimeTunnel/wiki/index) Evernote开放接口(https://github.com/evernote/evernote-thrift) Quora(http://www.quora.com/Apache-Thrift) HBase( http://abloz.com/hbase/book.html#thrift ) …优点 支持非常多的语言绑定 thrift文件生成目标代码，简单易用 消息定义文件支持注释 数据结构与传输表现的分离，支持多种消息格式 包含完整的客户端/服务端堆栈，可快速实现RPC 支持同步和异步通信缺点 和protobuf一样不支持动态特性Apache Avro：应用 hadoop RPC （http://hadoop.apache.org/#What+Is+Apache+Hadoop%3F）优点 二进制消息，性能好/效率高 使用JSON描述模式 模式和数据统一存储，消息自描述，不需要生成stub代码（支持生成IDL） RPC调用在握手阶段交换模式定义 包含完整的客户端/服务端堆栈，可快速实现RPC 支持同步和异步通信 支持动态消息 模式定义允许定义数据的排序（序列化时会遵循这个顺序） 提供了基于Jetty内核的服务基于Netty的服务缺点 只支持Avro自己的序列化格式 语言绑定不如Thrift丰富关于Java中protobuf与avro的区别是什么就分享到这里了，希望以上内容可以对大家有一定的帮助，可以学到更多知识。如果觉得文章不错，可以把它分享出去让更多的人看到。
