ProtoBuf 是谷歌开源的序列化组件.二进制,速度快.

下载地址:
https://github.com/google/protobuf/releases/tag/v3.0.0

下载protobuf-java-3.0.0.zip文件之后,需要一台Linux服务器编译

我在Linux解压该文件之后,进入目录/tmp/protobuf-3.0.0

执行
./configure
make
make install

待编译之后,进入/tmp/protobuf-3.0.0/java 目录执行

mvn clean package

然后下载
/tmp/protobuf-3.0.0/java/core/target/protobuf-java-3.0.0.jar 文件至项目.

以example的示例文件为例
cd /tmp/protobuf-3.0.0/examples
protoc --java_out=/tmp addressbook.proto

然后将/tmp下com目录添加到项目

测试代码:

package com.example.tutorial;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import com.example.tutorial.AddressBookProtos.AddressBook;
import com.example.tutorial.AddressBookProtos.Person;
public class Test {
public static void main(String[] args) throws IOException {
AddressBook.Builder addressBook = AddressBook.newBuilder();
Person.Builder personBuilder = Person.newBuilder();
personBuilder.setName("xiaohuali");
personBuilder.setId(1);
personBuilder.setEmail("youxiang");
addressBook.addPeople(personBuilder.build());
personBuilder.setName("laohuali");
personBuilder.setId(2);
personBuilder.setEmail("youxiang");
addressBook.addPeople(personBuilder.build());
//序列化过程
AddressBook book = addressBook.build();
ByteArrayOutputStream output = new ByteArrayOutputStream();
book.writeTo(output);
byte[] byteArray = output.toByteArray();
ByteArrayInputStream input = new ByteArrayInputStream(byteArray);
//反序列化
AddressBook b = AddressBook.parseFrom(input);
System.out.println(b.toString());
}
}

结果:
