Google Protocol Buffers Java实例
Google Protocol Buffers 是 Google 公司开发的一款简洁、高效的数据序列化/反序列化的工具，有着跨平台、可扩展的优点，尤其适合作为数据存储和RPC数据交换格式。目前，已经被 Hadoop 用作其 RPC 模块的基础依赖。
本文将根据网络上流行的一个例子，用Java程序来直观地展示如何用 Protocol Buffers 进行代码生成、数据序列化存储以及数据反序列化读取的过程。
步骤：
1、环境搭建：
本文在 Windows 系统下进行开发，因此下载https://protobuf.googlecode.com/files/protoc-2.5.0-win32.zip。解压后便可直接使用：
2、创建好工作目录
注：父目录路径为D:\Study\ComputerStudy\BigData_Cloud\Protobuf\practise
3、编辑proto 文件 D:\Study\ComputerStudy\BigData_Cloud\Protobuf\practise\proto\addressbook.proto，以定义message对象
package tutorial;
option java_package = "study.java.arithmetic.protobuf";
option java_outer_classname = "AddressBookProtos";
message Person {
required string name = 1;
required int32 id = 2; // Unique ID number for this person.
optional string email = 3;
enum PhoneType {
MOBILE = 0;
HOME = 1;
WORK = 2;
}
message PhoneNumber {
required string number = 1;
optional PhoneType type = 2 [default = HOME];
}
repeated PhoneNumber phone = 4;
}
// Our address book file is just one of these.
message AddressBook {
repeated Person person = 1;
}
4、通过proto文件自动生成java代码
命令：protoc -I=D:\\Study\\ComputerStudy\\BigData_Cloud\\Protobuf\\practise\\ --java_out=D:\\Study\\ComputerStudy\\BigData_Cloud\\Protobuf\\practise\\src D:\\Study\\ComputerStudy\\BigData_Cloud\\Protobuf\\practise\\proto\\addressbook.proto
注：AddressBookProtos.java代码在本文最后的“附-1”部分
5、创建 Java 工程，并将protobuf-java-2.5.0.jar包加入到工程classpath中。然后，将自动生成的AddressBookProtos.java添加进工程
6、在工程的同一个文件夹下，创建AddPerson.java类——该类负责将数据写入PB的存储文件中：
package study.java.arithmetic.protobuf;
import study.java.arithmetic.protobuf.AddressBookProtos.AddressBook;
import study.java.arithmetic.protobuf.AddressBookProtos.Person;
import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.InputStreamReader;
import java.io.IOException;
import java.io.PrintStream;
class AddPerson{
// This function fills in a Person message based on user input.
static Person PromptForAddress(BufferedReader stdin,PrintStream stdout)throws IOException{
Person.Builder person = Person.newBuilder();
stdout.print("Enter person ID: ");
person.setId(Integer.valueOf(stdin.readLine()));
stdout.print("Enter name: ");
person.setName(stdin.readLine());
stdout.print("Enter email address (blank for none): ");
String email = stdin.readLine();
if (email.length() > 0){
person.setEmail(email);
}
while (true){
stdout.print("Enter a phone number (or leave blank to finish): ");
String number = stdin.readLine();
if (number.length() == 0){
break;
}
Person.PhoneNumber.Builder phoneNumber = Person.PhoneNumber.newBuilder().setNumber(number);
stdout.print("Is this a mobile, home, or work phone? ");
String type = stdin.readLine();
if (type.equals("mobile")){
phoneNumber.setType(Person.PhoneType.MOBILE);
} else if (type.equals("home")) {
phoneNumber.setType(Person.PhoneType.HOME);
} else if (type.equals("work")) {
phoneNumber.setType(Person.PhoneType.WORK);
} else {
stdout.println("Unknown phone type. Using default.");
}
person.addPhone(phoneNumber);
}
return person.build();
}
// Main function: Reads the entire address book from a file, adds one person based on user input,
//then writes it back out to the same file.
public static void main(String[] args) throws Exception{
if (args.length != 1) {
System.err.println("Usage: AddPerson ADDRESS_BOOK_FILE");
System.exit(-1);
}
AddressBook.Builder addressBook = AddressBook.newBuilder();
// Read the existing address book.
try {
addressBook.mergeFrom(new FileInputStream(args[0]));
} catch (FileNotFoundException e) {
System.out.println(args[0] + ": File not found. Creating a new file.");
}
// Add an address.
addressBook.addPerson(
PromptForAddress(new BufferedReader(new InputStreamReader(System.in)), System.out));
// Write the new address book back to disk.
FileOutputStream output = new FileOutputStream(args[0]);
addressBook.build().writeTo(output);
output.close();
}
}
7、执行AddPerson.java类的main方法，并输入参数“D:\\Study\\ComputerStudy\\BigData_Cloud\\Protobuf\\practise\\file\\addressbook”作为数据存储文件的位置。
根据提示，逐一输入 Person 对象的属性值：
最后，该类将Person对象数据写入到指定的PB的存储文件D:\\Study\\ComputerStudy\\BigData_Cloud\\Protobuf\\practise\\file\\addressbook中。文件格式为二进制：
8、编写 Java 类ListPeople.java，用于从存储文件中反序列化对象
ListPeople.java：
package study.java.arithmetic.protobuf;
import study.java.arithmetic.protobuf.AddressBookProtos.AddressBook;
import study.java.arithmetic.protobuf.AddressBookProtos.Person;
import java.io.FileInputStream;
public class ListPeople {
// Iterates though all people in the AddressBook and prints info about them.
static void Print(AddressBook addressBook) {
for (Person person: addressBook.getPersonList()) {
System.out.println("Person ID: " + person.getId());
System.out.println(" Name: " + person.getName());
if (person.hasEmail()) {
System.out.println(" E-mail address: " + person.getEmail());
}
for (Person.PhoneNumber phoneNumber : person.getPhoneList()) {
switch (phoneNumber.getType()) {
case MOBILE:
System.out.print(" Mobile phone #: ");
break;
case HOME:
System.out.print(" Home phone #: ");
break;
case WORK:
System.out.print(" Work phone #: ");
break;
}
System.out.println(phoneNumber.getNumber());
}
}
}
// Main function: Reads the entire address book from a file and prints all the information inside.
/**
* @param args
* @throws Exception
*/
public static void main(String[] args) throws Exception {
if (args.length != 1) {
System.err.println("Usage: ListPeople ADDRESS_BOOK_FILE");
System.exit(-1);
}
// Read the existing address book.
AddressBook addressBook = AddressBook.parseFrom(new FileInputStream(args[0]));
Print(addressBook);
}
}
9、使用ListPeople.java 从存储文件D:\\Study\\ComputerStudy\\BigData_Cloud\\Protobuf\\practise\\file\\addressbook中反序列化Person对象：

// Generated by the protocol buffer compiler. DO NOT EDIT!
// source: proto/addressbook.proto
package study.java.arithmetic.protobuf;
public final class AddressBookProtos {
private AddressBookProtos() {}
