protobuf是由Google开发的一套对数据结构进行序列化的方法,可用做通信协议,数据存储格式,等等。其特点是不限语言、不限平台、扩展性强

Netty也提供了对Protobuf的天然支持,我们今天就写一个简单的示例,简单地了解一下Netty对Google的protoBuf的支持

场景设置:

我们的示例场景很简单的:客户端发送一个信息,这个信息用Protobuf来做序列化,然后服务器端接收这个信息,解码,读取信息

protobuf与xml,json这样的数据格式一样,都有自己的一套语法,且语法很简单,很容易掌握,xml文件的后缀名是xml,json的后缀名是json,以此类推,那么protobuf的后缀名就是proto

关于proto的基本语法与Java的bean很像,详细可以参考官网,可以看下这篇博客:http://blog.sina.com.cn/s/blog_9b0604b40101qm35.html

第一步:定义proto文件
现在我们定义一个类似Java bean的proto文件,我们定义一个“富人”类,他有多辆车,我们先按照语法,写一个RichMan.proto,如下面的代码清单所示:

package netty;

option java_package = "com.lyncc.netty.codec.protobuf.demo";
option java_outer_classname = "RichManProto"; message RichMan { required int32 id = 1;
required string name = 2;
optional string email = 3; enum CarType {
AUDI = 0;
BENZ = 1;
LAMBORGHINI = 2;
DASAUTO = 3;
} message Car {
required string name = 1;
optional CarType type = 2 [default = BENZ];
} repeated Car cars = 4; }

给出上面代码的一些基本解释:

1)java_package值得是该文件生成的java文件的包路径
2)java_outer_classname值的是生成的class的名称
3)message和enum是它的基本类型,很类似于java的class和枚举
4)required表名这个字段是必须的,option表明这个字段可选,default表明这个字段有默认值
5)repeat表明这个字段可以重复,类似于java中的List,该例子中Car的声明中,就相当于java中的List<Car>
6)每个声明的后面的数字,例如1,2,3, 4等等,同级的声明不能重复
总而言之,这个“类”定义了一个富人,该富人有id,名称,邮箱,而且该富人有多个名车,这些名车的类型有奥迪,奔驰,兰博基尼,大众
好了,到目前为止,proto我们已经定义好了,Google提供了一个类似脚本的工具,可以使我们将proto文件转化成java文件

第二步:将proto文件转化成java文件(参考上节)

将生成的文件拷贝至项目中,参考生成文件如下:

第三步:编写Netty服务端ProtoBufServer 

package com.ssy.netty.proto;

import io.netty.bootstrap.ServerBootstrap;
import io.netty.channel.ChannelFuture;
import io.netty.channel.ChannelInitializer;
import io.netty.channel.ChannelOption;
import io.netty.channel.EventLoopGroup;
import io.netty.channel.nio.NioEventLoopGroup;
import io.netty.channel.socket.SocketChannel;
import io.netty.channel.socket.nio.NioServerSocketChannel;
import io.netty.handler.codec.protobuf.ProtobufDecoder;
import io.netty.handler.codec.protobuf.ProtobufVarint32FrameDecoder;
import io.netty.handler.logging.LogLevel;
import io.netty.handler.logging.LoggingHandler; public class ProtoBufServer { public void bind(int port) throws Exception {
// 配置服务端的NIO线程组
EventLoopGroup bossGroup = new NioEventLoopGroup();
EventLoopGroup workerGroup = new NioEventLoopGroup();
try {
ServerBootstrap b = new ServerBootstrap();
b.group(bossGroup, workerGroup).channel(NioServerSocketChannel.class).option(ChannelOption.SO_BACKLOG, 100)
.handler(new LoggingHandler(LogLevel.INFO)).childHandler(new ChannelInitializer<SocketChannel>() {
@Override
public void initChannel(SocketChannel ch) {
ch.pipeline().addLast(new ProtobufVarint32FrameDecoder());
ch.pipeline().addLast(new ProtobufDecoder(RichManProto.RichMan.getDefaultInstance()));
ch.pipeline().addLast(new ProtoBufServerHandler());
}
}); // 绑定端口,同步等待成功
ChannelFuture f = b.bind(port).sync(); System.out.println("init start");
// 等待服务端监听端口关闭
f.channel().closeFuture().sync();
} finally {
// 优雅退出,释放线程池资源
bossGroup.shutdownGracefully();
workerGroup.shutdownGracefully();
}
} public static void main(String[] args) throws Exception {
int port = 8080;
if (args != null && args.length > 0) {
try {
port = Integer.valueOf(args[0]);
} catch (NumberFormatException e) {
// 采用默认值
}
}
new ProtoBufServer().bind(port);
} }

第四步:编写 ProtoBufServerHandler

package com.ssy.netty.proto;
import io.netty.channel.ChannelHandlerContext;
import io.netty.channel.ChannelInboundHandlerAdapter; import java.util.List; import com.ssy.netty.proto.RichManProto.RichMan.Car; public class ProtoBufServerHandler extends ChannelInboundHandlerAdapter { @Override
public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
RichManProto.RichMan req = (RichManProto.RichMan) msg;
System.out.println(req.getName()+"他有"+req.getCarsCount()+"量车");
List<Car> lists = req.getCarsList();
if(null != lists) { for(Car car : lists){
System.out.println(car.getName());
}
}
} @Override
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) {
cause.printStackTrace();
ctx.close();
} }

第五步:编写客户端程序

package com.ssy.netty.proto;
import io.netty.channel.ChannelHandlerContext;
import io.netty.channel.ChannelInboundHandlerAdapter; import java.util.ArrayList;
import java.util.List; import com.ssy.netty.proto.RichManProto.RichMan.Car;
import com.ssy.netty.proto.RichManProto.RichMan.CarType; public class ProtoBufClientHandler extends ChannelInboundHandlerAdapter { @Override
public void channelActive(ChannelHandlerContext ctx) {
System.out.println("=======================================");
RichManProto.RichMan.Builder builder = RichManProto.RichMan.newBuilder();
builder.setName("王思聪");
builder.setId(1);
builder.setEmail("[email protected]"); List<RichManProto.RichMan.Car> cars = new ArrayList<RichManProto.RichMan.Car>();
Car car1 = RichManProto.RichMan.Car.newBuilder().setName("上海大众超跑").setType(CarType.DASAUTO).build();
Car car2 = RichManProto.RichMan.Car.newBuilder().setName("Aventador").setType(CarType.LAMBORGHINI).build();
Car car3 = RichManProto.RichMan.Car.newBuilder().setName("奔驰SLS级AMG").setType(CarType.BENZ).build(); cars.add(car1);
cars.add(car2);
cars.add(car3); builder.addAllCars(cars);
ctx.writeAndFlush(builder.build());
} @Override
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) {
cause.printStackTrace();
ctx.close();
} }

好了,到此为止,所有的代码已经写完毕了,我们运行测试一下:

至此,Google Protobuf与Netty的结合示例已完成,下节我们介绍Apache Thrift
