Marshalling序列化框架简单实现
1.导入相关jar包
maven项目直接添加依赖即可。
org.jboss.marshalling
jboss-marshalling-osgi
2.0.0.Beta5
2.创建序列化传输的类
//记得要实现Serializable接口
public class UserInfo implements Serializable {
private String username;
private String age;
public String getUsername() {
return username;
}
public String getAge() {
return age;
}
public void setUsername(String username) {
this.username = username;
}
public void setAge(String age) {
this.age = age;
}
public UserInfo(String username, String age) {
super();
this.username = username;
this.age = age;
}
public UserInfo(){
}
@Override
public String toString() {
return "UserInfo [username=" + username + ", age=" + age + "]";
}
}
3.编写创建MarshallingEncoder和MarshallingDecoder的工厂类
public class MarshallingCodeFactory {
public static MarshallingEncoder getEncoder(){
//这里表示的是支持java serial对象的序列化。所以我们传输的对象要实现Serializable接口
MarshallerFactory factory = Marshalling.getProvidedMarshallerFactory("serial");
MarshallingConfiguration configuration = new MarshallingConfiguration();
configuration.setVersion(5);
MarshallerProvider provider = new DefaultMarshallerProvider(factory, configuration);
MarshallingEncoder encoder = new MarshallingEncoder(provider);
return encoder;
}
public static MarshallingDecoder getDecoder(){
MarshallerFactory factory = Marshalling.getProvidedMarshallerFactory("serial");
MarshallingConfiguration configuration = new MarshallingConfiguration();
configuration.setVersion(5);
UnmarshallerProvider provider = new DefaultUnmarshallerProvider(factory, configuration);
MarshallingDecoder decoder = new MarshallingDecoder(provider);
return decoder;
}
4.Server端
package cn.senninha.concurrent.server;
import cn.senninha.concurrent.code.MarshallingCodeFactory;
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.marshalling.MarshallingDecoder;
import io.netty.handler.codec.marshalling.MarshallingEncoder;
public class TimeServerMarshalling {
public void bind(int port) throws Exception {
EventLoopGroup bossGruop = new NioEventLoopGroup();
EventLoopGroup workGroup = new NioEventLoopGroup();
ServerBootstrap bootstrap = new ServerBootstrap();
bootstrap.group(bossGruop, workGroup).channel(NioServerSocketChannel.class)
.option(ChannelOption.SO_BACKLOG, 1024).childHandler(new ChildChannelHandler());
try {
ChannelFuture future = bootstrap.bind(port).sync();
future.channel().closeFuture().sync();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
bossGruop.shutdownGracefully();
workGroup.shutdownGracefully();
}
}
private class ChildChannelHandler extends ChannelInitializer {
@Override
protected void initChannel(SocketChannel ch) throws Exception {
// TODO Auto-generated method stub
//这里添加marshalling的序列化支持
MarshallingEncoder encoder = MarshallingCodeFactory.getEncoder();
MarshallingDecoder decoder = MarshallingCodeFactory.getDecoder();
ch.pipeline().addLast(encoder);
ch.pipeline().addLast(decoder);
ch.pipeline().addLast(new TimeServerHandler());
}
}
public static void main(String[] args) {
int port = 12580;
try {
new TimeServerMarshalling().bind(port);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
对应的serverhanlder：
package cn.senninha.concurrent.server;
import java.nio.ByteBuffer;
import org.msgpack.MessagePack;
import org.omg.Messaging.SyncScopeHelper;
import io.netty.buffer.ByteBuf;
import io.netty.buffer.ByteBufUtil;
import io.netty.buffer.Unpooled;
import io.netty.channel.ChannelHandlerAdapter;
import io.netty.channel.ChannelHandlerContext;
public class TimeServerHandler extends ChannelHandlerAdapter {
@Override
public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
// TODO Auto-generated method stub
// ByteBuf in = (ByteBuf) msg;
try {
System.out.println(msg);
String remsg = new String("has receive");
ctx.write(remsg);
ctx.flush();
} catch (Exception e) {
e.printStackTrace();
}finally {
}
}
@Override
public void channelReadComplete(ChannelHandlerContext ctx) throws Exception {
// TODO Auto-generated method stub
ctx.flush();
}
}
5.Client端
package cn.senninha.concurrent.client;
import java.net.UnknownHostException;
import cn.senninha.concurrent.code.MarshallingCodeFactory;
import io.netty.bootstrap.Bootstrap;
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.NioSocketChannel;
import io.netty.handler.codec.marshalling.MarshallingDecoder;
import io.netty.handler.codec.marshalling.MarshallingEncoder;
public class NettyClientMarshalling {
private void bind(int port,String host){
EventLoopGroup group = new NioEventLoopGroup();
Bootstrap b = new Bootstrap();
b.group(group).channel(NioSocketChannel.class)
.option(ChannelOption.TCP_NODELAY, true).handler(new ClientHandlerInit());
try {
ChannelFuture f = b.connect(host, port).sync();
f.channel().closeFuture().sync();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally{
group.shutdownGracefully();
}
}
private class ClientHandlerInit extends ChannelInitializer{
@Override
protected void initChannel(SocketChannel ch) throws Exception {
// TODO Auto-generated method stub
//添加对marshalling框架的支持
MarshallingEncoder encoder = MarshallingCodeFactory.getEncoder();
MarshallingDecoder decoder = MarshallingCodeFactory.getDecoder();
ch.pipeline().addLast(encoder);
ch.pipeline().addLast(decoder);
ch.pipeline().addLast(new ClientHandler());
}
}
public static void main(String[] args) throws UnknownHostException {
// TODO Auto-generated method stub
NettyClientMarshalling client = new NettyClientMarshalling();
client.bind(12580,"localhost");
}
}
对应的clienthandler代码：
package cn.senninha.concurrent.client;
import cn.senninha.concurrent.code.model.UserInfo;
import io.netty.channel.ChannelHandlerAdapter;
import io.netty.channel.ChannelHandlerContext;
import javassist.bytecode.ByteArray;
public class ClientHandler extends ChannelHandlerAdapter {
private byte[] request = ("senninha" + System.getProperty("line.separator")).getBytes();
@Override
public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
// TODO Auto-generated method stub
System.out.println(msg);
}
@Override
public void channelActive(ChannelHandlerContext ctx) throws Exception {
// TODO Auto-generated method stub
for (int i = 0; i < 500; i++) {
UserInfo userInfo = new UserInfo();
userInfo.setAge(i + "year");
userInfo.setUsername("senninha");
ctx.write(userInfo);
ctx.flush();
}
System.out.println("-----------------send over-----------------");
}
@Override
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception {
// TODO Auto-generated method stub
System.out.println("error");
}
}
6.运行
UserInfo [username=senninha, age=0year]
UserInfo [username=senninha, age=1year]
UserInfo [username=senninha, age=2year]
UserInfo [username=senninha, age=3year]
UserInfo [username=senninha, age=4year]
