messagePack编解码

首先引入javassist-3.20.0-GA.jar与msgpack-0.6.12.jar两个包，然后就可以使用.

 package com.ming.netty.code;

 import java.io.Serializable;
 import java.nio.ByteBuffer;

 /**
  * 一个普通学生类
  * @author mingge
  *
  */
 public class Student implements Serializable{
     private static final long serialVersionUID = 1L;

     private String stuName;

     public String getStuName() {
         return stuName;
     }

     public void setStuName(String stuName) {
         this.stuName = stuName;
     }

     public byte[] codeC(){
         ByteBuffer buffer=ByteBuffer.allocate(1024);
         byte[] value=this.getStuName().getBytes();
         buffer.putInt(value.length);
         buffer.put(value);
         buffer.flip();
         value=null;
         byte[] result=new byte[buffer.remaining()];
         buffer.get(result);
         return result;
     }

 }

 package com.ming.netty.code;

 import java.io.ByteArrayOutputStream;
 import java.io.ObjectOutputStream;
 import java.util.ArrayList;
 import java.util.List;

 import org.msgpack.MessagePack;
 import org.msgpack.template.Templates;

 public class TestMsgPack {

     public static void main(String[] args) throws Exception{
         List<String> list=new ArrayList<>();
         list.add("a");
         list.add("b");
         list.add("c");

         ByteArrayOutputStream bos=new ByteArrayOutputStream();
         ObjectOutputStream os=new ObjectOutputStream(bos);
         os.writeObject(list);
         os.flush();
         os.close();
         byte[] b=bos.toByteArray();
         System.out.println("list的jdk序列化长度:"+b.length);

         MessagePack msgpack=new MessagePack();
         byte[] bytes=msgpack.write(list);//序列化编码
         System.out.println("list的msgpack序列化长度:"+bytes.length);

         List<String> dst=msgpack.read(bytes,Templates.tList(Templates.TString));//反序列化
         System.out.println("反序列化获取的值:"+dst.get(0));

         Teacher t=new Teacher();
         t.setNo(1);
         t.setName("张三");
         t.setSex("男");
         MessagePack msgpack1=new MessagePack();
         byte[] bytes1=MessagePack.pack(t);//序列化编码
         System.out.println("teacher序列化长度:"+bytes1.length);

         Teacher t1=msgpack1.read(bytes1, Teacher.class);
         System.out.println("t1的值:"+t1.getName());
     }
 }

运行结果集:

list的jdk序列化长度:70
list的msgpack序列化长度:7
反序列化获取的值:a
teacher序列化长度:13
t1的值:张三

显然msgpack的序列化比jdk序列化要好一点.
