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.

 

1 package com.ming.netty.code; 2  3 import java.io.Serializable; 4 import java.nio.ByteBuffer; 5  6  7 /** 8  * 一个普通学生类 9  * @author mingge10  *11  */12 public class Student implements Serializable{13     private static final long serialVersionUID = 1L;14 15     private String stuName;16 17 18     public String getStuName() {19         return stuName;20     }21 22     public void setStuName(String stuName) {23         this.stuName = stuName;24     }25     26     public byte[] codeC(){27         ByteBuffer buffer=ByteBuffer.allocate(1024);28         byte[] value=this.getStuName().getBytes();29         buffer.putInt(value.length);30         buffer.put(value);31         buffer.flip();32         value=null;33         byte[] result=new byte[buffer.remaining()];34         buffer.get(result);35         return result;36     }37     38 }

1 package com.ming.netty.code; 2  3 import java.io.ByteArrayOutputStream; 4 import java.io.ObjectOutputStream; 5 import java.util.ArrayList; 6 import java.util.List; 7  8 import org.msgpack.MessagePack; 9 import org.msgpack.template.Templates;10 11 public class TestMsgPack {12 13     public static void main(String[] args) throws Exception{14         List
     
       list=new ArrayList<>();15         list.add("a");16         list.add("b");17         list.add("c");18         19         ByteArrayOutputStream bos=new ByteArrayOutputStream();20         ObjectOutputStream os=new ObjectOutputStream(bos);21         os.writeObject(list);22         os.flush();23         os.close();24         byte[] b=bos.toByteArray();25         System.out.println("list的jdk序列化长度:"+b.length);26         27         MessagePack msgpack=new MessagePack();28         byte[] bytes=msgpack.write(list);//序列化编码29         System.out.println("list的msgpack序列化长度:"+bytes.length);30         31         List
      
        dst=msgpack.read(bytes,Templates.tList(Templates.TString));//反序列化32         System.out.println("反序列化获取的值:"+dst.get(0));33         34         Teacher t=new Teacher();35         t.setNo(1);36         t.setName("张三");37         t.setSex("男");38         MessagePack msgpack1=new MessagePack();39         byte[] bytes1=MessagePack.pack(t);//序列化编码40         System.out.println("teacher序列化长度:"+bytes1.length);41         42         43         44         Teacher t1=msgpack1.read(bytes1, Teacher.class);45         System.out.println("t1的值:"+t1.getName());46     }47 }
      
     

运行结果集:

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

显然msgpack的序列化比jdk序列化要好一点.
