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.

 1 package com.ming.netty.code;

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

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;

 3 import java.io.ByteArrayOutputStream;
 4 import java.io.ObjectOutputStream;
 5 import java.util.ArrayList;
 6 import java.util.List;

 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<String> 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<String> 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: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.
