Msgpack0.6.12 java版简单使用总结
关于Msgpack官网上是这么说的，It's like JSON.but fast and small.
Msgpack0.6.12 java版使用总结：
依赖包：javassist-3.18.1-GA.jar，msgpack-0.6.12.jar
1.单个对象使用Msgpack
1.1 此对象必须要实现Serializable接口(java.io.Serializable)
1.2 此对象必须要使用@Message注解(org.msgpack.annotation.Message)
1.3 此对象属性中不能有用transient修饰的字段.
2.序列化List，Map(List接口)直接这么做msgpack不支持.
2.1 构建含有List,Map属性的字段对象
2.2 该有的步骤和构建单个对象使用Msgpack一样。

反序列化: User [id=1, name=name, password=null]
ArrayList使用Msgpack
