hessian序列化

背景：

之前一篇文章介绍了java的序列化，http://blog.csdn.net/bohu83/article/details/51124079

在java的序列化里面也是介绍rpc框架时候，在远程调用中，需要把参数和返回值通过网络传输，这个使用就要用到序列化将对象转变成字节流，从一端到另一端之后再反序列化回来变成对象。作用了说了，今天在看文章的时候发现别人贴出效率对比，hessian比java的序列化高出很多。特意补充下相关知识点。

百科：Hessian是一个轻量级的remoting onhttp工具，使用简单的方法提供了RMI的功能。 相比WebService，Hessian更简单、快捷。采用的是二进制RPC协议，因为采用的是二进制协议，所以它很适合于发送二进制数据。

hessian序列化

hessian序列化比Java序列化高效很多，而且生成的字节流也要短很多。

测试的demo:客户端通过Hessian***协议序列化对象，通过Http Post方式提交到服务器端。

总结：

1、序列化对象要实现java.io.Serializable接口。

2、单文本传输没必要使用hessian，pojo适合用hessian，但是要注意序列化的规范，可能特殊类型支持的不够完善。
本文是是初步使用，背后的原理待整理。

背景：

之前一篇文章介绍了java的序列化，http://blog.csdn.net/bohu83/article/details/51124079

在java的序列化里面也是介绍rpc框架时候，在远程调用中，需要把参数和返回值通过网络传输，这个使用就要用到序列化将对象转变成字节流，从一端到另一端之后再反序列化回来变成对象。作用了说了，今天在看文章的时候发现别人贴出效率对比，hessian比java的序列化高出很多。特意补充下相关知识点。

百科：Hessian是一个轻量级的remoting onhttp工具，使用简单的方法提供了RMI的功能。 相比WebService，Hessian更简单、快捷。采用的是二进制RPC协议，因为采用的是二进制协议，所以它很适合于发送二进制数据。

hessian序列化

hessian序列化比Java序列化高效很多，而且生成的字节流也要短很多。

测试的demo:客户端通过Hessian***协议序列化对象，通过Http Post方式提交到服务器端。

总结：

1、序列化对象要实现java.io.Serializable接口。

2、单文本传输没必要使用hessian，pojo适合用hessian，但是要注意序列化的规范，可能特殊类型支持的不够完善。
本文是是初步使用，背后的原理待整理。
