在Spring框架下使用Hessian 3.2.1版本时，可能会遇到不兼容Hessian 1.0协议的问题，表现为解析错误。解决方法是客户端应明确发送协议版本标识。

hessian3.2.1工作在2.0-2.5.6spring下会出现问题哦。如果你遇到expected string at 0x6d这个错误信息那么看看这段话吧.不能百度啊，还是谷歌强些.搞了我一晚

Feature. The initial 3 bytes indicates the protocol and version. The
server needs to decode those three bytes and select the proper protocol.

Clients which need to support Hessian 1.0 servers should send "c \x02
\x00" and use Hessian 1.0 encoding. Clients which know the server is
Hessian 2.0 should send "H \x02 \x00".
