本实例中包括xml、json、pb、msgpack四种的通信格式，采用http通信格式
在实例中我只采用了一个java对象,数据量较小,所以差异并不是非常的明显，但足以说明问题。
客户端压缩后的byte数组的长度与耗时
pb client length:30 cost time:61
pb client length:30 cost time:28
pb client length:30 cost time:27
pb client length:30 cost time:28
服务端解压缩耗时：
cost time:37
xml client length:116 cost time:112
xml client length:116 cost time:47
xml client length:116 cost time:39
xml client length:116 cost time:38

json client length:52 cost time:139
json client length:52 cost time:136

msgpack client length:28 cost time:334
msgpack client length:28 cost time:191
