在redis中存入同样的压缩数据，取操作执行两个操作：
1 从redis中取
2 解压
3 统一json压缩后放出
ab测试:
[yejianfeng@openstack ~/httpd/usr/bin]$ ./ab -n 10000 -c 10 'http://10.16.15.118:7701/location/testGet?type=json'
Requests per second: 265.11 [#/sec] (mean)

压缩比例：
[yejianfeng@test34x-nova /tmp]$ ll -h test*
-rw-r--r-- 1 server server 29K Jan 3 21:40 testjson
-rw-r--r-- 1 server server 22K Jan 3 21:40 testmsgpack
-rw-r--r-- 1 server server 31K Jan 3 21:40 testserialize
[yejianfeng@test34x-nova /tmp]$ ll test*
-rw-r--r-- 1 server server 28942 Jan 3 21:40 testjson
-rw-r--r-- 1 server server 21993 Jan 3 21:40 testmsgpack
-rw-r--r-- 1 server server 31537 Jan 3 21:40 testserialize
msgpack是serizalize的69%
json是serizalize的91.8%
