java + memcached安装
一:安装
(临时获取上手windows实验)
1.下载memcached.exe , 上F:\memcached\ 下
2.在CMD在输入 "F:\memcached\memcached.exe -d install" 安装.
3.再输入:"F:\memcached\memcached.exe -d start" 启动。以后memcached将作为windows的一个服务每次开机时自己主动启动。
这样server端已经安装完成了。
二:java引包
下面的包都是网上找的, 传说是阿里某高人封的
alisoft-xplatform-asf-cache-2.5.1.jar
hessian-3.0.1.jar
stax-api-1.0.1.jar
wstx-asl-2.0.2.jar
