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

三:測试文件

       recordsList = new ArrayList
      
       ();       for( int i =0 ; i<5 ; i++ )       {    	   Records records = new Records();    	   records.setPageSize(i);    	       	   recordsList.add(records);    	   cache.add("SELECT aaa FROM bbb WHERE "+i,records);       }       System.out.println("插入完毕==>");              //2获取       for( int i =0 ; i<9 ; i++ )       {    	   Records records = (Records)cache.get("SELECT aaa FROM bbb WHERE "+i);    	       	   if( null == records  )    	   {    		   System.out.println("dao层 再去查");     	   }    	   else    	   {       		   String str = records.getPageSize().toString();    		   System.out.println("从缓存中取得的集合为：" + str);    	   }       }    }}
