memcached的使用

http://sacharya.com/using-memcached-with-java/

参看这里，然后将两个jar包下载下来

java_memcached-release_2.5.0中有比较详细文档，看起来也还比较清晰易懂

例如下面这个，我也仅是目前简单用了下这个，没有使用太多别东西

import com.danga.MemCached.MemCachedClient;
import com.danga.MemCached.SockIOPool;

An example of initializing using defaults:

 static {
　　String[] serverlist = { "server1.com:port", "server2.com:port" };
　　SockIOPool pool = SockIOPool.getInstance();
　　pool.setServers(serverlist);
　　pool.initialize(); 
} 

Then we can create the client object.

To create cache client object:

 MemCachedClient mc = new MemCachedClient(); 

To store an object:

 MemCachedClient mc = new MemCachedClient(); 
 String key = "cacheKey1";
 Object value = SomeClass.getObject(); mc.set(key, value); 

To delete a cache entry:

 MemCachedClient mc = new MemCachedClient();
 String key = "cacheKey1"; mc.delete(key); 

To retrieve an object from the cache:

 MemCachedClient mc = new MemCachedClient();
 String key = "key"; Object value = mc.get(key); 

To retrieve an multiple objects from the cache

 MemCachedClient mc = new MemCachedClient();
 String[] keys = { "key", "key1", "key2" }; 
 Map<Object> values = mc.getMulti(keys); 

To flush all items in server(s)

 MemCachedClient mc = new MemCachedClient();
 mc.flushAll();
