 1.memcached client for java

 

1. import  com.danga.MemCached.*;  
2. import  org.apache.log4j.*;  
3. public   class  TestMemcached {  
4.     public   static   void  main(String[] args) {  
5.         /*初始化SockIOPool，管理memcached的连接池*/   
6.         String[] servers = { "192.168.1.20:12111"  };

9.         pool.setFailover(true );  
10.         pool.setInitConn(10 );  
11.         pool.setMinConn(5 );  
12.         pool.setMaxConn(250 );

17.         pool.initialize();  
18.         /*建立MemcachedClient实例*/   
19.         MemCachedClient memCachedClient = new  MemCachedClient();  
20.         for  ( int  i =  0 ; i <  10 ; i++) {  
21.             /*将对象加入到memcached缓存*/   
22.             boolean  success = memCachedClient.set( ""  + i,  "Hello!" );  
23.             /*从memcached缓存中按key值取对象*/   
24.             String result = (String) memCachedClient.get(""  + i);  
25.             System.out.println(String.format("set( %d ): %s" , i, success));  
26.             System.out.println(String.format("get( %d ): %s" , i, result));  
27.         }  
28.     }

用spymemcached将对象存入缓存

1. import  java.net.InetSocketAddress;  
2. import  java.util.concurrent.Future;  
3.   
4. import  net.spy.memcached.MemcachedClient;  
5.   
6. public   class  MClient {  
7.   
8.     public   static   void  main(String[] args){  
9.         try {  
10.             /*建立MemcachedClient 实例，并指定memcached服务的IP地址和端口号*/   
11.             MemcachedClient mc = new  MemcachedClient( new  InetSocketAddress( "192.168.1.20" ,  12111 ));  
12.             Future<Boolean> b = null ;  
13.             /*将key值，过期时间(秒)和要缓存的对象set到memcached中*/   
14.             b = mc.set("neea:testDaF:ksIdno" ,  900 ,  "someObject" );  
15.             if (b.get().booleanValue()== true ){  
16.                 mc.shutdown();  
17.             }  
18.         }  
19.         catch (Exception ex){  
20.             ex.printStackTrace();  
21.         }  
22.     }  
23. }
