Memcached的MemCachedClient设置过时时限

public void testMemcache(){
        MemcacheUtil.set("abc","abc", new Date(1*10*1000));  
        MemcacheUtil.set("bbb","bbb", new Date(System.currentTimeMillis()+8000));  
        
          //大于2000为null             
          try {
            Thread.sleep(1*8*1000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }  
                    
      System.out.println(MemcacheUtil.get("abc"));
      System.out.println(MemcacheUtil.get("bbb")); 
      try {
        Thread.sleep(1*1*1000);
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
      System.out.println(MemcacheUtil.get("abc"));
      System.out.println(MemcacheUtil.get("bbb")); 
    try {
        Thread.sleep(1*1*1000);
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    System.out.println(MemcacheUtil.get("abc"));
    System.out.println(MemcacheUtil.get("bbb"));
    }

输出结果：html
