Memcached - Get CAS Data

Memcached gets 命令用于获取带有 CAS 令牌的值。如果 Memcached 中不存在该密钥,则它将不返回任何内容。

Syntax

Memcached gets 命令的基本语法如下所示:

get key

Example

set tutorialspoint 0 900 9
memcached
STORED
gets tutorialspoint
VALUE tutorialspoint 0 9 1
memcached
END

在此示例中,我们使用 tutorialspoint 作为密钥,并将 memcached 存储在其中,其到期时间为 900 秒。

Get CAS Data Using Java Application

若要从 Memcached 服务器获取 CAS 数据,您需要使用 Memcached gets 方法。

Example

import net.spy.memcached.MemcachedClient;
public class MemcachedJava {
   public static void main(String[] args) {

      // Connecting to Memcached server on localhost
      MemcachedClient mcc = new MemcachedClient(new
      InetSocketAddress("127.0.0.1", 11211));
      System.out.println("Connection to server sucessfully");
      System.out.println("set status:"+mcc.set("tutorialspoint", 900, "memcached").done);

      // Get value from cache
      System.out.println("Get from Cache:"+mcc.gets("tutorialspoint"));
   }
}

Output

编译并执行该程序后,您可以看到以下输出:

Connection to server successfully
set status:true
Get from Cache:{CasValue 2/memcached}
