Memcached - Clear Data
Memcached flush_all 命令用于从 Memcached 服务器删除所有数据(键值对)。它接受一个名为 time 的可选参数,该参数设置一个时间,在此时间之后将清除 Memcached 数据。
Clear Data Using Java Application
要从 Memcached 服务器清除数据,你需要使用 Memcached flush 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("count", 900, "5").isDone());
// Get value from cache
System.out.println("Get from Cache:"+mcc.get("count"));
// now increase the stored value
System.out.println("Increment value:"+mcc.incr("count", 2));
// now decrease the stored value
System.out.println("Decrement value:"+mcc.decr("count", 1));
// now get the final stored value
System.out.println("Get from Cache:"+mcc.get("count"));
// now clear all this data
System.out.println("Clear data:"+mcc.flush().isDone());
}
}
