要连接到Memcached服务器,您需要在主机名和端口名上使用telnet命令。
Memcached telnet命令的基本语法如下所示-
$telnet HOST PORT
在这里, HOST和PORT分别是正在执行Memcached服务器的计算机IP和端口号。
以下示例显示了如何连接到Memcached服务器并执行简单的set and get命令。假定Memcached服务器正在主机127.0.0.1和端口11211上运行。
$telnet 127.0.0.1 11211
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
// now store some data and get it from memcached server
set tutorialspoint 0 900 9
memcached
STORED
get tutorialspoint
VALUE tutorialspoint 0 9
memcached
END
要从Java程序连接Memcached服务器,您需要将Memcached jar添加到您的类路径中,如上一章所示。假定Memcached服务器正在主机127.0.0.1和端口11211上运行。-
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");
//not set data into memcached server
System.out.println("set status:"+mcc.set("tutorialspoint", 900, "memcached").done);
//Get value from cache
System.out.println("Get from Cache:"+mcc.get("tutorialspoint"));
}
}
在编译和执行程序时,您将看到以下输出-
Connection to server successfully
set status:true
Get from Cache:memcached.
终端也可能只显示很少的参考消息,这些消息可以忽略。
