How to store memcache objects

Memchache serializes the object, saves memcahce, serializes the value into a byte array, and stores it in the cache. In the following example, the userobject is sequentially converted to the.txt file, and the user is saved to the cache. By comparing the values in the file and cache, we can find that the two are the same. PublicclassUserimplementsSerializable {priv

Memchache serializes the object and saves it

Memcahce serializes values into byte arrays and stores them in the cache.

In the following example, the userobject is sequentially converted to the.txt file, and the user is saved to the cache by comparing the values in the file and cache.
The two are the same.

public class User implements Serializable{    private String name;    private String address;    public User(String name, String address) {        super();        this.name = name;        this.address = address;    }}

Public static void main (String [] args) throws InterruptedException, ExecutionException, FileNotFoundException, IOException {MemcachedClient mcc = null; try {// locally connect to the Memcached service mcc = new MemcachedClient (new InetSocketAddress ("127.0.0.1", 11211); System. out. println ("Connection to server sucessful. ");} catch (Exception ex) {System. out. println (ex. getMessage ();} User u = new User ("junwang", "qingdao city "); objectOutputStream oos = new ObjectOutputStream (new FileOutputStream (new File ("a.txt"); oos. writeObject (u); Future fo = mcc. set ("myuser", 5*60*1000, u); // view the storage status System. out. println ("set status:" + fo. get (); // output value System. out. println ("myuser value in cache-" + mcc. get ("myuser"); // close the connection to mcc. shutdown ();}

View Source Code

View the source code and find that the object is serialized and then saved. Proves our above conjecture.

Conclusion

The stored values are serialized into byte arrays and then saved.
