Spring Integrated memcached Three ways (i)

Reprint: http://blog.csdn.net/u013725455/article/details/52102170

Memcached client currently has 3 types:
Memcached Client for Java
Spymemcached
Xmemcached

These three types of clients have been controversial:
Memcached Client for Java is more stable, earlier and wider than spymemcached;
Spymemcached is more efficient than Memcached Client for Java;
Xmemcached is more effective than spymemcache concurrency.

Mode one: Memcached Client for Java
Jar Pack Preparation: Java_memcached-release_2.6.6.jar

Memcached.properties configuration file: Configure server address, number of connections, time-out, etc.

System.out.println ("AA", "BB", New Date (Memcachedutils.set)); Object obj = Memcachedutils.get ("AA");  System.out.println ("***************************");  System.out.println (Obj.tostring ());
