Spring集成Memcached三种方式

2017-06-09 13:17 477 查看
Memcached Client目前有3种：

Memcached Client for
Java

SpyMemcached

XMemcached

这三种Client一直存在各种争议：

Memcached Client for Java 比 SpyMemcached更稳定、更早、更广泛；

SpyMemcached 比 Memcached Client for Java更高效；

XMemcached 比 SpyMemcache并发效果更好。

方式一：Memcached Client for Java

jar包准备：java_memcached-release_2.6.6.jar
