Memcached与Spring集成的方式（待实践）
2024-08-25 10:11:33
主要是基于这几种方式http://www.cnblogs.com/EasonJim/p/7624822.html去实现与Spring集成，而个人建议使用Xmemcached去集成好一些，因为现在官方还在更新，具体参考：https://github.com/killme2008/xmemcached/wiki/Xmemcached%20%E4%B8%AD%E6%96%87%E7%94%A8%E6%88%B7%E6%8C%87%E5%8D%97
以下方式据说第一种会报错，没测试过。
既然已经使用Spring做集成，那么依赖肯定要使用Maven。
Memcached已经过时了，如果是新项目就不应该侧重选择它，转投Redis。
