Memcached与Spring集成的方式(待实践)

标签:nagle   3.2   .config   enc   before   ref   git   操作   初始化   

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。
