本文记录了在使用Java客户端访问memcached时遇到的问题，当尝试缓存超过1MB的数据时，出现IllegalArgumentException异常。通过调整存储策略，最终解决了该问题。

今天在内网搭建memcachedb时，服务端搭建好后，用Java的客户端进行访问测试，在数据量设置为100，1000，10000时，都能正常访问，当我把数据量设置为10000条时，出现了下面的错误：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

目前正在找资料解决这个问题，记录下来作为备案，以作继续处理的笔记。

此问题已经解决，主要原因是因为我在测试时，把一个List当作一个对象存储进去，当然，这个List对象保存的是10W条经过MD5后的Hash数据，超大了。
