【问题】
同名方法(createMemcachedNode)存在于两个类中：
1> de.javakaffee.web.msm.SuffixLocatorBinaryConnectionFactory.createMemcachedNode
2>  net.spy.memcached.BinaryConnectionFactory.createMemcachedNode
If this method in BinaryConnectionFactory is called, there is no problem. If the method of SuffixLocatorBinaryConnectionFactory is called, [NoSuchMethodError]

net.spy.memcached.MemcachedConnection.createConnections call
/////////begin/////
private final ConnectionFactory connectionFactory;
MemcachedNode qa = this.connectionFactory.createMemcachedNode(sa, ch, this.bufSize);
/////////end///////
and connectionFactory has multiple implementation classes, as above (1) and (2), should use (2) without problems.
You can consider specifying its implementation class through the jvm parameter -D.
[Solution]
After comparison, it was found that the jar versions were inconsistent, and memcached-session-manager-1.8.2.jar needed to use spymemcached-2.11.1.jar instead of spymemcached-2.8.1.jar.
