HDC调试需求开发（15万预算）,能者速来！>>>
在解决nginx+tomcat+memcached集群session的问题中，我在本机(Windows)测试，nginx+2个tomcat，将memcached添加到系统服务中并启动，分别添加memcached的jar包到tomcat的lib中，配置两个tomcat的context.xml，启动两个tomcat，访问页面报错，起初以为是版本的问题，换了好多版本的jar包，问题依旧，求高人指点。
context.xml配置如下： <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="n1:127.0.0.1:11211" requestUriIgnorePattern=".*/.(png|gif|jpg|css|js)$" sessionBackupAsync="false" sessionBackupTimeout="100" transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory" copyCollectionsForSerialization="false" />
错误信息如下： java.lang.NoSuchMethodError: net.spy.memcached.MemcachedClient.set(Ljava/lang/String;ILjava/lang/Object;)Lnet/spy/memcached/internal/OperationFuture; at de.javakaffee.web.msm.BackupSessionTask.storeSessionInMemcached(BackupSessionTask.java:227) at de.javakaffee.web.msm.BackupSessionTask.doBackupSession(BackupSessionTask.java:194) at de.javakaffee.web.msm.BackupSessionTask.call(BackupSessionTask.java:119) at de.javakaffee.web.msm.BackupSessionTask.call(BackupSessionTask.java:50) at de.javakaffee.web.msm.BackupSessionService$SynchronousExecutorService.submit(BackupSessionService.java:346) at de.javakaffee.web.msm.BackupSessionService.backupSession(BackupSessionService.java:205) at de.javakaffee.web.msm.MemcachedSessionService.backupSession(MemcachedSessionService.java:1059) at de.javakaffee.web.msm.RequestTrackingHostValve.backupSession(RequestTrackingHostValve.java:229) at de.javakaffee.web.msm.RequestTrackingHostValve.invoke(RequestTrackingHostValve.java:154) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:104) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:261) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:581) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:619)
