使用memcached-session-manager后报错?报错
按照官网的文档安装了memcached之后，把memcached-session-manager-1.9.2.jar、memcached-session-manager-tc7-1.9.2.jar、spymemcached-2.11.1.jar三个jar包放到tomcat下面之后。用的是java序列化。配置如下
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="n1:127.0.0.1:11211"
sticky="false"
requestUriIgnorePattern= ".*\.(png|gif|jpg|css|js)$"
transcoderFactoryClass="de.javakaffee.web.msm.JavaSerializationTranscoderFactory"
/>
然后一点进项目就报错，启动tomcat的时候没报错。一访问项目就报错。有没有懂的朋友帮忙看看什么原因啊。de.javakaffee.web.msm.MemcachedBackupSession.getAttributesFiltered这个类在memcached-session-manager-1.9.2.jar里面有啊，方法也有。为什么会报这个错误呢？

题主,你这个问题解决了么?
我这边也是酱紫,content里配置成<spanstyle="font-family:"font-size:13.3333px;background-color:#FFFFFF;">stickysession没问题.配置成非sticky以后,每次进项目会读写memcache,于是就会这样.
没解决呢，你试一下换jdk8试试，这个兼容性感觉太不好了2020-06-09 11:56:57赞同 展开评论 打赏
