使用memcached-session-manager后报错

Question

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？

Answer 1

没解决呢，你试一下换jdk8试试，这个兼容性感觉太不好了

Answer 2

题主,你这个问题解决了么?

我这边也是酱紫, content里配置成sticky session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.

Answer 3

这些包也是放tomcat的lib就行了吗

Answer 4

回复：
@仁江 是的

Answer 5

回复
能把你的jar包发我一下吗。我用的是tomcat7，jdk7.我感觉是不是这些jar包的版本有问题。我把那些jar包都加进去之后运行总是报错

Answer 6

回复
兄弟，你这个问题解决了吗

Answer 7

回复
没解决，不知道是不是和我用的jdk或者tomcat版本有关。最后用了nginx_upstream_jvm_route模板解决了

Answer 8

jar包没加全，我也用的这个同步session 但是比你多了好几个jar, 回复 @仁江 : asm-3.2.jar、kryo-1.04.jar、kryo-serializers-0.11.jar、minlog-1.2.jar、msm-kryo-serializer-1.8.2.jar、reflectasm-1.01.jar还差这几个
