n tomcat 采用msm连接memcached缓存session

1,在tomcat中找到文件apache-tomcat-6.0.37\conf\context.xml 加入内部

<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"    
        memcachedNodes="n1:192.168.1.65:11211"    
        requestUriIgnorePattern=".*\.(png|gif|jpg|css|js)$"    
        sessionBackupAsync="false"    
        sessionBackupTimeout="100"    
        transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"    
        copyCollectionsForSerialization="false"  
 />

加入之后的content.xml的内容为

<?xml version='1.0' encoding='utf-8'?>

</Context>

memcachedNodes 多个节点之间可以用空格分开，如n1:localhost:11211 n2:localhost:11212

我memcached的机子是安装在192.168.1.65  而且只配置一台

把下面对应的jar包复制到apache-tomcat-6.0.37\lib即可

msm要用的包有：

javolution-5.4.3.1.jar
 memcached-2.5.jar
 memcached-session-manager-1.3.0.jar
 msm-javolution-serializer-1.3.0.jar
 msm-javolution-serializer-cglib-1.3.0.jar
 msm-javolution-serializer-jodatime-1.3.0.jar

我打包成一个jar包供大家下载
