基于kryo序列化方案的memcached-session-manager多memcached节点配置
??上次基于Java IO的序列化方案配置了memcached-session-manager，但是性能不好，现在先简单配置成基于kryo的
<Context path="/mobilemail" docBase="D:\webapp\WebRoot" reloadable="true"><Manager className= "de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes= "n1:192.168.112.1:11211,n2:192.168.112.2:11211" sticky="false" lockingMode="auto" requestUriIgnorePattern= ".*\.(png|gif|jpg|css|js)$" sessionBackupAsync= "false" sessionBackupTimeout= "0" memcachedProtocol="binary" copyCollectionsForSerialization="true" transcoderFactory customConverter="org.claros.commons.CustomKryoRegistration" /></Context>

?注意customConverter配置的com.test.serializer.CustomKryoRegistration这个类是自己写的类，是用来注册一些特殊类型的，同时自己负责对这些类型的序列化，可以放在项目里，也可以单独打个jar包，把以后遇到的所有复杂类型都在这里即可。项目里遇到的kryo没有注册到的类就是session里的java.util.concurrent.ConcurrentHashMap这个类，反序列化的时候本来可以做得更高效些，这里只是为了演示，直接用kryo自带的MapSerializer来反序列化
?
package com.test.serializer;import java.util.concurrent.ConcurrentHashMap;import com.esotericsoftware.kryo.Kryo;import com.esotericsoftware.kryo.serialize.MapSerializer;import de.javakaffee.web.msm.serializer.kryo.KryoCustomization;public class CustomKryoRegistration implements KryoCustomization {public void customize(Kryo kryo) {kryo.register(ConcurrentHashMap.class, new MapSerializer(kryo));}}?

感兴趣的同学请参见msm-kryo-serializer-1.4.0.jar注册wicket的MiniMap的流程(de.javakaffee.web.msm.serializer.kryo.WicketMiniMapRegistration里对MiniMap使用kryo-serializers-0.8.jar中的de.javakaffee.kryoserializers.wicket.MiniMapSerializer 单独处理)
要使用kryo进行序列化需额外添加kryo的jar包，我使用的是kryo-1.04，所需要的jar包在附件里。添加依赖的时候请注意不要引起jar包冲突，比较常见的是使用cglib和所依赖的asm的冲突，我的解决办法是留下kryo所需要的asm-3.3.1.jar，删去其他版本的asm，再将原先项目里的cglib换成cglib-nodep-2.2.jar。

你配置了customConverter么，这个要自己去写反序列化的类的，java.lang.ClassCastException:org.springframework.security.core.authority.GrantedAuthorityImpl cannot be cast to java.lang.Comparable，我给的例子是做个例子来演示的，你要根据你的实际情况自己处理Mar 23, 2011 6:24:35 PM de.javakaffee.web.msm.MemcachedBackupSessionManager loadFromMemcachedWARNING: Could not load session with id C9593682F286B6054292A348B27F4CE7-n1 from memcached.com.esotericsoftware.kryo.SerializationException: Unable to deserialize object of type: java.util.concurrent.ConcurrentHashMap at com.esotericsoftware.kryo.Kryo.readObject(Kryo.java:584) at com.esotericsoftware.kryo.ObjectBuffer.readObject(ObjectBuffer.java:209) at de.javakaffee.web.msm.serializer.kryo.KryoTranscoder.deserializeAttributes(KryoTranscoder.java:257) at de.javakaffee.web.msm.TranscoderService.deserializeAttributes(TranscoderService.java:157) at de.javakaffee.web.msm.TranscoderService.deserialize(TranscoderService.java:114) at de.javakaffee.web.msm.MemcachedBackupSessionManager.loadFromMemcached(MemcachedBackupSessionManager.java:929) at de.javakaffee.web.msm.MemcachedBackupSessionManager.findSession(MemcachedBackupSessionManager.java:519) at org.apache.catalina.connector.Request.isRequestedSessionIdValid(Request.java:2138) at org.apache.catalina.connector.CoyoteAdapter.parseSessionCookiesId(CoyoteAdapter.java:592) at org.apache.catalina.connector.CoyoteAdapter.postParseRequest(CoyoteAdapter.java:509) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:291) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:849) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:454) at java.lang.Thread.run(Thread.java:662)Caused by: com.esotericsoftware.kryo.SerializationException: Unable to deserialize object of type: org.springframework.security.core.context.SecurityContextImpl at com.esotericsoftware.kryo.Kryo.readClassAndObject(Kryo.java:562) at com.esotericsoftware.kryo.serialize.MapSerializer.readObjectData(MapSerializer.java:129) at com.esotericsoftware.kryo.Serializer.readObject(Serializer.java:61) at com.esotericsoftware.kryo.Kryo.readObject(Kryo.java:580) ... 14 moreCaused by: com.esotericsoftware.kryo.SerializationException: Serialization trace:authorities (com.fz.cloudsync.security.user.SecurityUser)principal (org.springframework.security.authentication.UsernamePasswordAuthenticationToken)authentication (org.springframework.security.core.context.SecurityContextImpl) at com.esotericsoftware.kryo.serialize.FieldSerializer.readObjectData(FieldSerializer.java:230) at com.esotericsoftware.kryo.serialize.ReferenceFieldSerializer.readObjectData(ReferenceFieldSerializer.java:81) at com.esotericsoftware.kryo.serialize.FieldSerializer.readObjectData(FieldSerializer.java:212) at com.esotericsoftware.kryo.serialize.ReferenceFieldSerializer.readObjectData(ReferenceFieldSerializer.java:81) at com.esotericsoftware.kryo.serialize.FieldSerializer.readObjectData(FieldSerializer.java:212) at com.esotericsoftware.kryo.serialize.ReferenceFieldSerializer.readObjectData(ReferenceFieldSerializer.java:81) at com.esotericsoftware.kryo.Kryo.readClassAndObject(Kryo.java:557) ... 17 moreCaused by: java.lang.ClassCastException: org.springframework.security.core.authority.GrantedAuthorityImpl cannot be cast to java.lang.Comparable at java.util.TreeMap.put(TreeMap.java:542) at java.util.TreeSet.add(TreeSet.java:238) at com.esotericsoftware.kryo.serialize.CollectionSerializer.readObjectData(CollectionSerializer.java:113) at com.esotericsoftware.kryo.Kryo.readClassAndObject(Kryo.java:557) at de.javakaffee.kryoserializers.UnmodifiableCollectionsSerializer.readObjectData(UnmodifiableCollectionsSerializer.java:84) at com.esotericsoftware.kryo.serialize.FieldSerializer.readObjectData(FieldSerializer.java:212) ... 23 more
