1、网上查找资料，大部分从下面网址下载java代码，因是几年前实现的（大概2,3年前吧），不支持tomcat8
https://github.com/jcoleman/tomcat-redis-session-manager
2、在myeclipse 新建一个maven项目【maven-archetype-quickstart】
源文件新建包名com.orangefunction.tomcat.redissessions
讲下载下来的java类拷贝到该包之下（这些java类只实现tomcat7，实现tomcat8需要做一些修改）
JavaSerializer.java
RedisSession.java
RedisSessionHandlerValve.java
RedisSessionManager.java
Serializer.java
SessionSerializationMetadata.java

3、maven设置
====tomcat8 maven pom.xml====
<dependencies> <dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-catalina</artifactId> <version>8.0.33</version> </dependency> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.7.2</version> </dependency> </dependencies> <build> <plugins> <plugin> <!-- 打jar包 --> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.0</version> <configuration> <!-- 源代码编译版本 --> <source>1.8</source> <!-- 目标平台编译版本 --> <target>1.8</target> <!-- 字符集编码 --> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </build>
将打包出来的tomcat-redis的jar包和
jedis-2.7.2.jar
commons-pool2-2.3.jar
拷贝到tomcat的lib文件夹下面
4、tomcat配置
====tomcat context.xml====
<!-- com.orangefunction.tomcat.redissessions 是自定义maven项目的报名路径，切需要与maven 中 RedisSessionManager的serializationStrategyClass值一致 --> <!-- redis session 共享配置 --> <Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" /> <Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager" host="127.0.0.1" port="6379" database="0" maxInactiveInterval="60" />
5、需要特别注意的是项目中要存入session的对象必须实现序列化，否知会出现序列化错误
public class Test implements Serializable { private static final long serialVersionUID = 5021582410009851677L; ...... }
