redis实现tomcat集群session共享

基于redis实现tomcat集群session共享，



准备事项：

1、Redis服务端（已安装，redis-3.2.8）官方下载地址：https://redis.io 安装步骤详见：https://redis.io/download

2、Tomcat7（已部署）

3、JDK1.7（已安装）

 

注意事项：

1、需要准备好3个jar包：

jedis-2.5.2.jar

commons-pool2-2.2.jar

tomcat-redis-session-manager-2.0.0.jar

下载地址： http://download.csdn.net/detail/gaowenhui2008/9723227

2、session中存放的需要共享对象，需要序列化（implements java.io.Serializable）

 

操作步骤：

1、将3个jar包放置在Tomcat的lib目录下

2、修改Tomcat的context.xml（conf目录下），增加相关配置：

启动相应服务进行测试即可。
