Tomcat使用redis管理session

server.xml

<!-- GlobalNamingResources节点中添加新的Resource节点 -->
    <GlobalNamingResources>
    <!-- Editable user database that can also be used by
         UserDatabaseRealm to authenticate users
    -->
        <Resource auth="Container" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" name="UserDatabase" pathname="conf/tomcat-users.xml" type="org.apache.catalina.UserDatabase"/>
	    <!-- tomcat session 共享 -->
        <Resource auth="Container" closeMethod="shutdown" 
			    configPath="${catalina.base}/conf/redisson.yaml" 
			    factory="org.redisson.JndiRedissonFactory" 
			    name="bean/redisson"
			    />
    </GlobalNamingResources>

</Context>

在server.xml,context.xml同级目录里面，也就是/tomcat/conf/目录内，添加文件redisson.yaml

其中password，address按照系统配置书写

singleServerConfig:
  idleConnectionTimeout: 10000
  connectTimeout: 10000
  timeout: 3000
  retryAttempts: 3
  retryInterval: 1500
  password: xxxxxx

  subscriptionConnectionPoolSize: 50
  connectionMinimumIdleSize: 24
  connectionPoolSize: 64
  database: 0
  dnsMonitoringInterval: 5000
