tomcat集群Spring-Session+Redis实现session共享

一、Jar包引用
我们目前使用的spring版本是如下

org.springframework.version----4.3.15.RELEASE

<dependency>
   <groupId>org.springframework.session</groupId>
   <artifactId>spring-session-data-redis</artifactId>
   <version>1.2.1.RELEASE</version>
</dependency>

spring-mvc.xml配置

<!--tomcat集群配置信息-->
<bean name="redisHttpSessionConfiguration" class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
<!--maxInactiveIntervalInSeconds   以秒为单位-->
   <property name="maxInactiveIntervalInSeconds" value="10"/>
</bean>
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
   <property name="maxTotal" value="100" />
   <property name="maxIdle" value="10" />
</bean>
<bean id="jedisConnectionFactory"
     class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" destroy-method="destroy">
   <property name="hostName" value="localhost"/>
   <property name="port" value="9763"/>
   <property name="timeout" value="3000"/>
   <property name="usePool" value="true"/>
   <property name="poolConfig" ref="jedisPoolConfig"/>
</bean>

增加redis集群配置方式

把以下内容配置到jedisConnectionFactory节点中去, 屏蔽单一节点配置方式
<!--集群配置-->
		<!--<constructor-arg ref="redisClusterConfiguration" />-->
<!--集群使用-->
	<bean id="redisClusterConfiguration"
		  class="org.springframework.data.redis.connection.RedisClusterConfiguration">
		<property name="maxRedirects" value="3"></property>
		<!-- 节点配置 -->
		<property name="clusterNodes">
			<set>
				<!--<bean class="org.springframework.data.redis.connection.RedisClusterNode">-->
					<!--<constructor-arg name="host" value="10.45.59.201"></constructor-arg>-->
					<!--<constructor-arg name="port" value="7670"></constructor-arg>-->
				<!--</bean>-->
				<bean class="org.springframework.data.redis.connection.RedisClusterNode">
					<constructor-arg name="host" value="10.45.59.202"></constructor-arg>
					<constructor-arg name="port" value="7670"></constructor-arg>
				</bean>
			</set>
		</property>
	</bean>

web.xml添加拦截器

<filter>
    <filter-name>springSessionRepositoryFilter</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
    <filter-name>springSessionRepositoryFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
