1.引入架包

<dependency>
           <groupId>org.springframework.session</groupId>
           <artifactId>spring-session-data-redis</artifactId>
           <version>1.2.1.RELEASE</version>
       </dependency>
       <dependency>
           <groupId>redis.clients</groupId>
           <artifactId>jedis</artifactId>
           <version>2.8.1</version>
       </dependency>

2.spring.xml配置连接redis

<bean id="redisHttpSessionConfiguration"
      class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
    
    <property name="maxInactiveIntervalInSeconds" value="600"/>
</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="127.0.0.1"/>
    <property name="port" value="6379"/>
//安装redis默认不需要密码认证，如果开启了密码认证，这里必须加上
    <property name="timeout" value="3000"/>
    <property name="usePool" value="true"/>
    <property name="poolConfig" ref="jedisPoolConfig"/>
</bean>

3.web.xml配置

<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>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>ERROR</dispatcher>
</filter-mapping>

注意：这个过滤器配置最好放在其他过滤器的前面，具体原因不详，但我曾因为这个问题苦找了几天，阴差阳错这才解决。
