</dependency>
<dependency>
 <groupId>redis.clients</groupId>
 <artifactId>jedis</artifactId>
 <version>2.9.0</version>
</dependency>
<!-- session redis依赖  end -->


2.web.xml修改
在xml的前部位置（其他listner之前，加载配置文件之后）增加
    <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>




3.jdbc.properties修改
增加
redis.hostname=127.0.0.1
redis.port=6379
redis.pwd=123456


4.spring-hibernate.xml修改
增加
<!-- redis的配置 -->
<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="${redis.hostname}"/>
   <property name="port" value="${redis.port}"/>
   <property name="password" value="${redis.pwd}" />
   <property name="timeout" value="3000"/>
   <property name="usePool" value="true"/>
   <property name="poolConfig" ref="jedisPoolConfig"/>
</bean>

<!-- 为不同项目设置不同的cookie键值，避免产生host:端口部署不同项目产生覆盖cookie的问题 -->
<bean id="cookieSerializer" class="org.springframework.session.web.http.DefaultCookieSerializer" >
<property name="cookieName" value="修改成自己的项目名-cookie"></property>
</bean>
<bean id="redisHttpSessionConfiguration"
      class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
    <property name="maxInactiveIntervalInSeconds" value="1800"/>
    <property name="redisNamespace" value="修改成自己的项目名"></property>
    <property name="cookieSerializer" ref="cookieSerializer"></property>

5.security.xml修改（如果不存在，这一步可以省略）
<bean id="sessionRegistry"
class="org.springframework.security.core.session.SessionRegistryImpl" />

<constructor-arg name="sessionRepository" ref="sessionRepository"></constructor-arg>
</bean>
