Spring整合Spring Session,用redis解决分布式session共享问题

1.添加maven依赖

 <!-- spring-sesssion+redis:解决session共享问题 -->
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>1.6.4.RELEASE</version>
</dependency>
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.5.2</version>
</dependency>
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session</artifactId>
<version>2.0.0.BUILD-SNAPSHOT</version>
</dependency>

2.配置spring-session.xml中，然后导入到总的配置文件中

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<!--redis配置文件-->

<!--对于非web的客户端，将sessionId存储在header里-->
<!--<bean id="headerHttpSessionStrategy" class="org.springframework.session.web.http.HeaderHttpSessionStrategy"/>-->

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"/>

<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<property name="hostName" value="${redis.host}" />
<property name="port" value="${redis.port}" />
<property name="password" value="${redis.password}" />
<property name="timeout" value="${redis.timeout}" />
<property name="poolConfig" ref="jedisPoolConfig" />
<property name="usePool" value="true" />
</bean>

<bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
<property name="connectionFactory" ref="jedisConnectionFactory"/>
</bean>

<bean id="redisHttpSessionConfiguration" class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
<property name="maxInactiveIntervalInSeconds" value="18000"/>
<!-- header存储策略：默认是cookie存储sessionId
 <property name="httpSessionStrategy" ref="headerHttpSessionStrategy"/>-->
</bean>
</beans>

3.使用方法

对于原来的代码你不需要任何的更改，spring-session做的仅仅是将原来的HttpSession实现换成了一个自定义的实现，然后将这个session保存在redis中
