Spring session是一種分散式session共享方案，提供了管理使用者session資訊的介面及實現。下文描述如何通過XML配置檔案的方式實現使用Redis儲存Spring session。

前置條件：Redis server已安裝就緒。

(1) pom.xml配置(下載依賴包)

...
<dependencies>
	...
	<dependency>
		<groupId>org.springframework.session</groupId>
		<artifactId>spring-session-data-redis</artifactId>
		<version>1.2.0.RELEASE</version>
	</dependency>
	...
</dependencies>
... 
<repositories>
	...
	<repository>
		<id>spring-snapshot</id>
		<url>https://repo.spring.io/libs-snapshot</url>
	</repository>
	...
</repositories>
...
 

#redis config
redis.host=192.168.1.100
redis.port=6379
redis.pass=lWnxl2SbwOS0QXEMi05d1fvK1aBevtRF
redis.db=0
redis.maxIdle=300
redis.maxActive=600
redis.maxWait=1000
redis.testOnBorrow=true

<!-- 屬性檔案位置 -->
<context:property-placeholder location="classpath:application.properties" />
...
<context:annotation-config/>
<bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration"/>

<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
	<property name="maxIdle" value="${redis.maxIdle}" />
	<property name="maxTotal" value="${redis.maxActive}" />
	<property name="maxWaitMillis" value="${redis.maxWait}" />
	<property name="testOnBorrow" value="${redis.testOnBorrow}" />
</bean>

<bean class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
	p:host-name="${redis.host}" p:port="${redis.port}" p:password="${redis.pass}" p:database="${redis.db}" p:pool-config-ref="poolConfig"/>
 

(4) web.xml配置(filter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> 
</filter-mapping>
