使用Redis保存Spring session(基于XML配置文件)

Spring session是一种分布式session共享方案，提供了管理用户session信息的接口及实现。下文描述如何通过XML配置文件的方式实现使用Redis保存Spring session。

前置条件：Redis server已安装就绪。

(1) pom.xml配置(下载依赖包)

...
<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>
...

(2) application.properties配置(保存redis server信息及redis连接池参数)

#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

(3) applicationContext.xml配置(bean配置)

<!-- 属性文件位置 -->
<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>
