springsession使用redis

首先通过maven或gradle加载相关依赖

<!--spring session-->
<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session</artifactId>
    <version>1.3.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-redis</artifactId>
    <version>1.7.6.RELEASE</version>
</dependency>
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version>
</dependency>

配置servlet容器

<!--spring session-->
<!--必须是第一个-->
<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>

springsession本质上是通过filter来处理session的

配置spring

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
</bean>
<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
    <property name="hostName" value="127.0.0.1" />
    <property name="port" value="6379" />
    <property name="password" value="" />
    <property name="timeout" value="1800" />
    <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="30" />
</bean>

访问浏览器

看到JSESSIONID变成了SESSION

在redis查看key，可以看到相关数据。
