开工开工,
准备条件:
1. 本地Redis,官网:http://redis.io/,windows下
https://github.com/ServiceStack/redis-windows
https://github.com/MSOpenTech/redis/releases msi版本
2. Maven下的项目
开始:
1. 依赖配置pom.xml
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session</artifactId>
<version>1.0.1.RELEASE</version>
</dependency>
<dependency>
<groupId>com.orange.redis-embedded</groupId>
<artifactId>embedded-redis</artifactId>
<version>0.6</version>
</dependency>
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session-data-redis</artifactId>
<version>1.0.1.RELEASE</version>
</dependency>
2. web.xml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>
3.SpringMVC.xml配置
<!-- spring session redis 配置 -->
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"/>
<!--Redis 单机配置 -->
<!--
<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="${redis.password}" />-->
<!--<property name="timeout" value="${redis.timeout}" />-->
<!--<property name="poolConfig" ref="jedisPoolConfig" /> -->
<!--<property name="usePool" value="true" /> -->
<!-- </bean> -->
<!-- Redis 集群配置 -->
<!--
<bean id="sentinelConfig" class="org.springframework.data.redis.connection.RedisSentinelConfiguration">
<constructor-arg name="master" value="mymaster" />
<constructor-arg name="sentinelHostAndPorts">
<set>
<value>xxx.xx.x.xxx:xxxxx</value>
<value>xxx.xx.x.xxx:xxxxx</value>
<value>xxx.xx.x.xxx:xxxxx</value>
</set>
</constructor-arg>
</bean>
<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<constructor-arg ref="sentinelConfig" />
</bean> -->
<!--
<bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
<property name="connectionFactory" ref="jedisConnectionFactory" />
</bean> -->
<!-- 将session放入redis 360分钟-->
<!--
<bean id="redisHttpSessionConfiguration"
class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
<property name="maxInactiveIntervalInSeconds" value="21600" />
</bean> -->
就着完了,注意看集群配置,因为我是本地没有测试到集群。
这是第一种配置方式,第二种配置,上面的所有配置都不需要,除了pom的依赖文件。
第二种配置,添加两个类文件,什么都不用做了,ok.
@EnableRedisHttpSession
public class SessionConfig {
@Bean
public JedisConnectionFactory connectionFactory() {
JedisConnectionFactory connection = new JedisConnectionFactory();
connection.setPort(6379);
connection.setHostName("127.0.0.1");
return connection;
}
}
public class SessionInitializer extends AbstractHttpSessionApplicationInitializer
{
public SessionInitializer()
{
super(SessionConfig.class);
}
}
测试session,你打开你的网站,用浏览器,
打开 redis-cli.exe,执行 keys *,你就可以看到当前所有的keys值,
再打开一个浏览器,再执行 keys *,你会发现多了两个key,一个是记住过期的事件,
你可以打开 浏览器,F12,执行js new Date(value),把你的value贴进去,就知道是什么时候过期了。

使用spring-session把http session放到redis里面

如何在Redis中查看Session数据?
(1)Http Session数据在Redis中是以Hash结构存储的。
(2)可以看到,还有一个key="spring:session:expirations:1431577740000"的数据,是以Set结构保存的。这个值记录了所有session数据应该被删除的时间(即最新的一个session数据过期的时间)。
