Spring session共享问题 将session放入redis(转)
将session放入放入redis缓存中可以解决多个应用session共享问题
一、主要pom依赖
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session-data-redis</artifactId>
<version>1.2.1.RELEASE</version>
</dependency>
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.8.1</version>
</dependency>
二、spring配置
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxTotal" value="30"/>
<property name="maxIdle" value="10"/>
<property name="minIdle" value="1"/>
<property name="maxWaitMillis" value="30000"/>
<property name="testOnBorrow" value="true"/>
<property name="testOnReturn" value="false"/>
<property name="testWhileIdle" value="false"/>
</bean>
<context:annotation-config/>
<!-- 把session放入redis -->
<bean id="redisHttpSessionConfiguration"
class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
<property name="maxInactiveIntervalInSeconds" value="1800"/>
</bean>
<!-- redis连接池 -->
<bean id="jedisConnectionFactory"
class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" destroy-method="destroy">
<property name="hostName" value="127.0.0.1"/>
<property name="port" value="6379"/>
<property name="password" value="yourpass" />
<property name="timeout" value="3000"/>
<property name="usePool" value="true"/>
<property name="poolConfig" ref="jedisPoolConfig"/>
</bean>
<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
<property name="connectionFactory" ref="jedisConnectionFactory"/>
</bean>
三、web.xml配置fiter和session生命周期
<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>
<session-config>
<session-timeout>30</session-timeout>
</session-config>
四、使用及验证结果
直接使用 request.getSession().setAttribute("springtest","test"); 就把session放入缓存中了
在redis中查看key
