一、在pom.xml添加springsession

<!--springsession--> <dependency> <groupid>org.springframework.session</groupid> <artifactid>spring-session-data-redis</artifactid> <version>1.2.0.release</version> </dependency> |
二、确保spring是4.3.10.release版本以上

<dependency> <groupid>org.springframework</groupid> <artifactid>spring-context</artifactid> <version>4.3.10.release</version> </dependency> |
三、applicationcontext.xml文件中添加四个bean类

<bean id="redishttpsessionconfiguration" class="org.springframework.session.data.redis.config.annotation.web.http.redishttpsessionconfiguration"> <property name="maxinactiveintervalinseconds" value="180"></property> </bean> <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> <property name="port" value="6379"></property> <property name="poolconfig" ref="jedispoolconfig"></property> </bean> <bean id="defaultcookieserializer" class="org.springframework.session.web.http.defaultcookieserializer"> <property name="cookiename" value="springsession"></property> <property name="cookiepath" value="/"></property> <property name="cookiemaxage" value="3600"/> <property name="usehttponlycookie" value="true"/> <property name="domainname" value=".qs.com"/> </bean> |
这样就可以实现session共享，nginx下的tomcat集群也是这样的
原理就是：通过springsession对servlet带的session进行封装，接管session
