用Redis管理Session
maven
<dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.8.1</version> </dependency> <dependency> <groupId>org.springframework.session</groupId> <artifactId>spring-session-data-redis</artifactId> <version>1.3.1.RELEASE</version> <type>pom</type> </dependency>
web.xml
FIlter最好不要用别的名字
<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>
Spirng配置文件
<!--redis与session --> <bean id="redisHttpSessionConfiguration" class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration"> <property name="maxInactiveIntervalInSeconds" value="600"/> </bean> <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxTotal" value="100" /> <property name="maxIdle" value="10" /> </bean> <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" destroy-method="destroy"> <property name="hostName" value="localhost"/> <property name="port" value="6379"/> <property name="timeout" value="3000"/> <property name="usePool" value="true"/> <property name="poolConfig" ref="jedisPoolConfig"/> </bean>
注意把Bean的位置,这些Bean不能写到SpringMVC的配置文件里,因为对Session的管理是Spring父容器来完成的,SpringMVC是Spring容器的子容器,父容器看不到子容器的Bean。要么直接写到Spring容器里,要么写到一个单独的XML配置文件里然后Import进Spring容器里。否则会抛出org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'springSessionRepositoryFilter' is defined异常。配置的Filter是一个代理对象,他需要一个真正的对象来完成Session管理,真正对象就抛出异常里没有找到的异常。默认情况下去Spring容器里找该真正工作Bean,所以务必要在Spring容器里配出该Bean。
