Spring Session实现分布式session的简单示例

<!-- spring session begin -->
  <dependency>
   <groupId>redis.clients</groupId>
   <artifactId>jedis</artifactId>
   <version>2.9.0</version>
  </dependency>
  <dependency>
   <groupId>org.springframework.data</groupId>
   <artifactId>spring-data-redis</artifactId>
   <version>1.5.2.RELEASE</version>
  </dependency>
  <dependency>
   <groupId>org.springframework.session</groupId>
   <artifactId>spring-session</artifactId>
   <version>1.3.1.RELEASE</version>
  </dependency>
  <!-- spring session end -->

 <!-- Spring Session begin -->
 <bean id="redisHttpSessionConfiguration"
  class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
  <property name="maxInactiveIntervalInSeconds" value="1800" />
 </bean>
 <!-- Spring Session end -->

<!-- 添加一个session代理filter,来包装Servlet的getSession,需要放在所有filter链最前面 -->
 <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>
