Spring-Session+Redis实现session共享

1、添加依赖

<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>

2、配置

spring-mvc.xml:

<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="${redis_hostname}"/> <property name="port" value="${redis_port}"/> <property name="password" value="${redis_pwd}" /> <property name="timeout" value="3000"/> <property name="usePool" value="true"/> <property name="poolConfig" ref="jedisPoolConfig"/> </bean>

web.xml添加拦截器：

<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、使用spring-session

只要使用标准的servlet api调用session，在底层就会通过Spring Session得到的，并且会存储到Redis或其他你所选择的数据源中。

这里是我写的一个demo:

/** * @author fengzp * @date 17/2/23下午3:19 * @email [e-mail] * @company 广州易站通计算机科技有限公司 */ @Controller @RequestMapping(value = "index") public class IndexController { private final Gson gson = new GsonBuilder().setDateFormat("yyyyMMddHHmmss").create(); @RequestMapping(value = "login") public String login(HttpServletRequest request, String username){ request.getSession().setAttribute("user", gson.toJson(new User(username,"123456"))); return "login"; } @RequestMapping(value = "index") public String index(HttpServletRequest request, Model model){ User user = gson.fromJson(request.getSession().getAttribute("user").toString(), User.class); model.addAttribute("user", user); return "index"; } }
