Spring-Session+Redis實現session共用

標籤：ram   second   comm   model   login   nec   mvc   通過   osi   

1、添加依賴

<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添加攔截器：

<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

只要使用標準的servlet api調用session，在底層就會通過Spring Session得到的，並且會儲存到Redis或其他你所選擇的資料來源中。

這裡是我寫的一個demo:

/** * @author fengzp * @date 17/2/23下午3:19 * @email [email protected] * @company 廣州易站通電腦科技有限公司 */@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";    }}
