Spring-Session+Redis实现session共享

标签：ram   second   comm   model   login   nec   mvc   通过   osi   

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:

/**

 */
@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";
    }
}
