Why Spring MVC can't get session from redis - spring-mvc

Question

I use SpringSession+redis, it can save the session to redis,but I cant't get the session attribute the when i call "${sessionScope.user.name}" in jsp
this is web.xml
<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>
this is applicationContext.xml
<!-- spring data redis -->
<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<property name="hostName" value="localhost"/>
<property name="port" value="6379"></property>
<property name="password" value="123456"></property>
<property name="database" value="0"></property>
<property name="usePool" value="true"></property>
</bean>
<bean class="org.springframework.data.redis.core.RedisTemplate" id="redisTemplate">
<property name="connectionFactory" ref="jedisConnectionFactory" />
</bean>
<!-- spring session -->
<context:annotation-config/>
<bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration"/>
this is the controller:
#RequestMapping("/login")
public String login(String name, String pwd,HttpSession session){
User user=new User();
user.setName(name);
user.setPwd(pwd);
session.setAttribute("user",user);
return "forward:/success.jsp";
}
#RequestMapping("test")
public String test(HttpSession session){
//there,session.getAttribute("user")=null ???
return "forward:/test.jsp";
}
When i request the project, I can see the session has been saved in Redis
enter image description here
but when I request test.action ,It can't get the Seesion Attribute.
What's wrong?
