1.引入jar包

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
    <version>x.x.x</version>
</dependency>

2.配置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>

2.配置spring文件

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

    <!-- cookie相关配置 -->
    <bean id="defaultCookieSerializer" class="org.springframework.session.web.http.DefaultCookieSerializer">
        <property name="domainName" value="localhost" />
        <property name="useHttpOnlyCookie" value="true" />
        <property name="cookiePath" value="/" />
        <property name="cookieMaxAge" value="1800" />
    </bean>

    <!-- 配置redis连接池 -->
    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxTotal" value="20"/>
    </bean>

    <!-- 配置jedis连接工厂，用于连接redis -->
    <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="hostName" value="127.0.0.1" />
        <property name="port" value="6379" />
        <property name="poolConfig" ref="jedisPoolConfig" />
    </bean>

3.编写方法

    @RequestMapping(value = "login",method = RequestMethod.GET)
    @ResponseBody
    public String login(HttpSession session)  {
        JSONObject object = new JSONObject();
        object.put("name","'zhangsan'");
        object.put("pwd",123);
        session.setAttribute("user",object);
       return "Tomcat1登录成功";
    }
    
    @RequestMapping(value = "getUserInfo",method = RequestMethod.GET)
    @ResponseBody
    public String getUserInfo(HttpSession session)   {
         Object user = session.getAttribute("user");
        if (user==null){
            return "请重新登录!";
        }
        JSONObject object = JSONObject.parseObject(user.toString());
        object.put("server","Tomcat1");
        return object.toJSONString();
    }

    @RequestMapping(value = "logout",method = RequestMethod.GET)
    @ResponseBody
    public String logout(HttpSession session)   {
        session.removeAttribute("user");
      return "Tomcat1注销成功";
    }
