查看redis是否可用

redis-cli -h 192.168.1.103 -p 6379
    auth 123456
    keys *

9) "spring:session:sessions:expires:c1295cf3-e0f7-4f01-8c31-fe85dab6517b"

默认request header：

Cookie:

SESSION=531b91bc-df97-42c4-91cc-3a29ef5d7c15

如果我们有两套不同的子系统A和B，cookies中session名称相同会导致同一个浏览器登录两个系统会造成相互的干扰；

1，不同系统的redis空间不同

2，不同系统的cookie的key不同

@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 7200,redisNamespace="nick")
    public class RedisHttpSessionConfig {
    
        @Bean
        public RedisConnectionFactory connectionFactory() {
    
            JedisConnectionFactory connectionFactory = new JedisConnectionFactory();
            connectionFactory.setPort(6379);
            connectionFactory.setHostName("***");
            connectionFactory.setPassword("***");
            return connectionFactory;
        }
    
        /*@Bean
        不要使用这个
        public HttpSessionStrategy httpSessionStrategy() {
            return new HeaderHttpSessionStrategy();
        }*/
    
        @Bean
        public CookieHttpSessionStrategy cookieHttpSessionStrategy(){
            CookieHttpSessionStrategy strategy=new CookieHttpSessionStrategy();
            DefaultCookieSerializer cookieSerializer=new DefaultCookieSerializer();
            cookieSerializer.setCookieName("NICKSESSIONID");//cookies名称
            cookieSerializer.setCookieMaxAge(1800);//过期时间(秒)
            strategy.setCookieSerializer(cookieSerializer);
            return strategy;
        }
    
    }
