SpringBoot2.x版本中,使用SpringSession踩的坑及解决

 <!--SpringSession依赖-->
 <dependency>
  <groupId>org.springframework.session</groupId>
  <artifactId>spring-session-core</artifactId>
 </dependency>
 <!--SpringSessionRedis依赖-->
 <dependency>
  <groupId>org.springframework.session</groupId>
  <artifactId>spring-session-data-redis</artifactId>
 </dependency>

#使用使用Redis缓存session数据
spring.session.store-type=REDIS
#Redis服务器地址
spring.redis.host=127.0.0.1
#Redis服务器端口号
spring.redis.port=6379
