在开发中选用 spring-boot-starter-data-redis-reactive 包

            org.springframework.boot
            spring-boot-starter-data-redis-reactive
            2.0.5.RELEASE

内部引用包括了

            org.springframework.boot
            spring-boot-starter-data-redis

与

org.springframework.data
spring-data-redis
2.1.0.RELEASE

打开spring-data-redis的pom文件可以看到包括

5.0.4.RELEASE
2.9.0

   redis.clients
   jedis
   ${jedis}
   true



   io.lettuce
   lettuce-core
   ${lettuce}
   true


而开始的重连输出就是由包lettuce-core打印的，开始以为重连是因为连接redis失败导致的，放大了超时时间，没有用，于是研究官网说明没看到特殊配置，终于在https://github.com/lettuce-io/lettuce-core/issues/861看到了原因，

Lettuce is designed to maintain long-lived connections. Summarizing this issue, Lettuce behaves as designed as it reconnects after Redis disconnects idle connections regularly.

所以该提示只是包的info级别log,可以在日志配置文件中设置包日志输出级别

eg:

    

or 
log4j.logger.my.pkg=info
