springboot 2.2.3之spring-boot-starter-data-redis-reactive配置异常

spring配置如下

redis:
    database: ${REDIS_DATABASE:0}
    host: ${REDIS_HOST:139.223.123.123}
    port: ${REDIS_PORT:6379}
    password: ${REDIS_PASSWORD:123456}
    lettuce:
      pool:
        max-active: 200 #连接池最大连接数（使用负值表示没有限制）

异常如下

Caused by: org.springframework.data.redis.RedisConnectionFailureException: Unable to connect to Redis; nested exception is io.lettuce.core.RedisConnectionException: Unable to connect to localhost:6379
Caused by: io.lettuce.core.RedisConnectionException: Unable to connect to localhost:6379
Caused by: io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: localhost/127.0.0.1:6379
Caused by: java.net.ConnectException: Connection refused: no further information

问题

目前的springboot升级版本为2.2.3，在项目启动时，无法正常加载配置的redis地址，（永远都是“localhost”），之前的版本为2.1.4，项目正常启动。
目前正在查找问题原因
