spring-boot - Spring actuator 在启动期间错误退出健康检查：RedisReactiveHealthIndicator：Redis 健康检查失败

Question

在 spring boot 升级到2.2.11.RELEASE后，我们看到以下错误。我认为第一次运行状况检查是否因以下错误而失败，但是当我调用运行状况端点时，我看到运行状况检查成功。

2020-12-28 05:42:08.840 WARN 1 --- [oundedElastic-8] osbarRedisReactiveHealthIndicator：Redis 健康检查失败 org.springframework.data.redis.RedisConnectionFailureException：无法连接到 Redis；嵌套异常是 io.lettuce.core.RedisConnectionException: Unable to connect to xc-dev-redis.xylem-cloud.com:6379 at org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory$ExceptionTranslatingConnectionProvider.translateException(LettuceConnectionFactory.java :1511) ~[spring-data-redis-2.2.11.RELEASE.jar!/:2.2.11.RELEASE] at org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory$ExceptionTranslatingConnectionProvider.getConnection(LettuceConnectionFactory.java: 1419）〜[spring-data-redis-2.2.11.RELEASE.jar！/：2.2.11.RELEASE]在org.springframework.data.redis.connection.lettuce。

这是来自健康端点的响应：
