当我们导入了spring-boot-starter-actuator这个依赖后, SpringBoot会默认去监测一些信息。其中就包括redis、 会根据redis的默认初始配置， localhost:6379 尝试连接redis。如果我们没有用到redis， 启动就会报错
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
<version>2.2.1.RELEASE</version>
</dependency>
比如我在使用SpringBoot项目的时候，其中内置了Actuator的依赖， 启动报错
