你们跟着敲的时候没遇到同样的问题？？？？
后来仔细看了一下，发现服务其实启动成功了，报错的是：
o.s.b.a.health.RedisHealthIndicator : Health check failed
于是跟进源码，发现RedisHealthIndicator属于
org.springframework.boot.actuate.health
原来是springboot的组件连结的健康检查监控，既然这样，应该是可以配置关闭检查的，但是怎么关，上官网，就搜 RedisHealthIndicator，没想到还真有。
**
It is possible to disable them all using the management.health.defaults.enabled property.
**
可以disable的
再搜
management.health.defaults.enabled还真有
这个是默认 是Enable default health indicators，下面还有一个management.health.redis.enabled，那直接在application.properties中加入management.health.redis.enabled=false。restart，果然没问题了。
原来项目中依赖了spring-boot-starter-data-redis，看来依赖了redis，他会默认去检查连接，但是3-6课还没有使用redis，所以还没配置连接属性。
接着我想直接把这个包干掉，应该也不会有连结检查了，然后删掉了core的pom中的spring-boot-starter-data-redis依赖，结果项目报错，发现UserController的Pageable是spring-boot-starter-data-redis的spring-data-common中的，先删除试一下，restart，发现也成功了。
考虑到后面会用到redis，于是恢复了代码，然后现将redis的健康检查disabled：
application.properties中加入management.health.redis.enabled=false
这个坑，看视频的时候居然没有出现，很奇怪。
