### 问题
1.Eureka控制台出现
EMERGENCY! EUREKA MAY BE INCORRECTLY CLAIMING INSTANCES ARE UP WHEN THEY'RE NOT. RENEWALS ARE LESSER THAN THRESHOLD AND HENCE THE INSTANCES ARE NOT BEING EXPIRED JUST TO BE SAFE.
1. Eureka控制台出现
EMERGENCY! EUREKA MAY BE INCORRECTLY CLAIMING INSTANCES ARE UP WHEN THEY'RE NOT. RENEWALS ARE LESSER THAN THRESHOLD AND HENCE THE INSTANCES ARE NOT BEING EXPIRED JUST TO BE SAFE.
说明Eureka已经进入了保护模式。
2. @value 如果配置文件中没有这个配置项且没有指定默认值,则会报错:
Could not resolve placeholder 'xxx' in value "${aaa.bbb.ccc}"
@value指定默认的方法
```
@Value("${aaa.bbb.ccc:DefaultValue}")
```
3. docker 安装ELK(https://www.jianshu.com/p/f4812c21d6a8)
