--------------------

## 原因分析： ##

从springcloud2020.0.1开始不再默认支持bootstrap

本次启动错位是因为springcloud的版本迭代引起的，那么问题就很好解决了，只需要在pom.xml文件中重新引入相关的额依赖就行

--------------------

## 解决方案： ##

在pom.xml引入BootStrap的依赖

<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-bootstrap</artifactId>
                <version>3.0.2</version>
            </dependency>
