1、經排查研究後，在POM中新增如下依賴 ，可解決Completed shut down of DiscoveryClient

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

2、No active profile set, falling back to default profiles: default 這個錯誤可通過以下方式解決。
