[restartedMain] ERROR org.springframework.boot.SpringApplication – Application run failed
java.lang.IllegalStateException: Failed to load property source from location ‘classpath:/application.yml’

Caused by: org.yaml.snakeyaml.scanner.ScannerException: while scanning for the next token
found character ‘@’ that cannot start any token. (Do not use @ for indentation)
in ‘reader’, line 17, column 13:
active: @spring.active@
^

解决办法：

方式一：

在 application.yml中 将 active: @spring.active@ 加上英文引号，

改为 active: “@spring.active@”

方式二：

使用阿里云的maven仓库，在项目根目录右键，并点击maven的reimport。
