错误信息：

Caused by: java.lang.IllegalStateException: Attempted to load applicationConfig: [file:../config/application.yml] but snakeyaml was not found on the classpath

打包后运行程序提示加载配置文件异常，在pom.xml增加

<dependency>
    <groupId>org.yaml</groupId>
    <artifactId>snakeyaml</artifactId>
    <version>1.23</version>
</dependency>

后重新编译打包解决！此问题常见于使用assembly打包项目时。
