问题

项目起动时，找不到yaml，各种处理还是没有解决，比如，clean，重启电脑，检查utf8等。

同事拉的新代码又是正常可以跑，这就有点奇怪了。

解决

最后是在右下角，先改成GBK，又改回UTF-8

yaml文件的编码也先改为GBK，又改回UTF-8

可能这文件用别的编辑器打开过，编码格式就换了。

还需要加如下：
 

        <dependency>
            <groupId>org.yaml</groupId>
            <artifactId>snakeyaml</artifactId>
            <version>1.29</version>
        </dependency>
