2020-02-06 17:45:28.879 [main] ERROR org.springframework.boot.SpringApplication - Application run failed
java.lang.NoSuchMethodError: org.yaml.snakeyaml.nodes.ScalarNode.getScalarStyle()Lorg/yaml/snakeyaml/DumperOptions$ScalarStyle;
后来在pom中加载了代码
``` <dependency>
<groupId>org.yaml</groupId>
<artifactId>snakeyaml</artifactId>
<version>1.23</version>
</dependency>
还是不行，是不是对它的版本有要求。切换了1.25版本还是不行
完整版错误代码：

这个问题有可能是包没有下载成功。 你到.m2文件夹下，找到这个包的下载路径，把他们都删除掉，然后重新下载一下试试。
