本地好几个项目启动都是突然报了以上的错误，
出现这个的原因，就是解析yml文件时，中文字符集不是utf-8的原因或者有的项目就是GBK形式的，改成UTF-8反而还是会报错，改成GBK不报错，也有可能。
以下是我个人自己尝试了总结的解决方法

解决办法

一、检查pom文件
我们首先需要在pom文件中设置，编译时编码utf-8即可。

<properties>
   <java.version>1.8</java.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <maven.compiler.encoding>UTF-8</maven.compiler.encoding>
</properties>
