SpringBoot 启动异常 Failed to load property source from location ‘classpath:/application.yml‘

主要异常信息如下：

java.lang.IllegalStateException: Failed to load property source from location 'classpath:/application.yml'

Caused by: org.yaml.snakeyaml.error.YAMLException: java.nio.charset.Malforme

Exception in thread "main" java.nio.charset.MalformedInputException: Input length = 1

SpringBoot启动加载yml配置文件出现编码格式错误

解决方式：

1、先改idea编码--file-settings--file Encodings 修改如图

2、将原来的application.yml文件删除掉，然后重新建创建一个application.yml 后再次重启。结果正常！！！
