java.lang.IllegalStateException: Failed to load property source from location 'classpath:/application-dev.yml'
如果你的项目没有配置错误,配置文件名称也正常,还出现这个问题,那一定是你的yml文件编码的问题
先附上一张项目架构图
当我启动服务器寻找配置文件的时候,服务器提示这样的错误信息

我的application.yml和application-dev.yml是没有配置错误的,而且我的文件名称是完全正常的,编译后的target文件里面也有application-dev.yml,我就很纳闷问题出在哪儿了!
打开target文件,查看application-dev.yml文件,发现这个文件居然是空的,说明这个文件编译失败了!!!
最后找到问题,因为这个文件的编码格式是GBK,项目的编码格式是UTF-8,里面有注释,注释乱码,导致编译失败
1.修改你的编码格式
2.删除注释
