经常碰到修改application.yaml文件之后,SpringBoot项目启动失败的,报错信息如下

从【java.lang.IllegalStateException: Failed to load property source from 'file:/G:/Program/JAVA_WorkSpace/project1/Cloud/redis-demo/target/classes/application.yaml'】可以看出来是配置文件的问题,这个问题一般是配置文件编码格式不对。一般都是改了配置,加了一些中文注释之类的导致项目无法启动。

解决方案:

方案1:

删除非英文部分的字符

方案2:

以IDEA为例,把圈起来的地方全都设置为UTF-8,然后重新启动。
