配置Swagger之后无法启动服务

Posted 2020-11-26 randlly

 

1、注释错误引起（application.yml采用的是#注释而不是//）

 

 

 2、直接从代码中标红的地方就能看出，在我们的配置文件（.properties/.yml）中缩进采用tab而不是空格引起的（不同配置之间也不能有tab出现，否则会报错）

 

　　

 

 从图中标红的地方我们就可以看出，在我们的配置中使用了缩进，而不是空格

 3、配置文件的编码格式跟项目的编码格式不一致

 

4、冒号后面必须有空格否则会报错

 

从图中的 颜色我们就能看出，值和属性名一致，可知此处有问题。
