我正在关注本教程：developing restful apis with kotlin使用Auth0

但是，当我运行该应用程序时，会引发以下错误

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'webSecurity': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'auth0.audience' in value "${auth0.audience}"

添加您的application.properties：

 # this is the identifier of the API that we just created
 auth0.audience=kotlin-jwts
 # replace YOUR-DOMAIN to get something like https://bkrebs.auth0.com/
 auth0.issuer=https://YOUR-DOMAIN.auth0.com/
