问题描述

java.lang.IllegalArgumentException: When allowCredentials is true, allowedOrigins cannot contain the special value "*"since that cannot be set on the “Access-Control-Allow-Origin” response header. To allow credentials to a set of origins, list them explicitly or consider using “allowedOriginPatterns” instead.

解决办法

错误是因为Spring boot版本过高，从而导致跨域未生效，我使用的是2.4.0报错，修改为2.3.0.RELEASE版本问题得到解决。
