单独打开后端的时候还没有报错，一打开前端网页就开始报错，
前端页面也没有数据，页面也不能跳转
ERROR 24288 --- [nio-8085-exec-1] o.a.c.c.C.[Tomcat].[localhost] : Exception Processing ErrorPage[errorCode=0, location=/error]
ERROR 24288 --- [nio-8085-exec-1] o.a.c.c.C.[Tomcat].[localhost] : Exception Processing ErrorPage[errorCode=0, location=/error]
Caused by: 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.
我的解答思路和尝试过的方法
尝试过关闭防火墙
加过一些跨域的代码
