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.

这句话是什么意思？

这句话是关于跨域资源共享（CORS）的。当设置 allowCredentials 为 true 时，表示允许请求携带凭证信息，例如 cookie 等。但是，如果 allowedOrigins 中包含了通配符 "*"，则无法设置响应头中的 "Access-Control-Allow-Origin" 为 "* "，因为这是不允许的。此时，需要明确列出允许的 origin，或者考虑使用 allowedOriginPatterns。allowedOriginPatterns 允许使用正则表达式来匹配多个允许的 origin。

这是一个Java异常，意思是当设置allowcredentials为true时，allowedorigins不能包含特殊值“*”，因为这个值不能被设置在“access-control-allow-origin”响应头中。如果要允许一组来源的凭据，需要明确列出它们，或者考虑使用“allowedoriginpatterns”代替。

当allowcredentials为true时，allowedorigins不能包含特殊值"*"，因为该值无法在"access-control-allow-origin"响应头中设置。要允许特定的来源访问凭据，需要明确列出这些来源，或者考虑使用"allowedori"来设置。
