【跨域问题】When allowCredentials is true, allowedOrigins cannot contain the special value “*“ since that

在springboot中配置跨域时，出现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.

需要将配置类中的corsConfiguration.addAllowedOrigin("");修改成为corsConfiguration.addAllowedOriginPattern("");

修改前的代码：

package com.oolong.gulimall.gateway.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.reactive.CorsWebFilter;
import org.springframework
