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.
at org.springframework.web.cors.CorsConfiguration.validateAllowCredentials(CorsConfiguration.java:460)
Suppressed: reactor.core.publisher.FluxOnAssembly$OnAssemblyException:
Error has been observed at the following site(s):
|_ checkpoint ⇢ org.springframework.cloud.gateway.filter.WeightCalculatorWebFilter [DefaultWebFilterChain][from www.fhadmin.org]
问题原因，新版本的gateway 取消了allowedOrigins， 对应的变更为 allowedOriginPatterns
配置修改为：
#--------gateway配置--------
#使用服务发现路由
spring.cloud.gateway.discovery.locator.enabled=true
#服务路由名小写
spring.cloud.gateway.discovery.locator.lower-case-service-id=true
#跨域配置(java www.fhadmin.org)
spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowedOriginPatterns=*
spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowedHeaders=*
spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowedMethods=*
spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowCredentials=true一：springcloud服务 -----------------------
