gateway 跨域问题解决方案

【gateway 跨域问题解决方案】1.写个配置类CorsConfig (如果不行，可以不写此类，和springcloud的版本有关)
package net.youqu.micro.service.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.web.cors.reactive.UrlBasedCorsConfigurationSource;import org.springframework.web.util.pattern.PathPatternParser;/** * description: * java项目www.fhadmin.org */@Configurationpublic class CorsConfig {@Beanpublic CorsWebFilter corsFilter() {CorsConfiguration config = new CorsConfiguration();config.addAllowedMethod("*");config.addAllowedOrigin("*");config.addAllowedHeader("*");UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(new PathPatternParser());source.registerCorsConfiguration("/**", config);return new CorsWebFilter(source);}}2. 配置 application.properties 方式
#--------gateway配置--------#跨域配置spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowedOrigins=*spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowedHeaders=*spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowedMethods=*spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowCredentials=trueyaml 方式

1.nacos 阿里注册中心：官方eureka停止更新，目前比较好的取代者就是nacos
2.zipkin 跟踪服务：分布式跟踪日志,基于内存存储记录
3.gateway 网关路由服务：分发请求，统一管理过滤，结合 ribbon 负载均衡、feign服务调用
4.springboot-admin 监控中心服务：统一界面管理，查看各个服务运行状态 actuator健康检查
5.sentinel 高可用流量管理框架：以流量为切入点，限流、流量整形、熔断降级、系统负载保护、热点防护
