gateway配置

spring:
  cloud:
    gateway:      
      globalcors:
        cors-configurations:
          '[/**]':
            allowCredentials: true
            allowedOrigins: "*"
            allowedMethods: "*"
            allowedHeaders: "*"        	

网上搜了一堆,大多都是上面的这些,但是如果只进行这样的配置的话,根本不会生效,我这边的gateway是集成了oauth2进行鉴权的,最后在Spring Security官方文档上看到了这一段

琢磨一番加参考其他博客之后。。。

gateway添加cros跨域配置文件

CorsConfig.java

import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.cloud.gateway.config.GlobalCorsProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;
import org.springframework.core.annotation.Order;
import org.springframework.web.cors.reactive.CorsWebFilter;
import org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource;
import org.springframework.web.util.pattern.PathPatternParser;


@Configuration
@EnableConfigurationProperties(GlobalCorsProperties.class)
public class CorsConfig {

    @Order(Ordered.HIGHEST_PRECEDENCE)
    @RefreshScope
    @Bean
    public CorsWebFilter corsWebFilter(GlobalCorsProperties globalCorsProperties){
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(new PathPatternParser());
        globalCorsProperties.getCorsConfigurations().forEach(source::registerCorsConfiguration);
        return new CorsWebFilter(source);
    }
}

本人实测原文的代码跨域也是有效
