spring cloud gateway 跨域解决

在spring cloud集成了gateway后，前端分离代码还没法直接访问，会出现跨域错误，找了好多方案都不行，最后在stackoverflow找到，亲测有效，记录一下：

在gateway项目中添加配置文件，代码：

package com.example.gateway.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpHeaders;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.reactive.CorsWebFilter;
import org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource;
import org.springframework.web.reactive.config.CorsRegistry;
import org.springframework.web.reactive.config.WebFluxConfigurer;

@Configuration
public class CorsConfig implements WebFluxConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowCredentials(true)
                .allowedOrigins("*")
                .allowedHeaders("*")
                .allowedMethods("*")
                .exposedHeaders(HttpHeaders.SET_COOKIE);
    }

    @Bean
    public CorsWebFilter corsWebFilter() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.setAllowCredentials(true);
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.addExposedHeader(HttpHeaders.SET_COOKIE);
        UrlBasedCorsConfigurationSource corsConfigurationSource = new UrlBasedCorsConfigurationSource();
        corsConfigurationSource.registerCorsConfiguration("/**", corsConfiguration);
        return new CorsWebFilter(corsConfigurationSource);
    }
}
