Nginx 反向代理解决跨域问题

1、Nginx 配置
http {
    underscores_in_headers on;

    upstream monitor_server {
        server 127.0.0.1:8085;
        #server 127.0.0.1:5050;
    }
    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-Server $proxy_add_x_forwarded_for;
            proxy_set_header Access-Control-Allow-Origin *;
            proxy_pass  http://monitor_server;
        }
}
2、服务器端springboot
@Configuration
public class CorsConfig {
    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        return corsConfiguration;
    }

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig());
        return new CorsFilter(source);
    }

}
