zuul 跨域问题

1.注解跨域:

　　

@CrossOrigin(allowCredentials = "*")

　

2. 配置config

package com.example.apigeteway.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

import java.util.Arrays;

/**
 * @Title: CorsConfig
 * @ProjectName api-geteway
 * @date 2019/12/1816:36
 */
@Configuration
public class CorsConfig {
    @Bean
    public CorsFilter corsFilter() {
        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        final CorsConfiguration config = new CorsConfiguration();

        config.setAllowCredentials(true);
        config.setAllowedOrigins(Arrays.asList("*")); //http:www.a.com 配置允许的url
        config.setAllowedHeaders(Arrays.asList("*"));
        config.setAllowedMethods(Arrays.asList("*"));
        config.setMaxAge(300l);

        source.registerCorsConfiguration("/**", config);
        return new CorsFilter(source);
    }
}
