springboot 配置类添解决跨域问题

@Configuration
public class GlobalCorsConfig {
    @Bean
    public CorsFilter corsFilter() {
        //1.添加CORS配置信息
        CorsConfiguration config = new CorsConfiguration();
        //1) 允许的域,不要写*，否则cookie就无法使用了
        config.addAllowedOrigin("http://127.0.0.1:6001");
        config.addAllowedOrigin("http://localhost:6001");
        //2) 是否发送Cookie信息
        config.setAllowCredentials(true);
        //3) 允许的请求方式
        config.addAllowedMethod("OPTIONS");
        config.addAllowedMethod("HEAD");
        config.addAllowedMethod("GET");
        config.addAllowedMethod("PUT");
        config.addAllowedMethod("POST");
        config.addAllowedMethod("DELETE");
        config.addAllowedMethod("PATCH");
        // 4）允许的头信息
        config.addAllowedHeader("*");
        //2.添加映射路径，我们拦截一切请求
        UrlBasedCorsConfigurationSource configSource = new
                UrlBasedCorsConfigurationSource();
        configSource.registerCorsConfiguration("/**", config);
        //3.返回新的CorsFilter.
        return new CorsFilter(configSource);
    }
