@Configuration
public class CorsConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                //是否发送Cookie
                .allowCredentials(true)
                //放行哪些原始域
                //.allowedOrigins("*")
                .allowedOriginPatterns("*")
                .allowedMethods("GET", "POST", "PUT", "DELETE")
