@Configuration
public class GlobalCorsConfig {
 @Bean
 public CorsFilter corsFilter() {
 //1、添加CORS配置信息
 CorsConfiguration config = new CorsConfiguration();
 //2、允许写的域，不要写*，否则cookie就无法使用了
 config.addAllowedOrigin("http://manage.leyou.com");
 config.addAllowedOrigin("http://api.leyou.com");
 //3、是否发送cookie信息
 config.setAllowCredentials(true);
 //4、允许的请求方式
 config.addAllowedMethod("OPTIONS");
 config.addAllowedMethod("GET");
 config.addAllowedMethod("POST");
 config.addAllowedMethod("HEAD");
 config.addAllowedMethod("PUT");
 config.addAllowedMethod("DELETE");
 config.addAllowedMethod("PATCH");
 //5、允许的头信息
 config.addAllowedHeader("*");
 //6、有效时长
 config.setMaxAge(3600L);
 //7、添加映射路径,拦截一切请求
 UrlBasedCorsConfigurationSource configSource = new UrlBasedCorsConfigurationSource();
 configSource.registerCorsConfiguration("/**",config);
 //8、返回新的CorsFilter
 return new CorsFilter(configSource);
 }
