springboot2.0跨域配置（转）

　springboot2.0跨域配置： 

一、代码 

@Value("${cors.allowOrigin.url:anyValue}")
private String corsAllowOriginUrl;
@ConditionalOnProperty(name="cors.allowOrigin.enable", havingValue="true", matchIfMissing=false)
@Bean
public CorsFilter corsFilter() {
  final UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource = new UrlBasedCorsConfigurationSource();
  final CorsConfiguration corsConfiguration = new CorsConfiguration();
  corsConfiguration.setAllowCredentials(true);
  corsConfiguration.addAllowedOrigin("*");
  corsConfiguration.addAllowedHeader("*");
  corsConfiguration.addAllowedMethod("*");
  log.debug("启用跨域，允许域名：{}",corsAllowOriginUrl);
  urlBasedCorsConfigurationSource.registerCorsConfiguration(corsAllowOriginUrl, corsConfiguration);
  return new CorsFilter(urlBasedCorsConfigurationSource);
}

二、application.properties 
　　可以通过参数cors.allowOrigin.enable，控制是否允许跨域。 

cors.allowOrigin.url=https://servicewechat.com
cors.allowOrigin.enable=false
