Springboot 基于过滤器的CORS支持
Spring框架还提供了CorsFilter。在这种情况下,不用使用@CrossOrigin或
WebMvcConfigurer#addCorsMappings(CorsRegistry)
,例如,可以在Spring Boot应用程序中声明如下的过滤器:
@Configuration public class MyConfiguration { @Bean public FilterRegistrationBean corsFilter() { UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(); CorsConfiguration config = new CorsConfiguration(); config.setAllowCredentials(true); config.addAllowedOrigin("http://domain1.com"); config.addAllowedHeader("*"); config.addAllowedMethod("*"); source.registerCorsConfiguration("/**", config); FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source)); bean.setOrder(0); return bean; } }
