代码示例如下

@Configuration
public class CustomCorsFilter {

    @Bean
    public CorsConfiguration configuration() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.addAllowedOrigin("*");
        configuration.addAllowedMethod("*");
        configuration.addAllowedHeader("*");
        // 只有当 addAllowedOrigin 指定具体的域名时才能开启此项配置
        // configuration.setAllowCredentials(true);
        return configuration;
    }

    @Bean
    public CorsFilter corsFilter(CorsConfiguration configuration) {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return new CorsFilter(source);
    }

}
