java web解决跨域问题，亲测有效！

@Configuration
public class BeanConfiguration {
    @Bean
     public CorsFilter corsFilter() {
                final UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource = new UrlBasedCorsConfigurationSource();
                final CorsConfiguration corsConfiguration = new CorsConfiguration();
                corsConfiguration.setAllowCredentials(true);
                 corsConfiguration.addAllowedOrigin("*");
                 corsConfiguration.addAllowedHeader("*");
                 corsConfiguration.addAllowedMethod("*");
                 urlBasedCorsConfigurationSource.registerCorsConfiguration("/**", corsConfiguration);
                 return new CorsFilter(urlBasedCorsConfigurationSource);
             }

}
