SpringBoot跨域配置，解决跨域上传文件

@SpringBootApplication
public class Application {

private CorsConfiguration buildConfig() {
CorsConfiguration corsConfiguration = new CorsConfiguration();
corsConfiguration.addAllowedOrigin("*");
corsConfiguration.addAllowedHeader("*");
corsConfiguration.addAllowedMethod("*");
corsConfiguration.setAllowCredentials(true);//这两句不加不能跨域上传文件，
corsConfiguration.setMaxAge(3600l);//加上去就可以了
return corsConfiguration;
}

/**
* 跨域过滤器
* @return
*/
@Bean
public CorsFilter corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", buildConfig()); // 4
return new CorsFilter(source);
}




public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
