在springboot项目中配置跨域

我的蚂蚁笔记博客

在Appplication.java添加：

private CorsConfiguration buildConfig() {          CorsConfiguration corsConfiguration = new CorsConfiguration();          corsConfiguration.addAllowedOrigin("*");          corsConfiguration.addAllowedHeader("*");          corsConfiguration.addAllowedMethod("*");          return corsConfiguration;      }            /**      * 跨域过滤器      * @return      */      @Bean      public CorsFilter corsFilter() {          UrlBasedCorsConfigurationSource sourc= new UrlBasedCorsConfigurationSource();          source.registerCorsConfiguration("/**", buildConfig()); // 4          return new CorsFilter(source);      }
