Spring Boot 解决cors跨域

1. CorsUtil配置类

   @Configuration
   public class CorsUtil {
   
       @Bean
       public WebMvcConfigurer corsConfigurer() {
   
           return new WebMvcConfigurer() {
               @Override
               public void addCorsMappings(CorsRegistry registry) {
                   registry.addMapping("/**");
               }
           };
       }
   }
