SpringBoot解决前后端全局跨域问题WebMvcConfigurer

今天前端告诉我说，访问外部静态文件出现跨域。一不做二不休，直接改成全局允许跨域

@Configuration
public class CorsConfig extends WebMvcConfigurer {

     @Override  
        public void addCorsMappings(CorsRegistry registry) {  
            registry.addMapping("/**")  
                    .allowedOrigins("*")  
                    .allowCredentials(true)  
                    .allowedMethods("GET", "POST", "DELETE", "PUT","PATCH")  
                    .maxAge(3600);  
        }  
}
