springboot添加资源路径映射

@SpringBootApplication
public class App implements WebMvcConfigurer{
	public static void main(String[] args) {
		SpringApplication.run(App.class, args);
	}
	public static String uploadPath;
	
	
	@Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
		
            registry.addResourceHandler("/upload/**").addResourceLocations("file:F:\\BBB\\");
    }
}
