spring boot 添加外部静态资源映射

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

	@Override
	public void addResourceHandlers(ResourceHandlerRegistry registry) {
		registry.addResourceHandler("/resources/**").addResourceLocations("file:c:/UploadResources/");
		WebMvcConfigurer.super.addResourceHandlers(registry);
	}

}

访问时则用：http://域名(端口)/项目context/resources/... 访问c:/UploadResources/资源文件夹里的资源
