2.WebConfig类：

package com.hongyi.cms.facereport.config;

import org.springframework.beans.factory.annotation.Value;
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 WebConfig implements WebMvcConfigurer {
    @Value("${upload.path}")
    private String uploadPath;

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        /**
         * 访问路径：http://localhost:93/facereport/static/captured/daping_report/captured_images/face/788001414206074880/2021/1/27/cj_142207194912440320.png
         * "/facereport/static/captured/**" 为前端URL访问路径
         * "file:" + uploadPath 是本地磁盘映射
         */
        registry.addResourceHandler("/facereport/static/captured/**").addResourceLocations("file:" + uploadPath);
    }

}

3.@Value("${upload.path}")在yml里配置：

4.前端url访问：http://localhost:93/facereport/static/captured/daping_report/captured_images/face/788001414206074880/2021/1/27/1.jpg

成功映射，并显示：
