时间：2021-04-23 00:44:58

controller

    // 扫描指定目录下的图片进行展示

    @RequestMapping("/showPics")

    public ModelAndView showPics(ModelAndView mv) {

        // 图片存放路径

        String picPath = Constant.CONFIG_PROPERTIES.getProperty("download.path");

        // 获取图片

        List<File> picList = MyFileUtils.listFilesBySuffixs(picPath, Constant.PIC_SUFFIXS, true);

        mv.setViewName("showPics");

        mv.addObject("picList", picList);

        return mv;

    }

配置文件（application.properties）

# 本地图片

spring.mvc.static-path-pattern=/image/**

spring.resources.static-locations=file:C://Temp/pic/

配置图片目录地址映射。
