环境jdk17springbootVueElementUI 背景公司所做的项目需要别的系统向我们服务器上传文件当我们需要查看这些文件什么时候上传的、文件数据是怎样的只能去机房排查问题效率较低做此页面可快速查看上传的文件信息且可下载到本地查看。为了生产安全不支持修改及上传文件如果有的朋友想做可自行查找资料。 需求实现系统文件的查询及下载。展示系统的文件信息如文件名、文件大小、最后更新时间及权限等。 注意本篇文章是以window系统做的样例不过一般服务器都是在linux系统只需将前端的初始地址换成linux地址一般格式为/home/app。 效果图 直接上代码前端代码

好了主要的代码就这些。还有两个依赖 !-- 处理文件上传的 Java 库 --dependencygroupIdcommons-fileupload/groupIdartifactIdcommons-fileupload/artifactIdversion1.5/version/dependency!-- Apache 的开源工具库,包含了许多实用的文件操作、流操作相关的功能和工具类比如文件读写、文件和目录的操作、流的处理和转换 --dependencygroupIdcommons-io/groupIdartifactIdcommons-io/artifactIdversion2.5/version/dependency
