1. 项目背景
唉!本文写起来都是泪点。不是刻意写的本文,主要是对日常用到的文件上传做了一个汇总总结,同时希望可以给用到的小伙伴带来一点帮助吧。
- 上传本地,这个就不水了,基本做技术的都用到过吧;
- 阿里云OSS,阿里云是业界巨鳄了吧,用到的人肯定不少吧,不过博主好久不用了,简单记录下;
- 华为云OBS,工作需要,也简单记录下吧;
- 七牛云,个人网站最开始使用的图床,目的是为了白嫖10G文件存储。后来网站了升级了https域名,七牛云免费只支持http,https域名加速是收费的。https域名的网站在谷歌上请求图片时会强制升级为https。
- 又拍云,个人网站目前在用的图床,加入了又拍云联盟,网站底部挂链接,算是推广合作模式吧(对我这种不介意的来说就是白嫖)。速度还行,可以去我的网站看一下:笑小枫
还有腾讯云等等云,暂没用过,就先不整理了,使用都很简单,SDK文档很全,也很简单。
2. 上传思路
分为两点来说。本文的精华也都在这里了,统一思想。
2.1 前端调用上传文件
前端上传的话,应该是我们常用的吧,通过
@RequestParam(value = "file") MultipartFile file
接收,然后转为
InputStream
or
byte[]
or
File
,然后调用上传就可以了,核心也就在这,很简单的,尤其上传到云服务器,装载好配置后,直接调用SDK接口即可。
2.2 通过url地址上传网络文件
通过url上传应该很少用到吧,使用场景呢,例如爬取文章的时候,把网络图片上传到自己的图床;图片库根据url地址迁移。
说到这,突然想起了一个问题,大家写文章的时候,图片上传到图床后在文章内是怎么保存的呢?是全路径还是怎么保存的?如果加速域名换了,或者换图床地址了,需要怎么迁移。希望有经验的大佬可以留言指导!
3. 上传到本地
这个比较简单啦,贴下核心代码吧
- 在yml配置下上传路径
file:local:maxFileSize:10485760imageFilePath: D:/test/image/
docFilePath: D:/test/file/
- 创建配置类,读取配置文件的参数
packagecom.maple.upload.properties;importlombok.Data;importorg.springframework.beans.factory.annotation.Value;importorg.springframework.context.annotation.Configuration;/**
* 上传本地配置
*
* @author 笑小枫
* @date 2022/7/22

*/@Data@ConfigurationpublicclassLocalFileProperties{// ---------------本地文件配置 start------------------/**
* 图片存储路径
*/@Value("${file.local.imageFilePath}")privateString imageFilePath;/**
* 文档存储路径
*/@Value("${file.local.docFilePath}")privateString docFilePath;/**
* 文件限制大小
*/@Value("${file.local.maxFileSize}")privatelong maxFileSize;// --------------本地文件配置 end-------------------}
- 创建上传下载工具类
packagecom.maple.upload.util;importcom.maple.upload.properties.LocalFileProperties;importlombok.AllArgsConstructor;importlombok.extern.slf4j.Slf4j;importorg.apache.commons.lang3.StringUtils;importorg.springframework.stereotype.Component;importorg.springframework.web.multipart.MultipartFile;importjavax.servlet.ServletOutputStream;importjavax.servlet.http.HttpServletResponse;importjava.io.File;importjava.io.FileInputStream;importjava.io.IOException;importjava.io.UnsupportedEncodingException;importjava.net.URLDecoder;importjava.nio.charset.StandardCharsets;importjava.nio.file.Files;importjava.text.SimpleDateFormat;importjava.util.*;/**

outputStream.write(buf,0, readLength);
readLength = inputStream.read(buf,0, length);}
outputStream.flush();}catch(Exception e){
e.printStackTrace();}}}
访问图片的话,可以通过重写
WebMvcConfigurer
的
addResourceHandlers
方法来实现。
通过请求
/local/images/**
将链接虚拟映射到我们配置的
localFileProperties.getImageFilePath()
下,文件访问同理。
详细代码如下
packagecom.maple.upload.config;importcom.maple.upload.properties.LocalFileProperties;importlombok.AllArgsConstructor;importorg.springframework.context.annotation.Configuration;importorg.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;importorg.springframework.web.servlet.config.annotation.WebMvcConfigurer;/**
* @author 笑小枫 <https://www.xiaoxiaofeng.com/>
* @date 2024/1/10
*/@Configuration@AllArgsConstructorpublicclassLocalFileConfigimplementsWebMvcConfigurer{privatefinalLocalFileProperties localFileProperties;@OverridepublicvoidaddResourceHandlers(ResourceHandlerRegistry registry){// 重写方法// 修改tomcat 虚拟映射// 定义图片存放路径
registry.addResourceHandler("/local/images/**").addResourceLocations("file:"+ localFileProperties.getImageFilePath());//定义文档存放路径
registry.addResourceHandler("/local/doc/**").addResourceLocations("file:"+ localFileProperties.getDocFilePath());}}
- controller调用代码
packagecom.maple.upload.controller;importcom.maple.upload.util.LocalFileUtil;importlombok.AllArgsConstructor;importlombok.extern.slf4j.Slf4j;importorg.springframework.web.bind.annotation.*;importorg.springframework.web.multipart.MultipartFile;importjavax.servlet.http.HttpServletResponse;importjava.util.List;importjava.util.Map;/**
* 文件相关操作接口
*
* @author 笑小枫
* @date 2024/1/10
* @see <a href="https://www.xiaoxiaofeng.com">https://www.xiaoxiaofeng.com</a>
*/@Slf4j@RestController@AllArgsConstructor@RequestMapping("/local")publicclassLocalFileController{privatefinalLocalFileUtil fileUtil;/**
* 图片上传
*/@PostMapping("/uploadImage")publicStringuploadImage(@RequestParam(value ="file")MultipartFile file){if(file.isEmpty()){thrownewRuntimeException("图片内容为空,上传失败!");}return fileUtil.uploadImage(file);}/**
* 文件批量上传
*/@PostMapping("/uploadFiles")publicList<Map<String,Object>>uploadFiles(@RequestParam(value ="file")MultipartFile[] files){return fileUtil.uploadFiles(files);}/**
* 批量删除文件
*/@PostMapping("/deleteFiles")publicvoiddeleteFiles(@RequestParam(value ="files")String[] files){
fileUtil.deleteFile(files);}/**
* 文件下载功能
*/@GetMapping(value ="/download/{fileName:.*}")publicvoiddownload(@PathVariable("fileName")String fileName,HttpServletResponse response){try{
fileUtil.downLoadFile(response, fileName);}catch(Exception e){
log.error("文件下载失败", e);}}}
调用上传图片的接口,可以看到图片已经上传成功。
通过请求
/local/images/**
将链接虚拟映射我们图片上。
批量上传,删除等操作就不一一演示截图了,代码已贴,因为是先写的demo,后写的文章,获取代码片贴的有遗漏,如有遗漏,可以去文章底部查看源码地址。
