具体功能如图:上传按钮
vue前台代码:
上传
vue绑定方法:
handleRemove(file, fileList) { console.log(file, fileList); }, handleProgress(event, file, fileList){ this.loading = Loading.service({ lock: true, text: '程序正在升级,请耐心等待;或者完毕后手动刷新', spinner: 'el-icon-loading', background: 'rgba(0, 0, 0, 0.7)' }) }, handlePreview(file) { console.log(file); }, beforeRemove(file, fileList) { return this.$confirm(`确定移除 ${file.name}?`); }, handleSuccess(res, file, fileList) { console.log(res); if (res.flag) { this.$message.success(res.message); this.findUpgradeFileVersion(); } else { this.$message.error(res.message); } }, handleError(res, file, fileList) { let errorStr = res.toString(); let errorStr2 = errorStr.replace("Error:",""); const Error = JSON.parse(errorStr2); this.$message.error(Error.error_description); this.loading.close() },
Java后台代码实现:代码仅供参考,根据具体业务,再进行修改
public Result getUploadFile(@RequestBody MultipartFile file) throws IOException { if (file != null) { //文件大小 KB单位 long size = file.getSize(); //获取上传文件的原文件名 String dirPath = System.getProperty("user.dir") + File.separator + "client_upgrade"; String src_file_name = file.getOriginalFilename(); //储存文件 String savePath = dirPath + File.separator + src_file_name; boolean saveFile = upgradeUtil.saveFileForClient(file, savePath); if (!saveFile) { throw new FortException(new FortError(StatusCode.ERROR, "文件存储失败")); } //声明json序列化对象 // ObjectMapper mapper = new ObjectMapper(); //解压客户端升级包,读取新版本号和版本描述 Mapmap = upgradeUtil.getClientVerAndDes(savePath, dirPath, src_file_name); if (map == null) { throw new FortException(new FortError(StatusCode.ERROR, "获取版本信息及其升级文件名失败")); } //获取当前登录用户名 //在security中获取认证后的对象 Authentication authentication = SecurityContextHolder.getContext().getAuthentication(); //获取当前登录的对象 User user = (User) authentication.getPrincipal(); return new Result(true, StatusCode.OK, "上传成功"); } else { return new Result(false, StatusCode.ERROR, "上传失败"); } } @RequestMapping("/findUpgradeFileVersion") public Result findUpgradeFileVersion() { List upgradeFileList = upgradeFileService .findUpgradeFile(); return new Result(true, StatusCode.OK, "成功", upgradeFileList); }
