一、application.yaml 配置

  sms-code: # 短信验证码相关的配置项expire-times: 10msend-frequency: 1msend-maximum-quantity-per-day: 10begin-code: 9999 # 这里配置 9999 的原因是，测试方便。end-code: 9999 # 这里配置 9999 的原因是，测试方便。trade:order:pay-expire-time: 2h # 支付的过期时间receive-expire-time: 14d # 收货的过期时间comment-expire-time: 7d # 评论的过期时间express:client: KD_NIAOkd-niao:api-key: cb022f1e-48f1-4c4a-a723-9001ac9676b8business-id: 1809751request-type: 1002 # 免费版 1002；付费版 8001kd100:key: pLXUGAwK5305customer: E77DF18BE109F454A5CD319E44BF5177file:upload-dir: /data/home/huangjiaqi/agent-saas/agent-saas-api/pictures  # 文件上传存储路径max-size: 15MB  # 单文件大小限制allowed-types: image/jpeg,image/png,image/gif  # 允许的文件类型

关键配置说明：

upload-dir: 文件存储的服务器绝对路径
max-size: 限制上传文件大小（示例为15MB）
allowed-types: 限制可上传的文件类型

二、上传代码

@Tag(name = "文件上传")
@RestController
@RequestMapping("/admin-api/file")
public class FileUploadController {@Value("${yudao.file.upload-dir}")private String uploadDir;@PostMapping("/upload")@Operation(summary = "单文件上传")@PermitAllpublic AjaxResult uploadFile(@RequestParam("file") MultipartFile file) {try {// 1. 校验文件if (file.isEmpty()) {return AjaxResult.error("文件不能为空");}if (file.getSize() > 15 * 1024 * 1024) {return AjaxResult.error("文件大小不能超过15MB");}// 2. 调用工具类上传String filePath = FileUploadUtil.upload(file, uploadDir);// 3. 解析文件信息String originalFilename = file.getOriginalFilename();String fileSuffix = originalFilename.substring(originalFilename.lastIndexOf("."));String newFileName = filePath.substring(filePath.lastIndexOf("/") + 1);// 4. 从uploadDir中提取相对路径部分// 假设uploadDir是绝对路径，我们需要获取最后一个目录名// 例如：/data/home/huangjiaqi/agent-saas/agent-saas-api/pictures → 获取 "pictures"String relativePath = uploadDir.substring(uploadDir.lastIndexOf("/") + 1);// 5. 构建返回结果Map<String, Object> map = new HashMap<>();map.put("fileUrl", "/" + relativePath + filePath); // 完整相对路径map.put("originalSize", file.getSize());map.put("fileSuffix", fileSuffix);     // 文件后缀（如 ".png"）map.put("newFileName", newFileName);   // 新文件名（带后缀）map.put("originalName", originalFilename);  // 原文件名return AjaxResult.success(map);} catch (Exception e) {return AjaxResult.error("上传失败：" + e.getMessage());}}
}

三、成功响应示例

{"msg": "操作成功","code": 0,"data": {"originalName": "美女0005.png","fileSuffix": ".jepg","newFileName": "202506060950488009.jpeg","fileUrl": "/pictures/2025/06/202506060950488009.jpeg","originalSize": 231422}
}
