  bucket-name: pic # 基础目录 可不设置 添加该目录后所有通过api操作的文件或者bucket都将在该目录下

template注入

private final MinioTemplate minioTemplate;

单文件上传

@PostMapping("/upload")
@ApiOperation(value = "文件上传", notes = "文件上传")
public R upload(@RequestParam("file") MultipartFile file, String folder) {
    folder = Optional.ofNullable(folder).orElse(CommonConstants.BUCKET_NAME);

    } catch (Exception e) {
        log.error("上传失败", e);
        return R.failed(e.getLocalizedMessage());
    }
    return R.ok(resultMap);
}

文件删除

@ApiOperation(value = "通过文件名称删除文件管理", notes = "通过文件名称删除文件管理")

文件预览

@GetMapping("/{bucket}/{fileName}")
@ApiOperation(value = "文件读取", notes = "文件读取")
public void file(@PathVariable String bucket, @PathVariable String fileName, HttpServletResponse response) {
