介绍
数式Oinone默认提供了阿里云、腾讯云、华为云、又拍云、Minio和本地文件存储这几种文件存储系统，如果我们有其他的文件存储系统需要对接，或者是扩展现有的文件系统，可以通过SPI继承AbstractFileClient注册新的文件存储系统。
代码示例
这里以扩展自有的本地文件系统为例
继承了内置的本地文件存储LocalFileClient，将其中上传文件的方法重写
package pro.shushi.pamirs.demo.core.file;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.multipart.support.StandardMultipartHttpServletRequest;
import pro.shushi.pamirs.framework.connectors.cdn.client.LocalFileClient;
import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j;
import pro.shushi.pamirs.meta.common.spi.SPI;
import javax.servlet.http.HttpServletRequest;
@Slf4j
@Component
// 注册新的文件存储系统类型
@SPI.Service(DemoLocalFileClient.TYPE)
@RestController
@RequestMapping("/demo_file")
public class DemoLocalFileClient extends LocalFileClient {
public static final String TYPE = "DEMO_LOCAL";
@Override
public CdnFileForm getFormData(String fileName) {
CdnConfig cdnConfig = getCdnConfig();
CdnFileForm fileForm = new CdnFileForm();
String uniqueFileName = Spider.getDefaultExtension(CdnFileNameApi.class).getNewFilename(fileName);
String fileKey = getFileKey(cdnConfig.getMainDir(), uniqueFileName);
//前端获取uploadUrl,上传文件到该地址
fileForm.setUploadUrl(cdnConfig.getUploadUrl() + "/demo_file/upload");
//上传后,前端将downloadUrl返回给后端
fileForm.setDownloadUrl(getDownloadUrl(fileKey));
fileForm.setFileName(uniqueFileName);
Map<String, Object> formDataJson = new HashMap<>();
formDataJson.put("uniqueFileName", uniqueFileName);
formDataJson.put("key", fileKey);
fileForm.setFormDataJson(JSON.toJSONString(formDataJson));
return fileForm;
}
@ResponseBody
@RequestMapping(value = "/upload", produces = "multipart/form-data;charset=UTF-8",method = RequestMethod.POST)
public String uploadFileToLocal(HttpServletRequest request) {
MultipartFile file = ((StandardMultipartHttpServletRequest) request).getFile("file");
// 例如可以根据file文件类型判断哪些文件是否可以上传
return super.uploadFileToLocal(request);
}
}在application.yml内配置
cdn:
