阿里云OSSClient上传文件

2024年1月12日 30次阅读来源: 權先森和香香

开发中，经常遇到上传文件的需求，下面我就对阿里云OSS做下总结

Controller层：

import javax.servlet.http.HttpServletRequest;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

import com.alibaba.fastjson.JSONObject;

import cn.xiaooo.qingyanxiyu.service.UpImgService;

@CrossOrigin
@RestController
public class UpImgController {

   public static final Logger logger = LoggerFactory.getLogger(UpImgController.class);
   
   @Autowired
   private UpImgService upImgService;
   
   @RequestMapping(value = "/headImgUpload",method = RequestMethod.POST)
   public String headImgUpload(HttpServletRequest request,MultipartFile file) {
      Map<String, Object> value = new HashMap<String, Object>();
      try {
         String url = upImgService.updateHead(file);
         System.out.println(url);
         logger.debug("图片路径:",url);
         value.put("data", url);
         value.put("code", 0); 
         value.put("msg", "图片上传成功");
      } catch (Exception e) {
         value.put("code", 2000);
         value.put("msg", "图片上传失败");
      }
      return JSONObject.toJSONString(value);
   }
   
   @RequestMapping(value = "/UploadVideo",method = RequestMethod.POST)
   public String UploadVideo(HttpServletRequest request,MultipartFile file) {
      Map<String, Object> value = new HashMap<String, Object>();
      try {
         String url = upImgService.updateVideo(file);
         System.out.println(url);
         logger.debug("视频路径:",url);
         value.put("data", url);
         value.put("code", 0); 
         value.put("msg", "视频上传成功");
      } catch (Exception e) {
         value.put("code", 2000);
         value.put("msg", "视频上传失败");
      }
      return JSONObject.toJSONString(value);
   }
}

Service层：

import org.springframework.web.multipart.MultipartFile;

import cn.xiaooo.qingyanxiyu.util.ImgException;

public interface UpImgService {

   String updateHead(MultipartFile file)throws ImgException;
   
   String updateVideo(MultipartFile file)throws ImgException;
}

实现类：

import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;

import cn.xiaooo.qingyanxiyu.util.ImgException;
import cn.xiaooo.qingyanxiyu.util.OSSClientUtil;

@Service
public class UpImgServiceImpl implements UpImgService {

   @Override
   public String updateHead(MultipartFile file) throws ImgException {
       if (file == null || file.getSize() <= 0) {
          throw new ImgException("file不能为空");
          }         
       OSSClientUtil ossClient=new OSSClientUtil();
       String name = ossClient.uploadImg2Oss(file);
       String imgUrl = ossClient.getImgUrl(name);
       String[] split = imgUrl.split("\\?");
       return split[0];
   }
   
   @Override
   public String updateVideo(MultipartFile file) throws ImgException {
       if (file == null || file.getSize() <= 0) {
          throw new ImgException("file不能为空");
          }         
       OSSClientUtil ossClient=new OSSClientUtil();
       String name = ossClient.uploadResource(file);
       String imgUrl = ossClient.getImgUrl(name);
       String[] split = imgUrl.split("\\?");
       return split[0];
   }
}

视频格式可以自己进行修改
