【工具类】使用阿里oss实现图片、视频、文档上传

一、背景描述

功能是想实现图片、视频和文档的上传。

项目技术栈：springboot(2.1.5.RELEASE)

二、引入依赖

    <dependency>
      <groupId>com.aliyun.oss</groupId>
      <artifactId>aliyun-sdk-oss</artifactId>
      <version>2.8.3</version>
    </dependency>

三、配置文件

oss:
  endpoint: http://oss-cn-hangzhou.aliyuncs.com
  accessKeyId: LTAI****Jb
  accessKeySecret: SEglg******iRW
  bucket: shcsoss

以上的配置内容，配置在application.yml文件中，放置在resources目录下。

四、接口实现

package com.iot.productmanual.controller;


import com.iot.framework.core.response.CommResponse;
import com.iot.productmanual.common.enums.ErrorCode;
import com.iot.productmanual.model.vo.Image;
import com.iot.productmanual.service.UploadService;

import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;


/**

@Api(value = "UploadController", tags = "文件上传oss通用")
@RequestMapping("/upload")
@Controller
public class UploadController {

    @Autowired
    private UploadService uploadService;

    @ApiOperation(value = "文件上传")
    @PostMapping("/file")
    @ResponseBody
    public CommResponse uploadFileSample(MultipartFile file) {
        String url = null;
        if (!file.isEmpty()) {
            CommResponse<Image> response = uploadService.uploadFile(file);
            if (response.getCode() != 0){
                return response;
            }
            Image image = response.getData();
            url = image.getSrc();
        }else {
            return CommResponse.fail(ErrorCode.E_420101.getCode(),ErrorCode.E_420101.getDesc());
        }
        return CommResponse.ok(url);
    }

}
