阿里云 OSS 对象存储服务

1. 1、首先导入阿里云oss sdk 依赖

   <!--阿里oss sdk-->
   <dependency>
       <groupId>com.aliyun.oss</groupId>
       <artifactId>aliyun-sdk-oss</artifactId>
       <version>3.17.2</version>
   </dependency>

    

2. 2、创建controller

   @ApiOperation(value = "文件上传")
   @PostMapping("/uploadFile")
   public CommonResult<UploadFileDto> uploadFile(@RequestParam("file") MultipartFile file,@RequestParam(value = "fileType",required = false)Integer fileType,@RequestParam(value = "fileName",required = false)String fileName) throws Exception {
       // 上传至阿里云
       return uploadFileService.singleFileUpload(file,fileType,fileName);
   }

    

3. 3、service

   /**
    * 阿里云oss文件上传
    *
    * @author yubin
    * @date 2024/4/2 16:08
    * @param file 文件
    * @param fileType 文件类型
    * @param fileName 文件名称
    * @return com.xinwei.olden.common.CommonResult<com.xinwei.olden.dto.UploadFileDto>
    */
   CommonResult<UploadFileDto> singleFileUpload(MultipartFile file, Integer fileType, String fileName);

    

4. 4、实现类

   /**
    * 阿里云oss文件上传
    *
    * @author yubin
    * @date 2024/4/2 16:08
    * @param file 文件
    * @param fileType 文件类型
    * @param fileName 文件名称
    * @return com.xinwei.olden.common.CommonResult<com.xinwei.olden.dto.UploadFileDto>
    */
   CommonResult<UploadFileDto> singleFileUpload(MultipartFile file, Integer fileType, String fileName);

    

5. 5、以及自己封装的工具类

   package com.xinwei.olden.util;
    
   import com.baomidou.mybatisplus.core.toolkit.StringUtils;
   import com.xinwei.olden.dto.UploadFileDto;
   import com.xinwei.olden.service.UploadFileService;
   import com.xinwei.olden.vo.TeacherCertFileVo;
   import com.xinwei.olden.vo.UploadFileVo;
   import com.xinwei.olden.vo.req.FileZipReqVo;
   import lombok.Data;
   import org.apache.commons.io.FilenameUtils;
   import org.apache.commons.io.IOUtils;
   import org.springframework.beans.factory.annotation.Autowired;
   import org.springframework.beans.factory.annotation.Value;
   import org.springframework.boot.context.properties.ConfigurationProperties;
   import org.springframework.stereotype.Component;
   import org.springframework.web.multipart.MultipartFile;
   import javax.annotation.PostConstruct;
   import javax.servlet.ServletOutputStream;
   import javax.servlet.http.HttpServletResponse;
   import java.io.*;
   import java.net.HttpURLConnection;
   import java.net.URL;
   import java.net.URLEncoder;
   import java.time.LocalDateTime;
   import java.util.*;
   import java.util.zip.ZipEntry;
   import java.util.zip.ZipOutputStream;
    
   /**
    * 文件上传工具类
    *
    * @author yubin
    * @date 2023/11/23 17:19
    */
   @Component
   @Data
   @ConfigurationProperties(prefix = "upload")
   public class UploadUtils {
    
       
    
       /**
        * 验证图片格式是否允许上传
        *
        * @author yubin
        * @date 2023/11/24 10:37
        * @param targetValue 目标文件格式
        * @return boolean
        */
       public static boolean img_check(String targetValue) {
           String[] arr = new String[]{".jpg", ".jpeg", ".png", ".gif"};
           return Arrays.asList(arr).contains(targetValue);
       }
    
       /**
        * 验证文件格式是否允许上传
        *
        * @author yubin
        * @date 2023/11/24 10:37
        * @param targetValue 目标文件格式
        * @return boolean
        */
       public static boolean doc_check(String targetValue) {
           String[] arr = new String[]{".doc", ".pdf", ".docx", ".xlsx", ".xls"};
           return Arrays.asList(arr).contains(targetValue);
       }
    
   }

    

6. 6、阿里oss配置类，放置阿里云oss服务器具体的配置参数

   package com.xinwei.olden.constant;
    
   import com.aliyun.oss.OSS;
   import com.aliyun.oss.OSSClientBuilder;
   import lombok.Data;
   import org.springframework.beans.factory.annotation.Value;
   import org.springframework.context.annotation.Bean;
   import org.springframework.context.annotation.Configuration;
    
   /**
    * OSS 阿里oss配置
    *
    * @author yubin
    * @date 2024/4/2 15:44
    */
   @Configuration
   @Data
   public class OssConfig {
    
       @Value("${oss.accessKeyId}")
       private String accessKeyId;
    
       @Value("${oss.accessKeySecret}")
       private String accessKeySecret;
    
       @Value("${oss.endPoint}")
       private String endPoint;
    
       @Value("${oss.bucketName}")
       private String bucketName;
    
       @Value("${oss.domain}")
       private String domain;
    
       @Bean
       public OSS getOssClient() {
           return new OSSClientBuilder().build(endPoint, accessKeyId, accessKeySecret);
       }
    
   }

    

7. 7、我部署的是springboot2.7.5项目，单机版的所有配置都写在application-dev.yml里

   oss:
     accessKeyId: oss的accessKeyId
     accessKeySecret: oss的accessKeySecret
     endPoint: 自己购买的服务器域名
     bucketName: 阿里云桶名称
     domain: 阿里云oss地址

    

以上都弄好后，接口上传文件至阿里云服务器
