SpringBoot添加阿里云OOS服务

在 pom.xml 文件中添加依赖

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

在配置文件中添加 OSS 配置项

aliyun:
  oss:
      # oss对外服务的访问域名
    endpoint: oss-cn-beijing.aliyuncs.com
      # 访问身份验证中用到用户标识
    accessKeyId: LTAI5
      # 用户用于加密签名字符串和oss用来验证签名字符串的密钥
    accessKeySecret: RYN
      # oss的存储空间
    bucketName: itwanger-oss1
      # 上传文件大小(M)
    maxSize: 3
      # 上传文件夹路径前缀
    dir:
      prefix: codingmore/images/

添加配置类OssClientConfig.java

@Configuration
public class OssClientConfig {
    @Value("${aliyun.oss.endpoint}")
    private String endpoint ;
    @Value("${aliyun.oss.accessKeyId}")
    private String accessKeyId ;
    @Value("${aliyun.oss.accessKeySecret}")
    private String accessKeySecret;

    @Bean
    public OSSClient createOssClient() {
        return (OSSClient)new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
    }
}

上传文件API （Controller）

@RestController
@RequestMapping("/upload")
public class OssController {
    @Autowired
    private OssService ossService;

    @PostMapping("/files")
    public String upload(@RequestParam("file") MultipartFile file, HttpServletRequest req)  {
        return ossService.upload(file);
    }
}

上传文件API （Service）

@Service
public class OssService {
    @Value("${aliyun.oss.maxSize}")
    private int maxSize;
   
    @Value("${aliyun.oss.bucketName}")
    private String bucketName;
  
    @Value("${aliyun.oss.dir.prefix}")
    private String dirPrefix;

 	@Autowired
    private OSSClient ossClient;  
    
    public String upload(MultipartFile file) {
    	String objectName = getBucketName(name);
        // 创建PutObject请求。
        ossClient.putObject(bucketName, objectName,inputStream);
        return formatPath(objectName);
	}
	
	private String getBucketName(String url){
        String ext = "";
        for(String extItem:imageExtension){
            if(url.indexOf(extItem) != -1){
                ext = extItem;
                break;
            }
        }
        return dirPrefix+ DateUtil.today()+"/"+ IdUtil.randomUUID()+ext;
    }

    private String formatPath(String objectName){
        return "https://"  +bucketName+"."+ ossClient.getEndpoint().getHost() + "/" + objectName;
    }
}
