SpringBoot添加阿里云OOS服务

在 pom.xml 在文件中添加依赖

<dependency>     <groupId>com.aliyun.ossgroupId>     <artifactId>aliyun-sdk-ossartifactId>     <version>x.x.xversion> dependency> 

添加到配置文件中 OSS 配置项

aliyun:   oss:       # oss访问域名的外部服务     endpoint: oss-cn-beijing.aliyuncs.com       # 用户标识用于访问身份验证     accessKeyId: LTAI5       # 用户用于加密签名字符串和oss密钥用于验证签名字符串     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;
    }
}
