阿里OSS

新建一个properties 永远存储阿里OSS的配置文件信息
因为bucket是可读不可写的当需要获取岛文件路径时直接使用host字段 + 文件路径即可读取文件信息
objectname 用于存储文件

aliyun.oss.endpoint = oss-cn-beijing.aliyuncs.com
aliyun.oss.bucket = lyra-news
aliyun.oss.objectname = images/
aliyun.oss.host = test

和之前一样读取配置我二级

@PropertySource("classpath:aliOSS.properties")
@Component
@ConfigurationProperties(prefix = "aliyun.oss")
public class AliyunOSSResources {
    private String endpoint;
    private String bucket;
    private String objectname;
    private String host;


    public String getEndpoint() {
        return endpoint;
    }

    public void setEndpoint(String endpoint) {
        this.endpoint = endpoint;
    }

    public String getBucket() {
        return bucket;
    }

    public void setBucket(String bucket) {
        this.bucket = bucket;
    }

    public String getObjectname() {
        return objectname;
    }

    public void setObjectname(String objectname) {
        this.objectname = objectname;
    }

    public String getHost() {
        return host;
    }

    public void setHost(String host) {
        this.host = host;
    }
}

根据API文档写配置工具类返回时将路径和host拼接返回名称

@Component
public class AliOSSUtils {
    @Autowired
    private AliyunOSSResources aliyunOSSResources;

    @Autowired
    private AliyunResources aliyunResources;

    public String uploadFile(InputStream fileInputStream, String uploadPathAndFileName) {
        // yourEndpoint填写Bucket所在地域对应的Endpoint。以华东1（杭州）为例，Endpoint填写为https://oss-cn-hangzhou.aliyuncs.com。
        String endpoint = aliyunOSSResources.getEndpoint();
    // 阿里云账号AccessKey拥有所有API的访问权限，风险很高。强烈建议您创建并使用RAM用户进行API访问或日常运维，请登录RAM控制台创建RAM用户。
        String accessKeyId = aliyunResources.getAccessKeyId();
        String accessKeySecret = aliyunResources.getAccessKeySecret();

    // 创建OSSClient实例。
        OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);

    // 依次填写Bucket名称（例如examplebucket）和Object完整路径（例如exampledir/exampleobject.txt）。Object完整路径中不能包含Bucket名称。
        ossClient.putObject(aliyunOSSResources.getBucket(), uploadPathAndFileName, fileInputStream);

    // 关闭OSSClient。
        ossClient.shutdown();



        return aliyunOSSResources.getHost() + "/" + uploadPathAndFileName;
    }
}

避免文件重复使用uuid来进行命名并将后缀拼接

    public String uploadFileOfOSS(MultipartFile multipartFile, String userId) throws IOException {
        String fileName = multipartFile.getOriginalFilename();

        if (StringUtils.isNotBlank(fileName) && StringUtils.isNotBlank(userId)) {
            String suffix = fileName.substring(fileName.lastIndexOf("."));

            String filePathAndFileName = userId + "/" + UUID.randomUUID().toString() + suffix;


            return aliOSSUtils.uploadFile(multipartFile.getInputStream(), filePathAndFileName);
        } else {
            GraceException.display(ResponseStatusEnum.FILE_UPLOAD_NULL_ERROR);

            return null;
        }
    }
