配置第三方bean

/**
 * 配置类用于创建AliOssUtil对象
 */
@Slf4j
@Configuration
public class OssConfiguration {
    @Bean//将方法返回值交给IOC容器管理，成为IOC容器的bean对象
    @ConditionalOnMissingBean//只创建一个bean对象
    public AliOssUtil aliOssUtil(AliOssProperties aliOssProperties){
        log.info("开始创建阿里云文件上传工具类对象：{}",aliOssProperties);
        return new AliOssUtil(aliOssProperties.getEndpoint(),
                aliOssProperties.getAccessKeyId(),
                aliOssProperties.getAccessKeySecret(),
                aliOssProperties.getBucketName());
    }



}

在application.yml中通过引用dev开发环境下的配置文件配置存储服务器

sky:
  jwt:
    # 设置jwt签名加密时使用的秘钥
    admin-secret-key: itcast
    # 设置jwt过期时间
    admin-ttl: 720000000
    # 设置前端传递过来的令牌名称
    admin-token-name: token
  alioss:
    accessKeyId: ${sky.alioss.accessKeyId}
    accessKeySecret: ${sky.alioss.accessKeySecret}
    bucketName: ${sky.alioss.bucketName}
    endpoint: ${sky.alioss.endpoint}
- application-dev.yml
sky:

      accessKeySecret: gyNxSnYFo9IsHi2BRwcgxTOrcYIS15
      bucketName: hmc-webframework01
      endpoint: https://oss-cn-beijing.aliyuncs.com

创建配置类

@Component
@ConfigurationProperties(prefix = "sky.alioss")
@Data
public class AliOssProperties {

    private String endpoint;
    private String accessKeyId;
    private String accessKeySecret;
    private String bucketName;


}

引入工具类

@Data
@AllArgsConstructor
@Slf4j
public class AliOssUtil {

    private String endpoint;
    private String accessKeyId;
    private String accessKeySecret;
    private String bucketName;

    /**
     * 文件上传
     *
     * @param bytes
     * @param objectName
     * @return
     */
    public String upload(byte[] bytes, String objectName) {

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

        try {
            // 创建PutObject请求。
            ossClient.putObject(bucketName, objectName, new ByteArrayInputStream(bytes));
        } catch (OSSException oe) {
            System.out.println("Caught an OSSException, which means your request made it to OSS, "
                    + "but was rejected with an error response for some reason.");
            System.out.println("Error Message:" + oe.getErrorMessage());
            System.out.println("Error Code:" + oe.getErrorCode());
            System.out.println("Request ID:" + oe.getRequestId());
            System.out.println("Host ID:" + oe.getHostId());
        } catch (ClientException ce) {
            System.out.println("Caught an ClientException, which means the client encountered "
                    + "a serious internal problem while trying to communicate with OSS, "
                    + "such as not being able to access the network.");
            System.out.println("Error Message:" + ce.getMessage());
        } finally {
            if (ossClient != null) {
                ossClient.shutdown();
            }
        }

        //文件访问路径规则 https://BucketName.Endpoint/ObjectName
        StringBuilder stringBuilder = new StringBuilder("https://");
        stringBuilder
                .append(bucketName)
                .append(".")
                .append(endpoint)
                .append("/")
                .append(objectName);

        log.info("文件上传到:{}", stringBuilder.toString());

        return stringBuilder.toString();
    }
}

创建公共接口

/**
 * 通用接口
 */
@Slf4j
@RestController
@Api(tags = "通用接口")
@RequestMapping("/admin/common")
public class CommonController {
    @Autowired
    private AliOssUtil aliOssUtil;

    /**
     * 文件上传
     * @param file
     * @return
     */
    @ApiOperation("文件上传")
    @PostMapping("/upload")
    public Result<String>upload(MultipartFile file){
      log.info("文件上传{}",file);
        try {
            //原始文件名
            String originalFilename= file.getOriginalFilename();
            //截取扩展名
           String extension= originalFilename.substring(originalFilename.lastIndexOf("."));
           String objectName= UUID.randomUUID().toString()+extension;
          String filePath=  aliOssUtil.upload(file.getBytes(), objectName);
            return Result.success(filePath);
        } catch (IOException e) {
            log.error("文件上传失败: {}",e);
        }
        return Result.error(MessageConstant.UPLOAD_FAILED);
    }

}
