本篇文章介绍如何在springboot项目中配置OSS服务，用一个Service类简单实现上传文件与删除文件的操作

步骤

步骤1：创建存储桶

在阿里云OSS创建存储桶

步骤2：创建RAM授权策略

记录AccessKeyId与accessKeySecret，后面会用

步骤3：在项目中添加依赖

            <!-- 阿里云oss存储api -->
            <dependency>
                <groupId>com.aliyun.oss</groupId>
                <artifactId>aliyun-sdk-oss</artifactId>
                <version>${oss.version}</version>
            </dependency>

步骤4：编写接口与实现类

写两个方法

public interface OssService {
    String upload(MultipartFile file, String path);
    boolean delete(String relativePath);
}

@Service
public class OssServiceImpl implements OssService {
    // 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 = "xxx";
    // 阿里云账号AccessKey
    String accessKeyId = "xxx";
    String accessKeySecret = "xxx";
    String bucketName="xxx";
    @Override
    public String upload(MultipartFile file, String path) {
//        ossClint构建
        OSS oss = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
        try {
//            文件转化为字节流上传
            PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName,path,new ByteArrayInputStream(file.getBytes()));
            oss.putObject(putObjectRequest);
        } catch (IOException e) {
            e.printStackTrace();
            return null;
        }finally {
            oss.shutdown();
        }
        return "your link"+path;
    }
    public boolean delete(String relativePath){
        OSS oss = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
        try {
            oss.deleteObject(bucketName,relativePath);
        }catch (Exception e){
            e.printStackTrace();
            return false;
        }finally {
            oss.shutdown();
        }
        return true;
    }
}
