> 不讲别的，直接看代码

## 准备 ##

AccessKey：访问密钥  
SecretKey：访问密钥  
endPoint：终端节点  
bucketName：桶

## 1 添加maven依赖 ##

<dependency>
        <groupId>com.huaweicloud</groupId>
        <artifactId>esdk-obs-java</artifactId>
        <version>3.19.7</version>
    </dependency>

## 2 添加obs的配置信息 ##

# huawei ods
    huawei.obs.ak=hajkfhdsajkhjdkahsfjs
    huawei.obs.sk=hjaksjfhdakdfhajkfhdsajkhjdkahsfjsadhaljkhdfsd
    # 上传的endPoint
    huawei.obs.upload.endPoint=endPoint.com
    # 访问的endPoint
    huawei.obs.access.endPoint=https://endPoint.com
    # 桶
    huawei.obs.bucketName=obs-bucket-dev

## 3 配置obs ##

import com.obs.services.ObsClient;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    @Configuration
    public class ObsConfig {
    
        @Value("${huawei.obs.ak}")
        private String ak;
    
        @Value("${huawei.obs.sk}")
        private String sk;
    
        @Value("${huawei.obs.upload.endPoint}")
        private String endPoint;
    
        @Bean
        public ObsClient getObsClient(){
            ObsClient obsClient = new ObsClient(ak, sk, endPoint);
            return obsClient;
        }
    }

## 4 创建obs工具类，提供上传和删除功能 ##

import com.obs.services.ObsClient;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.stereotype.Component;
    import org.springframework.web.multipart.MultipartFile;
    
    import java.io.InputStream;
    
    @Component
    public class ObsUtil {
    
        @Autowired
        private ObsClient obsClient;
    
        @Value("${huawei.obs.bucketName}")
        private String bucketName;
    
        //上传文件，multipartFile就是你要的文件，
        //objectKey就是文件名，如果桶中有文件夹的话，如往test文件上传test.txt文件，那么objectKey就是test/test.txt
        public void uploadFile(MultipartFile multipartFile, String objectKey) throws Exception{
            InputStream inputStream = multipartFile.getInputStream();
            obsClient.putObject(bucketName, objectKey, inputStream);
            inputStream.close();
            obsClient.close();
        }
        public void deleteFile(String objectKey) throws Exception{
            obsClient.deleteObject(bucketName, objectKey);
            obsClient.close();
        }
    }
