1、进入阿里云官网

https://www.aliyun.com/

2、搜索“对象存储OSS”

3、进入“管理控制台”

4、进入“Bucket列表”，点击“创建Bucket”

5、根据实际情况选择，最后点击“确定”

这里插入一个可以通过代码创建Bucket的测试类，如下：

import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;public class OssTest {public static void main(String[] args) {String endpoint = "https://oss-cn-shanghai.aliyuncs.com";String accessKeyId = "LTAI5tRo9YESJJp2EjPscF1h";String accessKeySecret = "UhClPCgctvM0gZdcppsCc0vTMOVuKm";String bucketName = "sgg-yygh-syt-test";//创建OSSClient实例OSS ossClient = new OSSClientBuilder().build(endpoint,accessKeyId,accessKeySecret);//创建存储空间ossClient.createBucket(bucketName);//关闭OSSClientossClient.shutdown();}
}

6、点击“文件列表”，选择“上传文件”

7、选择“扫描文件”，顺便选择一张图片后，再点击“上传文件”

8、返回文件列表，点击“详情”

9、复制url，粘贴到浏览器上就可以下载此文件了

以上均为控制台操作文件，下面展示通过代码操作

10、选择“AccessKey管理”

11、点击“创建AccessKey”

12、创建成功后，把“AccessKey ID”和“AccessKey Secret”复制下来，后面要用

13、开始代码开发，引入依赖，如果是SpringBoot项目就不用加nacos依赖

com.aliyun.ossaliyun-sdk-oss3.15.1

joda-timejoda-time2.10.1
        
com.alibaba.cloudspring-cloud-starter-alibaba-nacos-discovery2.2.0.RELEASE

14、添加配置文件application.properties，SpringBoot项目就不用加nacos的配置了

# 服务端口
server.port=8205
# 服务名
spring.application.name=service-oss#返回json的全局时间格式.
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8# nacos服务地址
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848aliyun.oss.endpoint=oss-cn-shanghai.aliyuncs.com
aliyun.oss.accessKeyId=LTAI5tRo9YESJJp2EjPscF1h
aliyun.oss.secret=UhClPCgctvM0gZdcppsCc0vTMOVuKm
aliyun.oss.bucket=sgg-yygh-syt

aliyun.oss.accessKeyId=LTAI5tRo9YESJJp2EjPscF1h
aliyun.oss.secret=UhClPCgctvM0gZdcppsCc0vTMOVuKm

aliyun.oss.endpoint=oss-cn-shanghai.aliyuncs.com

aliyun.oss.bucket=sgg-yygh-syt

15、添加启动类，SpringBootApplication的

(exclude=DataSourceAutoConfiguration.class)

和EnableDiscoveryClient注解看情况加

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)//取消数据源自动配置
@EnableDiscoveryClient//开启nacos注册中心
@ComponentScan(basePackages = {"com.hospital"})//可以扫描到另一个模块的swagger
public class ServiceOssApplication {public static void main(String[] args) {SpringApplication.run(ServiceOssApplication.class, args);}
}

16、创建ConstantOssPropertiesUtils配置类

import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;@Component
public class ConstantOssPropertiesUtils implements InitializingBean {@Value("${aliyun.oss.endpoint}")private String endpoint;@Value("${aliyun.oss.accessKeyId}")private String accessKeyId;@Value("${aliyun.oss.secret}")private String secret;@Value("${aliyun.oss.bucket}")private String bucket;public static String EDNPOINT;public static String ACCESS_KEY_ID;public static String SECRECT;public static String BUCKET;@Overridepublic void afterPropertiesSet() throws Exception {EDNPOINT=endpoint;ACCESS_KEY_ID=accessKeyId;SECRECT=secret;BUCKET=bucket;}
}

17、编写controller，service，serviceImpl

controller层：

import com.hospital.common.result.Result;
import com.hospital.oss.service.FileService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;@RestController
@RequestMapping("/api/oss/file")
public class FileApiController {@Autowiredprivate FileService fileService;@PostMapping("/fileUpload")public Result fileUpload(MultipartFile file){//获取上传文件String url = fileService.uploadFile(file);return Result.ok(url);}
}

service层：

import org.springframework.web.multipart.MultipartFile;public interface FileService {//上传文件到阿里云ossString uploadFile(MultipartFile file);
}

serviceImpl层：

import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import com.hospital.oss.service.FileService;
import com.hospital.oss.utils.ConstantOssPropertiesUtils;
import org.joda.time.DateTime;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;import java.io.IOException;
import java.io.InputStream;
import java.util.UUID;@Service
public class FileServiceImpl implements FileService {@Overridepublic String uploadFile(MultipartFile file) {//获取ConstantOssPropertiesUtils中的属性String endpoint = ConstantOssPropertiesUtils.EDNPOINT;String accessKeyId = ConstantOssPropertiesUtils.ACCESS_KEY_ID;String accessKeySecret = ConstantOssPropertiesUtils.SECRECT;String bucketName = ConstantOssPropertiesUtils.BUCKET;try {//创建OSSClient实例OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);//上传文件流InputStream inputStream = file.getInputStream();String fileName = file.getOriginalFilename();//生成随机唯一值，使用uuid，添加到文件名称里面String uuid = UUID.randomUUID().toString().replaceAll("-","");fileName = uuid+fileName;//按照当前日期，创建文件夹，上传到创建文件夹里面//2021/02/02/01.jpgString timeUrl = new DateTime().toString("yyyy/MM/dd");fileName = timeUrl+"/"+fileName;//调用方法实现上传ossClient.putObject(bucketName, fileName, inputStream);//关闭OSSClient。ossClient.shutdown();//上传之后文件路径//https://yygh-atguigu.oss-cn-beijing.aliyuncs.com/01.jpgString url = "https://"+bucketName+"."+endpoint+"/"+fileName;//返回return url;} catch (IOException e) {e.printStackTrace();return null;}}
}

18、swagger上传文件测试

19、打开阿里云OSS文件列表查看

最后， 整合阿里云OSS对象存储服务成功！！！
