一、申请Bucket

1. 进入该网址对象存储oss述

2. 创建Bucket
   

3. 创建信息
   

4. 文件设置，可以将自己上传的文件根据类型上传不同的文件夹
   

5. 读写权限，弄公共读即可
   

6. 跨域设置
   

7. 域名设置，根据情况也可以添加ssl证书，一般服务器配置里ssl，会自己识别到
   

二、 获取AccessKey ID、AccessKey Secret

1. 点击这里
   
2. 创建AccessKey
   

三、 springboot整合

3.1 在application.yml 配置参数

endpoint这里，在oss管理界面问一下快捷帮助可以弹出

3.2 oss需要的pom

 <!--阿里云文件服务器oss-->
        <dependency>
            <groupId>com.aliyun.oss</groupId>
            <artifactId>aliyun-sdk-oss</artifactId>
            <version>2.8.3</version>
        </dependency>

3.3 配置 oss配置类

package com.seven.server.config.oss;

import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;

/**
 * @Author: Jia Zhenqi
 * @Date: 2023/2/18  15:44
 * @Version 1.0
 */
@Configuration
public class OssConfig implements InitializingBean {

    //读取配置文件的内容
    @Value("${aliyun.oss.file.endpoint}")
    private String endpoint;
    @Value("${aliyun.oss.file.keyid}")
    private String keyId;
    @Value("${aliyun.oss.file.keysecret}")
    private String keySecret;
    @Value("${aliyun.oss.file.bucketname}")
    private String bucketName;

    //定义公共静态常量
    public static String END_POINT;
    public static String ACCESS_KEY_ID;
    public static String ACCESS_KEY_SECRET;
    public static String BUCKET_NAME;

    @Override
    public void afterPropertiesSet() throws Exception {
        END_POINT = endpoint;
        ACCESS_KEY_ID = keyId;
        ACCESS_KEY_SECRET = keySecret;
        BUCKET_NAME = bucketName;
    }
}

3.4 oss的controller类

package com.seven.server.controller;

import com.seven.server.service.OssService;
import com.seven.server.util.result.RespBean;
import io.swagger.annotations.Api;
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;

/**
 * @Author: Jia Zhenqi
 * @Date: 2023/2/18  15:47
 * @Version 1.0
 */
@Api(tags = "oss图片上传接口管理")
@RestController
@RequestMapping("/api/oss")
public class OssController {
    @Autowired
    private OssService ossService;

    /**
     * 调用oss上传文件，返回url
     * @param file
     * @return
     * @throws Exception
     */
    @PostMapping("/upload")
    public RespBean uploadOssFile(MultipartFile file, String path) throws Exception{
        //获取上传文件 MultipartFile
        //返回图片在oss上的路径
        return ossService.uploadFileAvatar(file,path);
    }

}

3.5 oss的service类以及impl

service

package com.seven.server.service;

import com.seven.server.util.result.RespBean;
import org.springframework.web.multipart.MultipartFile;

/**
 * @Author: Jia Zhenqi
 * @Date: 2023/2/18  15:47
 * @Version 1.0
 */
public interface OssService {

    /**
     * 调用oss上传接口
     * @param file
     * @param path
     * @return
     * @throws Exception
     */
    public RespBean uploadFileAvatar(MultipartFile file, String path) throws Exception;
}

serviceimpl

package com.seven.server.service.impl;

import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClient;
import com.seven.server.config.oss.OssConfig;
import com.seven.server.service.OssService;
import com.seven.server.util.result.RespBean;
import com.seven.server.util.uuid.Uuid;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;

import java.io.InputStream;
import java.util.UUID;

/**
 * @Author: Jia Zhenqi
 * @Date: 2023/2/18  15:47
 * @Version 1.0
 */
@Service
public class OssServiceImpl implements OssService {
    /**
     * 调用oss上传接口
     * @param file
     * @param path
     * @return
     * @throws Exception
     */
    @Override
    public RespBean uploadFileAvatar(MultipartFile file, String path)  throws Exception{

        String endpoint = OssConfig.END_POINT;
        String accessKeyId = OssConfig.ACCESS_KEY_ID;
        String accessKeySecret = OssConfig.ACCESS_KEY_SECRET;
        String bucketName = OssConfig.BUCKET_NAME;
        String url = null;

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

        //获取上传文件输入流
        InputStream inputStream = file.getInputStream();
        //获取文件名称
        String fileName = file.getOriginalFilename();

        //保证文件名唯一，去掉uuid中的'-'
        String uuid = Uuid.getUUID();
        fileName = uuid + fileName;

        //拼接
        fileName = path + "/" + fileName;

        //调用oss方法上传到阿里云
        //第一个参数：Bucket名称
        //第二个参数：上传到oss文件路径和文件名称
        //第三个参数：上传文件输入流
        ossClient.putObject(bucketName, fileName, inputStream);

        //把上传后把文件url返回
        //https://xppll.oss-cn-beijing.aliyuncs.com/01.jpg
        url = "https://" + bucketName + "." + endpoint + "/" + fileName;
        //关闭OSSClient
        ossClient.shutdown();

        return RespBean.success("图片上传成功", url);
    }
}
