【Spring Boot 19】Spring Boot 整合阿里云 OSS 实现云存储
2、工具类
package com.atguigu.oss.utils;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
//当项目已启动,spring 接口,spring 加载之后,执行接口一个方法
@Component
public class ConstantPropertiesUtils implements InitializingBean {
//读取配置文件内容
@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;
//定义公开静态常量
public static String END_POIND
;
public static String ACCESS_KEY_ID;
public static String ACCESS_KEY_SECRET;
public static String BUCKET_NAME;
@Override
public void afterPropertiesSet() throws Exception {
END_POIND = endpoint;
ACCESS_KEY_ID = keyId;
ACCESS_KEY_SECRET = keySecret;
BUCKET_NAME = bucketName;
}
}
3、service
接口
package com.atguigu.oss.service;
import org.springframework.web.multipart.MultipartFile;
public interface OssService {
String uploadFileAvatar(MultipartFile file);
}
实现类
package com.atguigu.oss.service.impl;
import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import com.atguigu.oss.service.OssService;
import com.atguigu.oss.utils.ConstantPropertiesUtils;
import org.joda.time.DateTime;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;
import java.io.InputStream;
import java.util.UUID;
@Service
public class OssServiceImpl implements OssService {
//上传头像到 oss
@Override
public String uploadFileAvatar(MultipartFile file) {
// 工具类获取值
String endpoint = ConstantPropertiesUtils.END_POIND;
String accessKeyId = ConstantPropertiesUtils.ACCESS_KEY_ID;
String accessKeySecret = ConstantPropertiesUtils.ACCESS_KEY_SECRET;
String bucketName = ConstantPropertiesUtils.BUCKET_NAME;
try {
// 创建 OSS 实例。
OSS ossClient = new OSSClientBuilder().build(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();
//1 在文件名称里面添加随机唯一的值
String uuid = UUID.randomUUID().toString().replaceAll("-","");
// yuy76t5rew01.jpg
fileName = uuid+fileName;
//2 把文件按照日期进行分类
//获取当前日期
// 2019/11/12
String datePath = new DateTime().toString("yyyy/MM/dd");
//拼接
// 2019/11/12/ewtqr313401.jpg
fileName = datePath+"/"+fileName;
//调用 oss 方法实现上传
//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 aa/bb/1.jpg
//第三个参数 上传文件输入流
ossClient.putObject(bucketName,fileName , inputStream);
// 关闭 OSSClient。
ossClient.shutdown();
//把上传之后文件路径返回
//需要把上传到阿里云 oss 路径手动拼接出来
// https://edu-guli-1010.oss-cn-beijing.aliyuncs.com/01.jpg
String url = "https://"+bucketName+"."+endpoint+"/"+fileName;
return url;
}catch(Exception e) {
e.printStackTrace();
return null;
}
}
}
4、controller
package com.atguigu.oss.controller;
import com.atguigu.oss.service.OssService;
