这篇文章主要介绍了springBoot接入阿里云oss的实现步骤，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧
maven导入依赖

<!-- 阿里云OSS -->
<dependency>
<groupId>com.aliyun.oss</groupId>
<artifactId>aliyun-sdk-oss</artifactId>

</dependency>
</dependencies>
定义阿里云上传结果实体
package com.example.demo.entity;
import lombok.Data;
/**
* 阿里云上传结果集
*
* @author wushuai
* @create 2021-01-25
*/
@Data
public class AliyunOssResult {
/**
* code：200成功
* code: 400失败
*/
private int code;
/**
* 上传成功的返回url
*/
private String url;
/**
* 提示信息
*/
private String msg;
}
yml设置阿里云oss参数
aliyunOss: endpoint: "http://oss-cn-shanghai.aliyuncs.com" accessKeyId: "xxxxxxx" accessKeySecret: "xxxxxxx" bucketName: "xxxxxx" urlPrefix: "http://bucketName.oss-cn-shanghai.aliyuncs.com/"
yml设置上传文件大小限制
spring: servlet: multipart: max-file-size: 20MB max-request-size: 20MB
工具类封装
package com.example.demo.util;
import com.aliyun.oss.OSS;
import com.aliyun.oss.OSSClientBuilder;
import com.aliyun.oss.model.DeleteObjectsRequest;
import com.aliyun.oss.model.DeleteObjectsResult;
import com.aliyun.oss.model.GeneratePresignedUrlRequest;
import com.example.demo.entity.AliyunOssResult;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import java.io.InputStream;
import java.net.URL;
import java.util.Date;
import java.util.List;
@Component
public class AliyunOSSUtil {
@Value("${aliyunOss.endpoint}")
private String endpoint;
@Value("${aliyunOss.accessKeyId}")
private String accessKeyId;
@Value("${aliyunOss.accessKeySecret}")
private String accessKeySecret;
@Value("${aliyunOss.bucketName}")
private String bucketName;
@Value("${aliyunOss.urlPrefix}")
private String urlPrefix;
/**
* 上传文件，以IO流方式
*
* @param inputStream 输入流
* @param objectName 唯一objectName（在oss中的文件名字）
*/
public AliyunOssResult upload(InputStream inputStream, String objectName) {
AliyunOssResult aliyunOssResult = new AliyunOssResult();
try {
// 创建OSSClient实例。
OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
// 上传内容到指定的存储空间（bucketName）并保存为指定的文件名称（objectName）。
ossClient.putObject(bucketName, objectName, inputStream);
// 关闭OSSClient。
ossClient.shutdown();
aliyunOssResult.setCode(200);
aliyunOssResult.setUrl(urlPrefix+objectName);
aliyunOssResult.setMsg("上传成功");
} catch (Exception e) {
e.printStackTrace();
aliyunOssResult.setCode(400);
aliyunOssResult.setMsg("上传失败");
}
return aliyunOssResult;
}
/**
* 删除OSS中的单个文件
*
* @param objectName 唯一objectName（在oss中的文件名字）
*/
public void delete(String objectName) {
try {
// 创建OSSClient实例。
OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
// 删除文件。
ossClient.deleteObject(bucketName, objectName);
// 关闭OSSClient。
ossClient.shutdown();
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* 批量删除OSS中的文件
*
* @param objectNames oss中文件名list
*/
public void delete(List<String> objectNames) {
try {
// 创建OSSClient实例。
OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
// 批量删除文件。
DeleteObjectsResult deleteObjectsResult = ossClient.deleteObjects(new DeleteObjectsRequest(bucketName).withKeys(objectNames));
List<String> deletedObjects = deleteObjectsResult.getDeletedObjects();
// 关闭OSSClient。
ossClient.shutdown();
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* 获取文件临时url
*
* @param objectName oss中的文件名
* @param effectiveTime 有效时间(ms)
*/
public String getUrl(String objectName,long effectiveTime){
OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
// 设置URL过期时间
Date expiration = new Date(new Date().getTime() + effectiveTime);
GeneratePresignedUrlRequest generatePresignedUrlRequest ;
generatePresignedUrlRequest =new GeneratePresignedUrlRequest(bucketName, objectName);
generatePresignedUrlRequest.setExpiration(expiration);
URL url = ossClient.generatePresignedUrl(generatePresignedUrlRequest);
return url.toString();
}
}
controller接收调用
package com.example.demo.controller;
import com.example.demo.util.AliyunOSSUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import java.io.IOException;
import java.util.UUID;
@RestController
@RequestMapping("/file")
public class FileController {
@Autowired
private AliyunOSSUtil aliyunOSSUtil;
@RequestMapping(value = "/uploadFile")
public @ResponseBody
Object uploadFile(@RequestParam(value = "file", required = false) MultipartFile file,
String strPath) throws IOException {
String suffix = file.getOriginalFilename().substring(file.getOriginalFilename().lastIndexOf(".") + 1);
String objectName = strPath+"/"+ UUID.randomUUID().toString()+"."+suffix;
return aliyunOSSUtil.upload(file.getInputStream(),objectName);
}
}
postman测试
