springBoot接入阿里云oss的实现步骤

maven导入依赖

<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.15</version> </dependency> <dependency> <groupId>commons-lang</groupId> <artifactId>commons-lang</artifactId> <version>2.6</version> </dependency> <!-- 阿里云OSS --> <dependency> <groupId>com.aliyun.oss</groupId> <artifactId>aliyun-sdk-oss</artifactId> <version>3.10.2</version> </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 */@Datapublic 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;@Componentpublic 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); }}
