今天来整合一下SpringBoot和阿里云OSS对象存储服务。
一、配置OSS服务
先在阿里云开通对象存储服务，拿到AccessKeyId、AccessKeySecret。
创建你的bucket(存储空间)，相当于一个一个的文件夹目录。按业务需求分类存储你的文件，图片，音频，app包等等。创建bucket是要选择该bucket的权限，私有，公共读，公共读写，按需求选择。创建bucket时对应的endpoint要记住，上传文件需要用到。
可以配置bucket的生命周期，比如说某些文件有过期时间的，可以配置一下。
二、代码实现
引入依赖包
com.aliyun.oss aliyun-sdk-oss2.8.3
配置文件application.yml
aliyun-oss: #bucket名称 bucketApp: xxx-app domainApp: https://xxx-app.oss-cn-shenzhen.aliyuncs.com/ region: oss-cn-shenzhen endpoint : https://oss-cn-shenzhen.aliyuncs.com accessKeyId: 你的accessKeyId accessKeySecret: 你的accessKeySecret
对应上面配置文件的properties类
package com.example.file.config;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Component
@ConfigurationProperties(prefix = "aliyun-oss")
@Data
public class AliyunOSSProperties {
private String region;
private String endpoint;
private String accessKeyId;
private String accessKeySecret;
private String bucketApp;
private String domainApp;
}
上传文件工具类
package com.example.file.utils;
import com.aliyun.oss.OSSClient;
import com.aliyun.oss.OSSException;
import com.aliyun.oss.model.Objectmetadata;
import com.aliyun.oss.model.PutObjectResult;
import com.example.common.exception.BusinessErrorCode;
import com.example.common.exception.BusinessException;
import com.example.common.utils.FileIdUtils;
import com.example.file.config.AliyunOSSProperties;
import com.example.file.config.FileTypeEnum;
import org.apache.commons.lang3.StringUtils;
import org.apache.commons.lang3.Validate;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.multipart.MultipartFile;
import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;
@Component
public class AliyunOSSUtil {
@Autowired
private AliyunOSSProperties aliyunOSSProperties;
private static Logger logger = LoggerFactory.getLogger(AliyunOSSUtil.class);
private final String NO_SUCH_KEY = "NoSuchKey";
private final String NO_SUCH_BUCKET = "NoSuchBucket";
public List uploadFile(MultipartFile[] files, FileTypeEnum fileTypeEnum, String bucketName, String storagePath, String prefix) {
//创建OSSClient实例
OSSClient ossClient = new OSSClient(aliyunOSSProperties.getEndpoint(), aliyunOSSProperties.getAccessKeyId(), aliyunOSSProperties.getAccessKeySecret());
List fileIds = new ArrayList<>();
try {
for (MultipartFile file : files) {
//创建一个唯一的文件名，类似于id，就是保存在OSS服务器上文件的文件名(自定义文件名)
String fileName = FileIdUtils.creater(fileTypeEnum.getCode());
InputStream inputStream = file.getInputStream();
Objectmetadata objectmetadata = new Objectmetadata();
//设置数据流里有多少个字节可以读取
objectmetadata.setContentLength(inputStream.available());
objectmetadata.setCacheControl("no-cache");
objectmetadata.setHeader("Pragma", "no-cache");
objectmetadata.setContentType(file.getContentType());
objectmetadata.setContentDisposition("inline;filename=" + fileName);
fileName = StringUtils.isNotBlank(storagePath) ? storagePath + "/" + fileName : fileName;
//上传文件
PutObjectResult result = ossClient.putObject(bucketName, fileName, inputStream, objectmetadata);
logger.info("Aliyun OSS AliyunOSSUtil.uploadFileToAliyunOSS,result:{}", result);
fileIds.add(prefix + fileName);
}
} catch (IOException e) {
logger.error("Aliyun OSS AliyunOSSUtil.uploadFileToAliyunOSS fail,reason:{}", e);
} finally {
ossClient.shutdown();
}
return fileIds;
}
public void deleteFile(String fileName, String bucketName) {
OSSClient ossClient = new OSSClient(aliyunOSSProperties.getEndpoint(), aliyunOSSProperties.getAccessKeyId(), aliyunOSSProperties.getAccessKeySecret());
ossClient.deleteObject(bucketName, fileName);
shutdown(ossClient);
}
public void delImg(String imgUrl, String bucketName) {
if (StringUtils.isBlank(imgUrl)) {
return;
}
//问号
int index = imgUrl.indexOf('?');
if (index != -1) {
imgUrl = imgUrl.substring(0, index);
}
int slashIndex = imgUrl.lastIndexOf('/');
String fileId = imgUrl.substring(slashIndex + 1);
OSSClient ossClient = new OSSClient(aliyunOSSProperties.getEndpoint(), aliyunOSSProperties.getAccessKeyId(), aliyunOSSProperties.getAccessKeySecret());
ossClient.deleteObject(bucketName, fileId);
shutdown(ossClient);
}
public boolean doesObjectExist(String fileName, String bucketName) {
Validate.notEmpty(fileName, "fileName can be not empty");
Validate.notEmpty(bucketName, "bucketName can be not empty");
OSSClient ossClient = new OSSClient(aliyunOSSProperties.getEndpoint(), aliyunOSSProperties.getAccessKeyId(), aliyunOSSProperties.getAccessKeySecret());
try {
boolean found = ossClient.doesObjectExist(bucketName, fileName);
return found;
} finally {
shutdown(ossClient);
}
}
public void ossCopyObject(String fileName, String bucketName, String destinationBucketName, String destinationObjectName) {
Validate.notEmpty(fileName, "fileName can be not empty");
Validate.notEmpty(bucketName, "bucketName can be not empty");
Validate.notEmpty(destinationBucketName, "destinationBucketName can be not empty");
Validate.notEmpty(destinationObjectName, "destinationObjectName can be not empty");
OSSClient ossClient = new OSSClient(aliyunOSSProperties.getEndpoint(), aliyunOSSProperties.getAccessKeyId(), aliyunOSSProperties.getAccessKeySecret());
// 拷贝文件。
try {
ossClient.copyObject(bucketName, fileName, destinationBucketName, destinationObjectName);
} catch (OSSException oe) {
logger.error("errorCode:{},Message:{},requestID:{}", oe.getErrorCode(), oe.getMessage(), oe.getRequestId());
if (oe.getErrorCode().equals(NO_SUCH_KEY)) {
throw new BusinessException(BusinessErrorCode.NO_SUCH_KEY);
} else if (oe.getErrorCode().equals(NO_SUCH_BUCKET)) {
throw new BusinessException(BusinessErrorCode.NO_SUCH_BUCKET);
} else {
throw new BusinessException(BusinessErrorCode.FAIL);
}
} finally {
shutdown(ossClient);
}
}
private void shutdown(OSSClient ossClient) {
ossClient.shutdown();
}
}
文件类型枚举
package com.example.file.config;
public enum FileTypeEnum {
IMG(1, "图片"),
AUDIO(2, "音频"),
VIDEO(3, "视频"),
APP(4, "App包"),
OTHER(5, "其他");
private Integer code;
private String message;
FileTypeEnum(Integer code, String message) {
this.code = code;
this.message = message;
}
public Integer getCode() {
return code;
}
public String getMessage() {
return message;
}
}
调用工具类上传文件
@Override public ListuploadImg(MultipartFile[] files) { if (files == null) { throw new BusinessException(BusinessErrorCode.OPT_UPLOAD_FILE); } try { return aliyunOSSUtil.uploadFile(files, FileTypeEnum.IMG, aliyunOSSProperties.getBucketProduct(), null, aliyunOSSProperties.getDomainProduct()); } catch (Exception e) { logger.error("uploadImg error e:{}", e); throw new BusinessException(BusinessErrorCode.UPLOAD_FAIL); } }
返回的List是文件上传之后文件的文件名集合。
到此就整合完成了。可以登录OSS控制台查看对应的文件。更多相关SpringBoot整合阿里云OSS内容请搜索考高分网以前的文章或继续浏览下面的相关文章希望大家以后多多支持考高分网！
