实现 文件上传【头像/图片】
实现 文件上传【头像/图片】浏览器---->后端服务----->阿里云OSS
工具类
@Data
@AllArgsConstructor
@Slf4j
public class AliOssUtil {
private String endpoint;
private String accessKeyId;
private String accessKeySecret;
private String bucketName;
/**
* 文件上传
*
* @param bytes
* @param objectName
* @return
*/
public String upload(byte[] bytes, String objectName) {
// 创建OSSClient实例。
OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
try {
// 创建PutObject请求。
ossClient.putObject(bucketName, objectName, new ByteArrayInputStream(bytes));
} catch (OSSException oe) {
System.out.println("Caught an OSSException, which means your request made it to OSS, "
+ "but was rejected with an error response for some reason.");
System.out.println("Error Message:" + oe.getErrorMessage());
System.out.println("Error Code:" + oe.getErrorCode());
System.out.println("Request ID:" + oe.getRequestId());
System.out.println("Host ID:" + oe.getHostId());
} catch (ClientException ce) {
System.out.println("Caught an ClientException, which means the client encountered "
+ "a serious internal problem while trying to communicate with OSS, "
+ "such as not being able to access the network.");
System.out.println("Error Message:" + ce.getMessage());
} finally {
if (ossClient != null) {
ossClient.shutdown();
}
}
//文件访问路径规则 https://BucketName.Endpoint/ObjectName
StringBuilder stringBuilder = new StringBuilder("https://");
stringBuilder
.append(bucketName)
.append(".")
.append(endpoint)
.append("/")
.append(objectName);
log.info("文件上传到:{}", stringBuilder.toString());
return stringBuilder.toString();
}
}代码实现
[*]在application.yml中编写相关信息
sky:
alioss:
endpoint: oss-cn-hangzhou.aliyuncs.com
access-key-id: LTAI5tJKk5H21ZmQQ9CgeG8y
access-key-secret: 90xHhXxKqg6LNnbb4ubp1BeIdw7RAT
bucket-name: sky-zy2596
[*]编写AliOssProperties ，将yml文件信息映射到AliOssProperties对象中
@Component
@ConfigurationProperties(prefix = "sky.alioss")
@Data
public class AliOssProperties {
private String endpoint;
private String accessKeyId;
private String accessKeySecret;
private String bucketName;
}
[*]编写配置类，创建AliOssUtil对象
/**
* 配置类，用于创建AliOssUtil对象
*/
@Configuration
@Slf4j
public class OssConfiguration {
@Bean
@ConditionalOnMissingBean//保证spring容器只有一个AliOssUtil对象
public AliOssUtil aliOssUtil(AliOssProperties aliOssProperties ){//将aliOssProperties 中的属性赋给AliOssUtil对象
log.info("开始创建阿里云文件上传工具类对象：{}",aliOssProperties);
return new AliOssUtil(aliOssProperties.getEndpoint()
,aliOssProperties.getAccessKeyId()
,aliOssProperties.getAccessKeySecret()
,aliOssProperties.getBucketName());
}
}
[*]编写文件上传接口
@PostMapping("/upload")
@ApiOperation("文件上传")
public Result<String> upload(MultipartFile file){// file 这里的参数名必须和前端提交的参数名保持一致
log.info("文件上传:{}",file);
try {
//原始文件名
String originalFilename = file.getOriginalFilename();
//截取原始文件名的后缀
String extension = originalFilename.substring(originalFilename.lastIndexOf("."));
//构造新文件名称
String objectName = UUID.randomUUID().toString() + extension;
//文件的请求路径
String filePath = aliOssUtil.upload(file.getBytes(), objectName);
return Result.success(filePath);
} catch (IOException e) {
log.error("文件上传失败：{}",e);
}
return Result.error("文件上传失败");
}
