【Java编程系列】Minio实现文件上传下载

1、前言

最近有一客户&＃xff0c;需要独立部署文件存储到自己的私有化服务器&＃xff0c;于是选择了让我们使用在AWS服务器的s3存储桶方式来实现。现做一下实践后的开发经验记录~~~

2、Amazon S3实战代码

2.1 S3的Sdk对接实现

2.1.1 S3 Maven依赖

这里需要说明一下&＃xff0c;目前封装好的java可用的sdk有两种实现依赖&＃xff0c;第一种&＃xff1a;

com.amazonaws aws-java-sdk-s3 1.12.276

以上是第一种封装依赖&＃xff0c;但是这里面会有部分依赖缺失&＃xff0c;在文末的总结中&＃xff0c;可以看到完整的依赖方式。

第二种封装依赖&＃xff1a;

software.amazon.awssdk s3 2.17.100 software.amazon.awssdk kms 2.17.100 software.amazon.awssdk s3control 2.17.100

本来是使用第一种依赖来做的开发编码。后来因为一个403权限拒绝原因&＃xff0c;一开始不确定是否是api问题&＃xff0c;所以后来又使用了s3官方文档推荐的第二种依赖完成了开发实现&＃xff0c;因此以下示例代码&＃xff0c;全都是引用第二种maven依赖来完成的&＃xff01;&＃xff01;&＃xff01;

2.1.2 s3 client配置与初始化

在开始实践编码前&＃xff0c;先列一下本次开发中&＃xff0c;我参考的一些api文档&＃xff0c;希望能给有需要的朋友一些参考和帮助。

S3官方开发指南文档&＃xff1a;使用 AWS SDK for Java 的 Amazon S3示例 - AWS SDK for Java

开发示例代码github地址&＃xff1a;aws-doc-sdk-examples/javav2/example_code/s3/src/main/java/com/example/s3 at main · awsdocs/aws-doc-sdk-examples · GitHub

还有第一种依赖的实现参考代码&＃xff1a;如何使用AWS SDK for Java操作MinIO Server | Minio中文文档

s3存储桶的配置信息&＃xff0c;我这边是使用数据表存储配置的&＃xff0c;因为我们系统的多元化接入。可能会有多套配置&＃xff0c;所以请按需配置。

初始化代码如下&＃xff0c;PrivateUploadConfig类是我的s3配置信息实体类&＃xff1a;

WaiterResponse waiterResponse &＃61; s3Waiter.waitUntilBucketExists(bucketRequestWait); waiterResponse.matched().response().ifPresent(r->log.info(r.toString()));

2.1.3 上传文件

import lombok.extern.slf4j.Slf4j; import org.springframework.stereotype.Component; import org.springframework.web.multipart.MultipartFile; import software.amazon.awssdk.auth.credentials.AwsBasicCredentials; import software.amazon.awssdk.auth.credentials.AwsCredentials; import software.amazon.awssdk.auth.credentials.AwsCredentialsProvider; import software.amazon.awssdk.auth.credentials.AwsCredentialsProviderChain; import software.amazon.awssdk.core.sync.RequestBody; import software.amazon.awssdk.core.waiters.WaiterResponse; import software.amazon.awssdk.regions.Region; import software.amazon.awssdk.services.s3.S3Client; import software.amazon.awssdk.services.s3.model.CreateBucketRequest; import software.amazon.awssdk.services.s3.model.GetObjectRequest; import software.amazon.awssdk.services.s3.model.HeadBucketRequest; import software.amazon.awssdk.services.s3.model.HeadBucketResponse; import software.amazon.awssdk.services.s3.model.PutObjectRequest; import software.amazon.awssdk.services.s3.presigner.S3Presigner; import software.amazon.awssdk.services.s3.presigner.model.GetObjectPresignRequest; import software.amazon.awssdk.services.s3.presigner.model.PresignedGetObjectRequest; import software.amazon.awssdk.services.s3.waiters.S3Waiter; import javax.annotation.Resource; import java.io.ByteArrayInputStream; import java.io.IOException; import java.io.InputStream; import java.time.Duration; import java.util.Objects; /** * &＃64;Date: 2022/8/19 19:40 * &＃64;Description */ &＃64;Component &＃64;Slf4j public class S3ClientUtil private S3Client s3Client; // private S3AsyncClient s3AsyncClient; &＃64;Resource(name &＃61; CommonBeanNames.STRING_REDIS_HELPER) private RedisHelper redisHelper; public void uploadFile(PrivateUploadConfig uploadConfig, String fileName, MultipartFile multipartFile, String contentType) throws IOException if (null &＃61;&＃61; s3Client) init(uploadConfig); PutObjectRequest.Builder putOb &＃61; PutObjectRequest.builder(); putOb.bucket(uploadConfig.getBucket()); putOb.key(fileName); if (StringUtils.isNotEmpty(contentType)) putOb.contentType(contentType); long begin &＃61; System.currentTimeMillis(); s3Client.putObject(putOb.build(), RequestBody.fromInputStream(multipartFile.getInputStream(), multipartFile.getInputStream().available())); log.info("S3 putObject time :", System.currentTimeMillis() - begin);

2.1.4 下载文件

2.1.5 生成文件预签名url

import lombok.extern.slf4j.Slf4j; import org.springframework.stereotype.Component; import org.springframework.web.multipart.MultipartFile; import software.amazon.awssdk.auth.credentials.AwsBasicCredentials; import software.amazon.awssdk.auth.credentials.AwsCredentials; import software.amazon.awssdk.auth.credentials.AwsCredentialsProvider; import software.amazon.awssdk.auth.credentials.AwsCredentialsProviderChain; import software.amazon.awssdk.core.sync.RequestBody; import software.amazon.awssdk.regions.Region; import software.amazon.awssdk.services.s3.S3Client; import software.amazon.awssdk.services.s3.model.GetObjectRequest; import software.amazon.awssdk.services.s3.model.PutObjectRequest; import software.amazon.awssdk.services.s3.presigner.S3Presigner; import software.amazon.awssdk.services.s3.presigner.model.GetObjectPresignRequest; import software.amazon.awssdk.services.s3.presigner.model.PresignedGetObjectRequest; import javax.annotation.Resource; import java.io.ByteArrayInputStream; import java.io.IOException; import java.io.InputStream; import java.time.Duration; import java.util.Objects; /** * &＃64;Date: 2022/8/19 19:40 * &＃64;Description */ &＃64;Component &＃64;Slf4j public class S3ClientUtil private S3Client s3Client; // private S3AsyncClient s3AsyncClient; &＃64;Resource(name &＃61; CommonBeanNames.STRING_REDIS_HELPER) private RedisHelper redisHelper; public String getObjectURL(PrivateUploadConfig uploadConfig, String fileName) if (fileName.indexOf("/") &＃61;&＃61; 0) fileName &＃61; fileName.replaceFirst("/", ""); S3Presigner presigner &＃61; S3Presigner.builder() .credentialsProvider(getProvider(uploadConfig)) .region(Region.of(uploadConfig.getRegion())) .build(); GetObjectRequest getObjectRequest &＃61; GetObjectRequest.builder() .bucket(uploadConfig.getBucket()) .key(fileName) .build(); //默认生成的预览url最大时效时间为&＃xff1a;7天&＃xff0c;aws s3能允许的最大时限也是7天 GetObjectPresignRequest getObjectPresignRequest &＃61; GetObjectPresignRequest.builder() .signatureDuration(Duration.ofDays(7)) .getObjectRequest(getObjectRequest) .build(); PresignedGetObjectRequest presignedGetObjectRequest &＃61; presigner.presignGetObject(getObjectPresignRequest); String theUrl &＃61; presignedGetObjectRequest.url().toString(); log.info("Origin path : , Presigned URL: ", fileName, theUrl); return theUrl;

2.1.6 文件“永久性”访问实现

其实S3存储桶&＃xff0c;通过策略配置&＃xff0c;是可以直接通过域名&＃43;桶名称&＃43;文件路径名称 &＃xff0c;来直接永久访问到的。但是&＃xff0c;这么做的话&＃xff0c;安全性就大大降低了。所以&＃xff0c;我们需要采取其他的方式来间接实现永久访问的功能。于是&＃xff0c;有了一下曲线救国的方针&＃xff1a;

通过定时任务&＃xff0c;根据你生成预签名url的最大时效来&＃xff0c;往后推一点时间&＃xff0c;来生成需要更新的时间周期。

例如&＃xff0c;我选择最大时效为7天&＃xff0c;那么我会定时任务&＃xff0c;每天查询图片url时效已达过6天的记录&＃xff0c;然后重新生成新的url更新到记录里&＃xff0c;如此&＃xff0c;就可以间接性的永久有效啦~~~

2.1.7 其他操作&＃xff08;解决下载慢&＃xff09;

还有很多其他api&＃xff0c;如删除文件、获取存储桶列表、获取文件列表&＃xff1b;另外还有一些&＃xff0c;针对不同region或是高版本api&＃xff0c;还有transfer等高效高性能方法可用。

另外&＃xff0c;使用第一种依赖&＃xff0c;还能实现一些分段上传、下载。官方建议&＃xff0c;当单个文件大小超过100M时&＃xff0c;则需要使用分段上传下载处理。

但是&＃xff0c;我这里遇到了一个其他问题&＃xff1a;上传和下载很慢的问题 &＃xff0c;这个问题我分析主要是来自于网络传输效率低所导致&＃xff0c;不在代码层面。测试用例&＃xff1a;一个10M左右的文件&＃xff0c;上传需要10&＃43;秒&＃xff0c;下载更是达到60秒左右。

得出以上结论的原因有&＃xff1a;

1、同样的s3实现&＃xff0c;我们其他使用aws服务器的朋友&＃xff0c;他们使用上传下载时&＃xff0c;就没有这个慢的情况出现&＃xff0c;至少不会像我这个情况。

2、我使用本地文件&＃xff0c;对代码进行测试&＃xff0c;除了s3的api调用处&＃xff0c;其他代码运行效率都很高&＃xff0c;只在毫秒级别&＃xff0c;使用的是同一个大小的原文件测试的。

3、使用断点调试时&＃xff0c;发现s3Client.putObject(&＃xff09;方法&＃xff0c;阻塞所占时间为主要耗时&＃xff1b;另外&＃xff0c;对于s3Client.getObject(&＃xff09;下载方法&＃xff0c;虽然程序调用在毫秒级&＃xff0c;但最终将文件流输出时&＃xff0c;底层实际是通过s3服务端的url实时传输的&＃xff0c;所以也是传出效率低所导致&＃xff01;

最终&＃xff0c;我先想了一个方式&＃xff0c;解决下载慢的问题。因为一个文件下载要1min多&＃xff0c;实在是太不能接受了。上传10s左右&＃xff0c;还得过且过吧。

对于下载慢的问题&＃xff0c;我使用的方式时&＃xff0c;在上传完成后&＃xff0c;使用redis缓存文件流来解决&＃xff01;

String fis &＃61; new String(multipartFile.getBytes(),"ISO8859-1"); redisHelper.hset(cacheKey,fileId,fis);

以上是缓存实现的关键代码。对于为什么字符串编码选择使用 ISO8859-1 &＃xff0c;因为也有与base64转码做过性能对比&＃xff0c;发现前者的性能更优。大家可以参考使用&＃xff01;

3、总结

整体实践完成后&＃xff0c;有一些开发过程中遇到的问题&＃xff0c;在这里总结一下。帮助大家避坑~~~
