SpringBoot + minio + kkfile 实现文件预览

东湖之滨 · 2024-12-17 21:20:23

1、容器安装kkfileviewer

1.1 下载文件

这里以kkfile 4.4.0-beta版本为例
下载kkfile安装包及Dockerfile：
https://codeup.aliyun.com/6254dee9a923b68581caaf50/kkfileviewer.git
1.2、构建镜像

git clone https://codeup.aliyun.com/6254dee9a923b68581caaf50/kkfileviewer.git
cd kkfileviewer
docker build -t kkfileview:v4.4.0 .

复制代码

1.3、启动kkfileviewer

docker run -d -p 8012:8012 --name kkfileview kkfileview:v4.4.0

复制代码

1.4、访问测试

http://you-ip:8012

2、springboot集成minio

2.1 pom.xml添加依靠

<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>8.5.11</version>
</dependency>

复制代码

2.2、设置

# minio 文件存储配置信息
minio:
endpoint: http://xxxxx:9000
accessKey: xxxx
secretKey: xxxxx
bucketName: test

复制代码

2.3、minio设置类

package com.sunny.config;
import io.minio.MinioClient;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MinioConfig {
@Value("${minio.endpoint}")
private String endPoint;
@Value("${minio.accessKey}")
private String accessKey;
@Value("${minio.secretKey}")
private String secretKey;
@Value("${minio.bucketName}")
private String bucketName;
@Bean
protected MinioClient minioClient(){
return MinioClient.builder()
.endpoint(endPoint)
.credentials(accessKey, secretKey)
.build();
}
}

复制代码

2.4、 minio工具类

package com.sunny.utils;
import com.sunny.entity.common.ApiResult;
import com.sunny.exception.AppException;
import io.minio.GetPresignedObjectUrlArgs;
import io.minio.MinioClient;
import io.minio.PutObjectArgs;
import io.minio.http.Method;
import jakarta.annotation.Resource;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import org.springframework.web.multipart.MultipartFile;
import java.io.InputStream;
@Component
public class MinioUtils {
@Value("${minio.bucketName}")
private String bucketName;
@Resource
private MinioClient minioClient;
public ApiResult uploadFile(MultipartFile file) throws AppException {
String fileName = System.currentTimeMillis() + file.getOriginalFilename();
try (InputStream fi = file.getInputStream()) {
PutObjectArgs putObjectArgs = PutObjectArgs.builder().bucket(bucketName).contentType(file.getContentType()).object(fileName).stream(fi, fi.available(), -1).build();
minioClient.putObject(putObjectArgs);
} catch (Exception e) {
throw new AppException("文件上传失败" + e.getMessage());
}
return ApiResult.ok(fileName);
}
public ApiResult getPreviewUrl(String objectName) throws AppException {
try {
GetPresignedObjectUrlArgs urlArgs = GetPresignedObjectUrlArgs.builder().bucket(bucketName).object(objectName).method(Method.GET).build();
return ApiResult.ok(minioClient.getPresignedObjectUrl(urlArgs));
} catch (Exception e) {
throw new AppException("获取预览链接失败" + e.getMessage());
}
}
}
