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：codeup.aliyun.com/6254dee9a92…
1.2、构建镜像
bash
代码解读
复制代码
git clone https://codeup.aliyun.com/6254dee9a923b68581caaf50/kkfileviewer.git
cd kkfileviewer
docker build -t kkfileview:v4.4.0 .
1.3、 启动kkfileviewer
arduino
代码解读
复制代码
docker run -d -p 8012:8012 --name kkfileview kkfileview:v4.4.0
1.4、 访问测试
2、springboot集成minio
2.1 pom.xml添加依赖
xml
代码解读
复制代码
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>8.5.11</version>
</dependency>
2.2、 配置
yaml
代码解读
复制代码
# minio 文件存储配置信息
minio:
endpoint: http://xxxxx:9000
accessKey: xxxx
secretKey: xxxxx
bucketName: test
2.3、minio配置类
kotlin
代码解读
复制代码
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();
}
}
2.4、 minio工具类
java
代码解读
复制代码
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());
}
}
}
2.5、接口
kotlin
代码解读
复制代码
package com.sunny.controller;
import com.sunny.entity.common.ApiResult;
import com.sunny.exception.AppException;
import com.sunny.utils.MinioUtils;
import jakarta.annotation.Resource;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
@RestController
@RequestMapping("/file")
public class FileOperationController {
@Resource
private MinioUtils minioUtils;
@PostMapping("/upload")
public ApiResult upload(MultipartFile file) throws AppException {
return minioUtils.uploadFile(file);
}
@GetMapping("/getPreviewUrl")
public ApiResult getPreviewUrl(String fileName) throws AppException {
return minioUtils.getPreviewUrl(fileName);
}
}
3、测试
3.1、上传文件
3.2、获取minio文件预览地址
3.1中返回一个文件名，该文件名为上传文件在minio中的唯一名称，使用该名称请求minio文件预览地址 
3.3、文件预览
3.2中的接口返回一个地址，将地址放到kkfileviewer文件预览服务中，可以预览文件
