创建minio-demo,对应pom如下

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <artifactId>heima-leadnews-test</artifactId>
        <groupId>com.heima</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>minio-demo</artifactId>

    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
    </properties>

    <dependencies>

        <dependency>
            <groupId>io.minio</groupId>
            <artifactId>minio</artifactId>
            <version>7.1.0</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>

            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
    </dependencies>

</project>

引导类：

package com.heima.minio;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;


@SpringBootApplication
public class MinIOApplication {

    public static void main(String[] args) {
        SpringApplication.run(MinIOApplication.class,args);
    }
}

创建测试类，上传html文件

package com.heima.minio.test;

import io.minio.MinioClient;
import io.minio.PutObjectArgs;

import java.io.FileInputStream;

public class MinIOTest {


    public static void main(String[] args) {

        FileInputStream fileInputStream = null;
        try {

            fileInputStream =  new FileInputStream("D:\\list.html");;

            //1.创建minio链接客户端
            MinioClient minioClient = MinioClient.builder().credentials("minio", "minio123").endpoint("http://192.168.200.130:9000").build();
            //2.上传
            PutObjectArgs putObjectArgs = PutObjectArgs.builder()
                    .object("list.html")//文件名
                    .contentType("text/html")//文件类型
                    .bucket("leadnews")//桶名词  与minio创建的名词一致
                    .stream(fileInputStream, fileInputStream.available(), -1) //文件流
                    .build();
            minioClient.putObject(putObjectArgs);

            System.out.println("http://192.168.200.130:9000/leadnews/ak47.jpg");

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

封装MinIO为starter

1 创建模块heima-file-starter

导入依赖

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-autoconfigure</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>
    <dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
</dependencies>

2 配置类

MinIOConfigProperties

package com.heima.file.config;


import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;

import java.io.Serializable;

@Data
@ConfigurationProperties(prefix = "minio")  // 文件上传 配置前缀file.oss
public class MinIOConfigProperties implements Serializable {

    private String accessKey;
    private String secretKey;
    private String bucket;
    private String endpoint;
    private String readPath;
}

MinIOConfig

package com.heima.file.config;

import com.heima.file.service.FileStorageService;
import io.minio.MinioClient;
import lombok.Data;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Data
@Configuration
@EnableConfigurationProperties({MinIOConfigProperties.class})
//当引入FileStorageService接口时
@ConditionalOnClass(FileStorageService.class)
public class MinIOConfig {

   @Autowired
   private MinIOConfigProperties minIOConfigProperties;

    @Bean
    public MinioClient buildMinioClient(){
        return MinioClient
                .builder()
                .credentials(minIOConfigProperties.getAccessKey(), minIOConfigProperties.getSecretKey())
                .endpoint(minIOConfigProperties.getEndpoint())
                .build();
    }
}

3 封装操作minIO类

FileStorageService

package com.heima.file.service;

import java.io.InputStream;

/**
 * @author itheima
 */
public interface FileStorageService {


    /**
     *  上传图片文件
     * @param prefix  文件前缀
     * @param filename  文件名
     * @param inputStream 文件流
     * @return  文件全路径
     */
    public String uploadImgFile(String prefix, String filename,InputStream inputStream);

    /**
     *  上传html文件
     * @param prefix  文件前缀
     * @param filename   文件名
     * @param inputStream  文件流
     * @return  文件全路径
     */
    public String uploadHtmlFile(String prefix, String filename,InputStream inputStream);

    /**
     * 删除文件
     * @param pathUrl  文件全路径
     */
    public void delete(String pathUrl);

    /**
     * 下载文件
     * @param pathUrl  文件全路径
     * @return
     *
     */
    public byte[]  downLoadFile(String pathUrl);

}

        }catch (Exception ex){
            log.error("minio put file error.",ex);
            throw new RuntimeException("上传文件失败");
        }
    }

        }
    }

    /**

     */
    @Override
    public void delete(String pathUrl) {
        String key = pathUrl.replace(minIOConfigProperties.getEndpoint()+"/","");
        int index = key.indexOf(separator);
        String bucket = key.substring(0,index);
        String filePath = key.substring(index+1);
        // 删除Objects
        RemoveObjectArgs removeObjectArgs = RemoveObjectArgs.builder().bucket(bucket).object(filePath).build();
        try {
            minioClient.removeObject(removeObjectArgs);
        } catch (Exception e) {
            log.error("minio remove file error.  pathUrl:{}",pathUrl);
            e.printStackTrace();
        }
    }


    /**

     *
     */

        String key = pathUrl.replace(minIOConfigProperties.getEndpoint()+"/","");
        int index = key.indexOf(separator);

            }
            byteArrayOutputStream.write(buff, 0, rc);
        }
        return byteArrayOutputStream.toByteArray();
    }
}

4 对外加入自动配置

在resources中新建META-INF/spring.factories

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
  com.heima.file.service.impl.MinIOFileStorageService

5 其他微服务使用

第一，导入heima-file-starter的依赖

第二，在微服务中添加minio所需要的配置

minio:
  accessKey: minio
  secretKey: minio123
  bucket: leadnews
  endpoint: http://192.168.200.130:9000
  readPath: http://192.168.200.130:9000

第三，在对应使用的业务类中注入FileStorageService，样例如下：

package com.heima.minio.test;


import com.heima.file.service.FileStorageService;
import com.heima.minio.MinioApplication;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.io.FileInputStream;
import java.io.FileNotFoundException;

@SpringBootTest(classes = MinioApplication.class)
@RunWith(SpringRunner.class)
public class MinioTest {

    @Autowired
    private FileStorageService fileStorageService;

    @Test
    public void testUpdateImgFile() {
        try {
            FileInputStream fileInputStream = new FileInputStream("E:\\tmp\\ak47.jpg");
            String filePath = fileStorageService.uploadImgFile("", "ak47.jpg", fileInputStream);
            System.out.println(filePath);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}
