手把手教你SpringBoot轻松整合Minio

前言

使用Spring Boot 可以非常方便、快速搭建项目,使我们不用关心框架之间的兼容性,适用版本等各种问题,我们想使用任何东西,仅仅添加一个配置就可以。

提示：以下是本篇文章正文内容，下面案例可供参考

一、技术介绍
1.Minio是什么？

MinIO 是一个基于Apache License v2.0开源协议的对象存储服务。它兼容亚马逊S3云存储服务接口，非常适合于存储大容量非结构化的数据，例如图片、视频、日志文件、备份数据和容器/虚拟机镜像等，而一个对象文件可以是任意大小，从几kb到最大5T不等。

二、使用步骤
1.引入maven库

代码如下（示例）：

	 	
	    org.springframework.boot
	    spring-boot-starter-parent
	    2.4.1
	    
	  
    
    
      io.minio
      minio
      8.0.3

2.封装Minio

IFile类：

package com.hyh.minio;


public interface IFile {

  
  void upload(String filename);

  
  void upload(String filename, String object);
}

File接口类：

package com.hyh.minio.service;

import com.hyh.minio.IFile;


public interface FileService extends IFile {

  
  void upload(String filename, String object, String bucket);
}

File接口实现类：

package com.hyh.minio.service.impl;

import com.hyh.minio.service.FileService;
import com.hyh.utils.common.StringUtils;
import io.minio.BucketExistsArgs;
import io.minio.MakeBucketArgs;
import io.minio.MinioClient;
import io.minio.UploadObjectArgs;
import io.minio.errors.MinioException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;

import java.io.IOException;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;


@Service
public class FileServiceImpl implements FileService {

  
  private static final Logger LOG = LoggerFactory.getLogger(FileServiceImpl.class);

  
  @Autowired
  private MinioClient minioClient;

  
  @Value("${minio.bucketName:}")
  private String defaultBucketName;


  @Override
  public void upload(String filename) {
    uploadObject(filename, null, defaultBucketName);
  }

  @Override
  public void upload(String filename, String object) {
    uploadObject(filename, object, defaultBucketName);
  }


  @Override
  public void upload(String filename, String object, String bucket) {
    uploadObject(filename, object, bucket);
  }

  
  private void uploadObject(String filename, String object, String bucket) {
    if (StringUtils.isAnyBlank(filename, bucket))
      return;
    try {
      //存储桶构建
      bucketBuild(bucket);
      //保存的文件名称
      object = StringUtils.isBlank(object) ? filename.substring(filename.lastIndexOf("/") > 0 ? filename.lastIndexOf("/") : filename.lastIndexOf("\")) : object;

      minioClient.uploadObject(
   UploadObjectArgs.builder()
.bucket(bucket)
.object(object)
.filename(filename)
.build());
    } catch (MinioException | InvalidKeyException | IOException | NoSuchAlgorithmException exception) {
      LOG.error("uploadObject error", exception);
    }
  }


  
  private void bucketBuild(String bucketName) {
    try {
      boolean found =
   minioClient.bucketExists(BucketExistsArgs.builder().bucket(bucketName).build());
      if (!found) {
 minioClient.makeBucket(MakeBucketArgs.builder().bucket(bucketName).build());
 LOG.info("Bucket " + bucketName + " make success.");
      } else {
 LOG.info("Bucket " + bucketName + " already exists.");
      }
    } catch (MinioException | InvalidKeyException | IOException | NoSuchAlgorithmException exception) {
      LOG.error("bucketBuild error", exception);
    }
  }

  public String getDefaultBucketName() {
    return defaultBucketName;
  }

  public void setDefaultBucketName(String defaultBucketName) {
    this.defaultBucketName = defaultBucketName;
  }
}

Minio配置类：

package com.hyh.minio.config;

import io.minio.MinioClient;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
@ConfigurationProperties(prefix = "minio")
public class MinioConfig {

  
  private String endpoint;

  
  private int port;

  
  private String accessKey;

  
  private String secretKey;

  
  private Boolean secure;

  
  private String bucketName;

  
  private String configDir;

  @Bean
  public MinioClient getMinClient() {
    return MinioClient.builder()
 .endpoint(endpoint, port, secure)//http
 .credentials(accessKey, secretKey)
 .build();
  }


  public String getEndpoint() {
    return endpoint;
  }

  public void setEndpoint(String endpoint) {
    this.endpoint = endpoint;
  }

  public String getAccessKey() {
    return accessKey;
  }

  public void setAccessKey(String accessKey) {
    this.accessKey = accessKey;
  }

  public String getSecretKey() {
    return secretKey;
  }

  public void setSecretKey(String secretKey) {
    this.secretKey = secretKey;
  }

  public Boolean getSecure() {
    return secure;
  }

  public void setSecure(Boolean secure) {
    this.secure = secure;
  }

  public String getBucketName() {
    return bucketName;
  }

  public void setBucketName(String bucketName) {
    this.bucketName = bucketName;
  }

  public String getConfigDir() {
    return configDir;
  }

  public void setConfigDir(String configDir) {
    this.configDir = configDir;
  }

  public int getPort() {
    return port;
  }

  public void setPort(int port) {
    this.port = port;
  }
}

Minio助手类封装：

package com.hyh.minio.helper;

import com.hyh.minio.service.FileService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.util.Assert;


@Component
public class MinioHelper {

  
  private static final Logger LOG = LoggerFactory.getLogger(MinioHelper.class);

  
  @Autowired
  private FileService fileService;


  
  public void upload(String filename) {
    Assert.notNull(filename, "filename is null.");
    fileService.upload(filename);
  }

  
  public void upload(String filename, String object) {
    Assert.notNull(filename, "filename is null.");
    Assert.notNull(object, "object is null.");
    fileService.upload(filename, object);
  }

  
  public void upload(String filename, String object, String bucket) {
    Assert.notNull(filename, "filename is null.");
    Assert.notNull(object, "object is null.");
    Assert.notNull(bucket, "bucket is null.");
    fileService.upload(filename, object, bucket);
  }


}

3.配置文件

代码如下（示例）：

server:
 port: 8088
#minio配置
minio:
 endpoint: 39.108.49.252
 port: 9000
 accessKey: admin
 secretKey: admin123
 secure: false
 bucketName: "hyh-bucket"
 configDir: "/home/data/"

4.单元测试

测试代码如下（示例）：

package com.hyh.core.test;

import com.hyh.core.test.base.HyhTest;
import com.hyh.minio.helper.MinioHelper;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;


public class MinioTest extends HyhTest {

  @Autowired
  private MinioHelper minioHelper;

  @Test
  public void testUpload() {
    //直接指向你本地的路径测试
    String filename = "E:\home\static\img\fsPic\0c34de99ac6b4c56812e83c4eab13a6f.jpg";
    String object = "hyh-test-name.jpg";
    String bucket = "hyh-test-bucket";
    minioHelper.upload(filename);
    minioHelper.upload(filename, object);
    minioHelper.upload(filename, object, bucket);
    //上传完后打开浏览器访问 http://ip:9000 登录控制台可查看上传的文件
  }

  @Test
  @Override
  public void test() {
    System.out.println("---minio 测试---");
  }
}
