**这篇文章主要介绍了手把手教你SpringBoot轻松整合Minio的方法，帮助大家更好的理解和使用springboot框架，感兴趣的朋友可以了解下**

**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）：**

<parent>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-parent</artifactId>
          <version>2.4.1</version>
          <relativePath/>
        </parent>
      <dependencies>
      <dependency>
        <groupId>io.minio</groupId>
        <artifactId>minio</artifactId>
        <version>8.0.3</version>
      </dependency>
    </dependencies>

**2.封装Minio**  
**IFile类：**

package com.hyh.minio;
     
    /**
     * File接口类
     *
     * @Author: heyuhua
     * @Date: 2021/1/12 10:33
     */
    public interface IFile {
        
     
      /**
       * 上传
       *
       * @param filename 文件名
       */
      void upload(String filename);
     
      /**
       * 上传
       *
       * @param filename 文件名
       * @param object  保存对象文件名称
       */
      void upload(String filename, String object);
    }

**File接口类：**

package com.hyh.minio.service;
     
    import com.hyh.minio.IFile;
     
    /**
     * File接口
     *
     * @Author: heyuhua
     * @Date: 2021/1/12 10:53
     */
    public interface FileService extends IFile {
        
     
      /**
       * 上传
       *
       * @param filename 文件名称
       * @param object  保存对象文件名称
       * @param bucket  存储桶
       */
      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 java.security.NoSuchAlgorithmException;
     
    /**

    @Service

      /**

       */
      private static final Logger LOG = LoggerFactory.getLogger(FileServiceImpl.class);
     
      /**
       * minio 客户端
       */
      @Autowired
      private MinioClient minioClient;
     
      /**
       * 默认存储桶名称
       */
      @Value("${minio.bucketName:}")
      private String defaultBucketName;
     
     
      @Override

      }

      }

       * @param bucket
       */
      private void uploadObject(String filename, String object, String 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()

        } catch (MinioException | InvalidKeyException | IOException | NoSuchAlgorithmException exception) {
        
          LOG.error("uploadObject error", exception);
        }
      }
     
     
      /**
       * 存储桶构建
       *
       * @param bucketName
       */
      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 void setDefaultBucketName(String defaultBucketName) {
        
        this.defaultBucketName = defaultBucketName;
      }
    }

**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;`
    
    `/**`
    
    `* Minio Test`
    
    `*`
    
    `* @Author: heyuhua`
    
    `* @Date: 2021/1/12 11:54`
    
    `*/`
    
    `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](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---"``);`
    
    `}`
    
    `}`
