搭建高性能分布式存储-minio

Docker搭建minio（单机部署+纠删码模式）⭐

• 1：使用minio Docker镜像，在在单机中使用EC纠删码模式部署，8块盘中启动minio服务：
  • 注意：MINIO_ROOT_PASSWORD初始化默认密码长度必须要达到8位。

docker run --name minio -d \-p 9000:9000 \-p 50000:50000 \-v /mnt/minio/data1:/data1 \-v /mnt/minio/data2:/data2 \-v /mnt/minio/data3:/data3 \-v /mnt/minio/data4:/data4 \-v /mnt/minio/data5:/data5 \-v /mnt/minio/data6:/data6 \-v /mnt/minio/data7:/data7 \-v /mnt/minio/data8:/data8\-e MINIO_ROOT_USER="root" \-e MINIO_ROOT_PASSWORD="12345678" \minio/minio:latest server /data{1...8} --console-address ":50000"

• 2：访问minio控制台：（http://服务器ip:50000/）

创建minio的bucket（桶）⭐

SpringBoot+minio项目实战 ⭐

1：导入minio的maven依赖

<dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>8.4.3</version>
</dependency><dependency><groupId>commons-io</groupId><artifactId>commons-io</artifactId><version>2.6</version>
</dependency>

2：编写MinioProperties.class

package com.boot.config;import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.stereotype.Component;/*** 高性能分布式存储-minio属性类** @author youzhengjie* @date 2022/10/28 00:22:48*/
@Component
@Data
@ConfigurationProperties(prefix = "minio")
@EnableConfigurationProperties({MinioProperties.class
})
public class MinioProperties {/*** minio的通信端点（url），和控制台端点不一样*/private String endpoint;/*** 说白了就是minio的帐号*/private String accessKey;/*** 说白了就是minio的密码*/private String secretKey;/*** 指定操作哪一个桶*/private String bucketName;
}

3：application.yml：

• 注意：记得把下面的配置属性修改成你自己的！

minio:endpoint: http://192.168.184.123:9000access-key: rootsecret-key: 12345678bucket-name: security-jwt2-bucket

4：MinioConfig.class配置类

• 作用是将MinioClient交给Spring管理，方便后续直接@AutoWired注入即可使用）

package com.boot.config;import io.minio.MinioClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** minio配置类** @author youzhengjie* @date 2022/10/28 00:30:31*/
@Configuration
public class MinioConfig {@Autowiredprivate MinioProperties minioProperties;/*** minio-client bean** @return {@link MinioClient}*/@Beanpublic MinioClient minioClient(){return MinioClient.builder()//配置minio的通信端点（url），和控制台端点不一样.endpoint(minioProperties.getEndpoint())//配置minio的帐号密码.credentials(minioProperties.getAccessKey(), minioProperties.getSecretKey()).build();}}

5：ResponseResult（统一响应结果）

package com.boot.data;import com.fasterxml.jackson.annotation.JsonInclude;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;/*** 统一响应结果*/
@JsonInclude(JsonInclude.Include.NON_NULL) //为null的字段不进行序列化
@Data
@NoArgsConstructor
@AllArgsConstructor
public class ResponseResult<T> {/*** 响应状态码*/private Integer code;/*** 响应状态码对应的信息提示*/private String msg;/*** 返回给前端的数据*/private T data;public ResponseResult(Integer code, String msg) {this.code = code;this.msg = msg;}public ResponseResult(Integer code, T data) {this.code = code;this.data = data;}}

6:ResponseType（响应类型枚举类）

package com.boot.enums;/*** 响应类型枚举类* @author youzhengjie* @date 2022-09-22 22:47:21*/
public enum ResponseType {/*** 文件操作状态*/IMAGE_UPLOAD_SUCCESS(901,"图片上传成功"),IMAGE_UPLOAD_ERROR(902,"图片上传失败"),FILE_FORMAT_UNSUPPORT(903,"不支持该文件格式，上传失败"),FILE_DELETE_SUCCESS(904,"文件删除成功"),FILE_DELETE_ERROR(905,"文件删除失败"),;private int code;private String message;ResponseType(int code, String message) {this.code = code;this.message = message;}public int getCode() {return code;}public void setCode(int code) {this.code = code;}public String getMessage() {return message;}public void setMessage(String message) {this.message = message;}
}

7：UploadController.class（上传接口）

@RestController
@Api("上传接口")
@RequestMapping(path = "/upload")
@Slf4j
public class UploadController {@Autowired@Qualifier("minioUploadServiceImpl") //指定spring注入的实现类private OssUploadService ossUploadService;/*** 上传头像** @param avatarFile 头像文件（名字一定要和el-upload的:name属性一致）* @return {@link ResponseResult}*/@OperationLog("上传头像")@PostMapping(path = "/avatar")@ApiOperation("上传头像")public ResponseResult uploadAvatar(MultipartFile avatarFile){ResponseResult result = ossUploadService.imageUpload(avatarFile);return result;}/*** 文件删除** @param fileFullName 文件名* @return {@link ResponseResult}*/@OperationLog("文件删除")@DeleteMapping(path = "/fileDelete")@ApiOperation("文件删除")public ResponseResult fileDelete(@RequestParam("fileFullName") String fileFullName){return ossUploadService.fileDelete(fileFullName);}/*** 文件下载** @param fileName 文件名称* @param response 响应*/@GetMapping(path = "/fileDownload")@ApiOperation("文件下载")public void fileDownload(@RequestParam("fileName") String fileName, HttpServletResponse response){ossUploadService.fileDownload(fileName,response);}
}

8：上传service接口

package com.boot.service;import com.boot.data.ResponseResult;
import org.springframework.web.multipart.MultipartFile;
import javax.servlet.http.HttpServletResponse;/*** oss上传service接口* @author youzhengjie* @date 2022-10-06 23:13:28*/
public interface OssUploadService {/*** oss图片上传* @param imageFile* @return 上传结果*/ResponseResult imageUpload(MultipartFile imageFile);/*** oss文件删除* @param fileFullName 文件全名，** @return 删除结果*/ResponseResult fileDelete(String fileFullName);/*** 文件下载** @param fileName 文件名称* @param response 响应*/default void fileDownload(String fileName, HttpServletResponse response){throw new UnsupportedOperationException("该实现类暂不支持文件下载操作,请切换到其他实现类！");}}

9：上传service接口实现类：

package com.boot.service.impl;import com.boot.config.MinioProperties;
import com.boot.data.ResponseResult;
import com.boot.enums.ResponseType;
import com.boot.service.OssUploadService;
