Spring Boot 整合 Minio
Demo 地址：mingyue-springboot-minio
1.添加依赖
<!-- minio 依赖 -->
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>8.3.9</version>
</dependency>
<!-- minio 依赖于 okhttp -->
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>4.9.0</version>
</dependency>
2.修改配置文件
minio:
endpoint: http://IP:9000
port: 9000
accessKey: 登录账号
secretKey: 登录密码
secure: false
bucket-name: mingyue-test # 桶名
image-size: 10485760 # 图片文件的最大大小
file-size: 1073741824 # 文件的最大大小
3.创建 Minio 配置类
import io.minio.MinioClient;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;
/**
* Minio 配置
*
* @author Strive
* @date 2022/4/25 10:20
* @description
*/
@Data
@Component
@ConfigurationProperties(prefix = "minio")
public class MinioPropertiesConfig {
/** 服务地址 */
private String endpoint;
/** TCP/IP端口号 */
private Integer port;
/** 账户 */
private String accessKey;
/** 密码 */
private String secretKey;
/** 如果是 true，则用的是 https 而不是 http,默认值是 true" */
private boolean secure;
/** 存储桶 */
private String bucketName;
/** 图片的最大大小 */
private long imageSize;
/** 其他文件的最大大小 */
private long fileSize;
/** 初始化 MinIO 客户端 */
@Bean
public MinioClient minioClient() {
return MinioClient.builder().endpoint(endpoint).credentials(accessKey, secretKey).build();
}
}
4.创建 Minio 工具类

5.创建 Minio Service
import cn.hutool.core.util.IdUtil;
import cn.hutool.core.util.StrUtil;
import com.csp.mingyue.minio.config.MinioPropertiesConfig;
import com.csp.mingyue.minio.util.MinioUtil;
import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;
/**
* Minio 服务层
*
* @author Strive
* @date 2022/4/25 10:32
* @description Minio Service 层
*/
@Slf4j
@Service
@RequiredArgsConstructor
public class MinioService {
private final MinioPropertiesConfig minioPropertiesConfig;
private final MinioUtil minioUtil;
/**
* 检查存储桶是否存在
*
* @param bucketName 存储桶名称
*/
public boolean bucketExists(String bucketName) {
return minioUtil.bucketExists(bucketName);
}
/**
* 创建存储桶
*
* @param bucketName 存储桶名称
*/
public void makeBucket(String bucketName) {
minioUtil.makeBucket(bucketName);
}
/**
* 文件上传
*
* @param file 上传的文件
* @param bucketName 桶名称
* @param fileType 文件类型
*/
public String upload(MultipartFile file, String bucketName, String fileType) {
if (StrUtil.isBlank(bucketName)) {
log.info("bucketName is null");
}
try {
if (!this.bucketExists(bucketName)) {
this.makeBucket(bucketName);
}
String fileName = file.getOriginalFilename();
assert fileName != null;
String objectName =
IdUtil.randomUUID().replace("-", "") + fileName.substring(fileName.lastIndexOf("."));
minioUtil.putObject(bucketName, file, objectName, fileType);
return minioPropertiesConfig.getEndpoint() + "/" + bucketName + "/" + objectName;
} catch (Exception e) {
e.printStackTrace();
return "上传失败";
}
}
/**
* 获取文件路径
*
* @param bucketName 桶名称
* @param objectName 对象名称
*/
public String getObjectUrl(String bucketName, String objectName) {
return minioUtil.getObjectUrl(bucketName, objectName);
}
}
6.Minio 接口
import com.csp.mingyue.minio.config.MinioPropertiesConfig;
import com.csp.mingyue.minio.service.MinioService;
import lombok.RequiredArgsConstructor;
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.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
/**
* Minio 接口
*
* @author Strive
* @date 2022/4/25 10:48
* @description
*/
@RestController
@RequestMapping("/minio")
@RequiredArgsConstructor
public class MinioController {
private final MinioPropertiesConfig minioPropertiesConfig;
private final MinioService minioService;
@PostMapping("/upload")
public String upload(@RequestParam(name = "multipartFile") MultipartFile multipartFile) {
return minioService.upload(
multipartFile, minioPropertiesConfig.getBucketName(), multipartFile.getContentType());
}
@GetMapping("/getObjectUrl")
public String getObjectUrl(String objectName) {
return minioService.getObjectUrl(minioPropertiesConfig.getBucketName(), objectName);
}
}
7.测试接口
-
Post http://127.0.0.1:8080/minio/upload 上传接口
接口返回如下：
http://ip:port/mingyue-test/60396cc92fec4e2cbb4a974d810e7115.jpg -
Get http://127.0.0.1:8080/minio/getObjectUrl?objectName=60396cc92fec4e2cbb4a974d810e7115.jpg 查询接口
接口返回如下：
http://ip:port/mingyue-test/60396cc92fec4e2cbb4a974d810e7115.jpg?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=admin%2F20220425%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20220425T055235Z&X-Amz-Expires=120&X-Amz-SignedHeaders=host&X-Amz-Signature=35eeffddca22f8211a1af0e936066e848a988e82b73548cfc87f2294e0861f01
补充说明
只写了两个接口，想要查询桶列表或者其他功能具体看
MinioUtil函数，主要可以参考如下文档：
