springboot集成Minio
1、Minio单击安装
mkdir /data/minio cd /data/minio chmod +x minio mkdir data mkdir logs wget https://dl.min.io/server/minio/release/linux-amd64/minio
2、将Minio的账密写入环境变量中
vim /etc/profile export MINIO_ROOT_USER=username export MINIO_ROOT_PASSWORD=password source /etc/profile
3、启动Minio(9002-server端口，9001-web端口)
nohup ./minio server --address :9002 --console-address :9001 /data/minio/data > /data/minio/logs/minio.log 2>&1 &
4、Springboot依赖
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>7.1.0</version>
</dependency>
5、yml配置
server:
port: 8084
servlet:
context-path: /minio
minio:
endpoint: http://ip:9002
domain: ${minio.endpoint}/${minio.bucketName}
bucketName: zjk-minio
accessKey: root
secretKey: password
secure: false
spring:
servlet:
multipart:
max-file-size: 100MB
max-request-size: 150MB
6、MinioConfig
package com.zjk.config;
import io.minio.MinioClient;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Data
@Configuration
@ConfigurationProperties(prefix = "minio")
public class MinioConfig {
private String endpoint;
private String domain;
private int port;
private String accessKey;
private String secretKey;
private String bucketName;
@Bean
public MinioClient getMinioClient(){
MinioClient minioClient = MinioClient.builder().endpoint(endpoint)
.credentials(accessKey, secretKey)
.build();
return minioClient;
}
}
7、实现类
package com.zjk.service.impl;
import com.zjk.config.MinioConfig;
import com.zjk.service.ISysFileService;
import io.minio.*;
import io.minio.errors.*;
