Linux安装MinIO及springboot项目整合使用实战(详细)

news/2024/10/30 9:29:27/

以往的项目,用的比较多的OSS服务是腾讯云和阿里云的存储服务,不过从去年到今年,最近的几个项目,普遍要使用Minio,所以我在开发服务器和测试服务器上都装上了minio

一、首先minio的安装

MInIO的安装有很多方法、单实例的、集群分布式的、docker部署的、支持k8s的,我们使用最简单的一种安装方式:linux单节点安装。

如果希望对MinIO有深入的掌握,访问MinIO官网:https://min.io

1.1 安装工作

首先在/root目录下创建一个minio文件夹

cd /root
mkdir minio
cd minio
wget https://dl.min.io/server/minio/release/linux-amd64/minio
![在这里插入图片描述](https://img-blog.csdnimg.cn/b6e3c77f87d948149c7212e9774452a5.png)

等待下载完成后:

在当前minio目录下,会出现一个minio目录

chmod +x minio# 创建minio文件存储目录及日志目录
mkdir -p /root/data/minio;
mkdir -p /root/logs/minio;

然后在 /root/minio/目录下,新建一个run.sh并编辑以下内容

vim run.sh,然后将以下内容保存到run.sh,并为其赋予执行权限chmod u+x run.sh

#!/bin/bash
export MINIO_ROOT_USER=fsp-manage
export MINIO_ROOT_PASSWORD=springboot-fsp-manage
# nohup启动服务 指定文件存放路径 /root/data 还有设置日志文件路径 /root/minio/log
nohup ./minio server --address :9002 --console-address :9001 /root/data/minio > /root/logs/minio/minio.log 2>&1 &

注意:以前的老版本minio的配置中,配置用户名和密码时,是这两个参数:

MINIO_ACCESS_KEY 和MINIO_SECRET_KEY

而现在比较新的版本的minio,需要替换成MINIO_ROOT_USER和MINIO_ROOT_PASSWORD

并且用户名和密码都是由长度限制的,用户名长度不能小于3,密码不能小于8个字符

当然,minio安装完成,以及配置完成后,启动项目的run.sh的时候,如果你设置的用户名和密码长度不够,会有警告提示的,还有就是如果你的配置参数写成以前的旧版本的参数,也会提示你替换成对应的MINIO_ROOT_USER和MINIO_ROOT_PASSWORD

–address :9002 --console-address :9001 是配置端口,默认minio端口是9000,如果9000端口被占用了,那就加上这一串配置,端口号的冒号之前不需要特意写出ip,当然如果你的ip的动态变化的,而不是静态的话,前边的ip不用写上,当然最好是用静态的ip

然后启动minio

# 启动minio服务
bash run.sh
# 查看日志
tail -200f /root/logs/minio/minio.log

然后会有日志打印信息,然后可以看到minio服务器地址,和控制台信息地址

然后在浏览器中访问地址

http://192.168.0.131:9002,输入这个地址后会重定向到控制台登录地址http://192.168.0.131:9001/login

然后在登录界面输入用户名和密码即可登录

然后登录后进入首页,创建一个bucket

创建一个fsp-test,区分开发环境和测试环境,当然我在开发环境服务器上创建的是fsp-dev,由于当前在开发阶段,所以项目中我也配置的是fsp-dev这个桶

接下来我以开发环境中的桶演示minio文件的上传和下载等

二,springboot项目整合MinIO的javaSDK

2.1 项目的pom文件中引入minio依赖

 <properties><maven.compiler.source>8</maven.compiler.source><maven.compiler.target>8</maven.compiler.target><minio.version>7.1.0</minio.version></properties><dependencies><dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>${minio.version}</version></dependency></dependencies>

2.2 在application-dev.yml文件中配置minio

minio:endpoint: http://serveripport: 9002accessKey: fsp-managesecretKey: springboot-fsp-managebucketName: fsp-devsecure: falsespring:mvc:hiddenmethod:filter:enabled: true
#        设置文件上传大小限制servlet:multipart:max-file-size: 100MBmax-request-size: 150MB

2.3 创建minio配置类和工具类

配置类:

package com.xiaomifeng1010.minio.configuration;import io.minio.MinioClient;
import io.minio.errors.InvalidPortException;
import lombok.Getter;
import lombok.Setter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;/*** @author xiaomifeng1010* @version 1.0* @date: 2022/5/20 10:30* @Description minio配置*/
@Configuration
@Component
@ConfigurationProperties(prefix = "minio")
@Getter
@Setter
public class MinioConfig {private String endpoint;private int port;private String accessKey;private String secretKey;private Boolean secure;private String bucketName;@Beanpublic MinioClient getMinioClient() throws InvalidPortException {MinioClient minioClient = MinioClient.builder().endpoint(endpoint, port, secure).credentials(accessKey, secretKey).build();return minioClient;}
//
//    @Bean(name = "multipartResolver")
//    public MultipartResolver multipartResolver(){
//        CommonsMultipartResolver resolver = new CommonsMultipartResolver();
//        resolver.setDefaultEncoding("UTF-8");
//        //resolveLazily属性启用是为了推迟文件解析,以在在UploadAction中捕获文件大小异常
//        resolver.setResolveLazily(true);
//        resolver.setMaxInMemorySize(40960);
//        //上传文件大小 50M 50*1024*1024
//        resolver.setMaxUploadSize(50*1024*1024);
//        return resolver;
//    }
}

如何你要配置ip和port在同一个参数中,不分开,或者是直接配置域名(域名映射了ip和port),那么配置的yml 修改如下:

把port注释掉,同时配置类也修改一下就可以了:

}

2.3 创建一个数据表,用于保存上传到minio的文件的信息

CREATE TABLE `minio_file` (`id` bigint(20) NOT NULL COMMENT '文件id',`original_file_name` varchar(255) COLLATE utf8mb4_bin DEFAULT NULL COMMENT '原始文件名称',`file_ext_name` varchar(15) COLLATE utf8mb4_bin DEFAULT NULL COMMENT '文件拓展名',`file_size` bigint(20) DEFAULT NULL COMMENT '文件大小(单位:字节)',`file_name` varchar(35) COLLATE utf8mb4_bin DEFAULT NULL COMMENT '存入minio时的文件名称',`mime` varchar(50) COLLATE utf8mb4_bin DEFAULT NULL COMMENT '文件的content-type',`file_url` varchar(255) COLLATE utf8mb4_bin DEFAULT NULL COMMENT '文件路径',`is_delete` tinyint(1) DEFAULT NULL COMMENT '是否删除 0 否 1 是',`create_by` varchar(25) COLLATE utf8mb4_bin DEFAULT NULL,`create_time` datetime DEFAULT NULL,`update_by` varchar(25) COLLATE utf8mb4_bin DEFAULT NULL,`update_time` datetime DEFAULT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin;

然后使用idea自动代码生成插件,生成对应的实体类,mapper和service层

2.4 创建minio上传接口

package com.dcboot.module.minio.controller;import cn.hutool.core.io.FileUtil;

为了在上传文件后,把问价地址返回给前端,所以封装了一个返回数据对象DTO

package com.dcboot.module.minio.dto.response;import lombok.Data;/*** @author xiaomifeng1010* @version 1.0* @date: 2022/5/21 14:03* @Description*/
@Data
public class MinioResponseDTO {private  Long fileId;private String fileUrl;private String originalFileName;
}

然后启动项目在knife4j文档页面测试,或者在postman中测试
在这里插入图片描述

由于设置了文件上传的最大限制,所以超出100兆,会抛出异MaxUploadSizeExceededException

,所以需要在全局异常处理器中处理
