## windows 下安装Minio ##

**1、下载安装包**  
官网地址 [https://min.io/][https_min.io]

github地址：[https://github.com/minio/minio][https_github.com_minio_minio]

windows 服务端下载地址：[ https://dl.minio.io/server/minio/release/windows-amd64/minio.exe][https_dl.minio.io_server_minio_release_windows-amd64_minio.exe]

**2、安装：**  
打开cmd，切换路径到下载好的minio.exe的文件路径下。

此处我是直接放到E盘下面，然后执行如下命令。

.\minio.exe server E:\minio

后面的E:\\minio 是自己指定的文件目录，用来存放数据

打开上图Endpoint 中的任意一个地址就能访问到页面![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0VzY19UYWJfRW5k_size_16_color_FFFFFF_t_70_pic_center 1]  
使用RootUser和RootPass登录进入。

**3、创建和上传文件**

到此，安装的部分就完成了。

## 下面来介绍springboot集成Minio ##

**1、首先我们先引入minio的maven配置：**

<dependency>
            <groupId>io.minio</groupId>
            <artifactId>minio</artifactId>
            <version>7.1.0</version>
        </dependency>

**2、在配置文件中配置minio的服务地址**

#minIO 地址
    minio:
      endpoint: http://192.168.1.203
      port: 9000
      accessKey: minioadmin
      secretKey: minioadmin
      bucketName: iletter

**3、创建配置类**

import io.minio.MinioClient;
    import io.minio.errors.InvalidEndpointException;
    import io.minio.errors.InvalidPortException;
    import org.springframework.boot.context.properties.ConfigurationProperties;
    import org.springframework.context.annotation.Bean;
    import org.springframework.stereotype.Component;
    
    @Component
    @ConfigurationProperties(prefix = "minio")
    public class MinioConfig{ 
        private String endpoint;
        private int port;
        private String accessKey;
        private String secretKey;
        private Boolean secure;
        private String bucketName;
        
        @Bean
        public MinioClient getMinioClient() throws InvalidEndpointException, InvalidPortException { 
            MinioClient minioClient = MinioClient.builder().endpoint(endpoint, port, secure)
                            .credentials(accessKey, secretKey)
                            .build();
            return minioClient;
        }
    }

**4、创建API实现代码**

import io.minio.*;
    import io.minio.errors.*;
    import io.minio.http.Method;
    import io.minio.messages.Bucket;
    import io.minio.messages.DeleteError;

                //这里就用service类来做写入库表操作，这里的Map是为了便于阅读，正常情况下，是要传入业务数据的，只是在此处蒋图片的路径保存到images字段中。
                indexService.addfeedback(map);
                modelMap.put("code","1");

**6、效果展示**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0VzY19UYWJfRW5k_size_16_color_FFFFFF_t_70_pic_center 3]  
上传的图片，就上传到了iletter桶下 feelback对象中，该对象的路径是如图，包含了用户id，序号，时间错，大小。这是我个人的命名规则。

**7、权限问题：**  
MinIo中图片可以分享，但是分享时间不超过7天，如果想要图片链接永久可以访问，那么要设置该路径的所有文件都有读权限。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0VzY19UYWJfRW5k_size_16_color_FFFFFF_t_70_pic_center 4]

设置了feeldback/ 前缀开头的所有路径都有读取权限后，就可以通过图片的路径链接直接访问图片了。  
访问链接格式：ip:port/bucketName/objectName 不包含minio这一段。  
例如下图：

到此，简单入门的springboot集成MinIO就完成了，后续的正删改查的接口，就不用一一演示了。
