docker快速部署minio文件服务器，springboot整合minio

1. docker部署命令： docker run -d \-p 19000:9000 \-p 9001:9001 \--name minio \-v /home/minio/data:/data \-e "MINIO_ROOT_USER=admin" \-e "MINIO_ROOT_PASSWORD=12345678" \minio/minio server /data --console-address ":9001"

注意：

        服务器19000端口映射minio9000，因为9000端口经常被服务器其他服务占用

        web consoler 地址为 IP:9001

        api访问地址为：IP:19000

2、springboot连接准备

  2.1 登陆后创建bunket

2.2 创建service account 

3、springboot整合

        3.1  pom文件加入依赖。                           

 
     io.minio
     minio
     7.1.0
 

        3.2 在application-dev.yml文件中配置minio

minio:
  endpoint: http://serverip:19000
  accessKey: fsp-manage
  secretKey: springboot-fsp-manage
  bucketName: fsp-dev
 
spring:
     mvc:
      hiddenmethod:
        filter:
          enabled: true
#        设置文件上传大小限制
  servlet:
    multipart:
      max-file-size: 100MB
      max-request-size: 150MB

        3.3   文件存储表创建

CREATE TABLE `minio_file` (
  `id` bigint(20) NOT NULL COMMENT '文件id',
  `project_id` bigint(32) DEFAULT NULL COMMENT '项目ID',
  `res_id` bigint(32) DEFAULT NULL COMMENT '资源ID',
  `original_file_name` varchar(255) DEFAULT NULL COMMENT '原始文件名称',
  `file_ext_name` varchar(15) 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) DEFAULT NULL COMMENT '存入minio时的文件名称',
  `mime` varchar(50) DEFAULT NULL COMMENT '文件的content-type',
  `file_url` varchar(255) DEFAULT NULL COMMENT '文件路径',
  `create_user` varchar(50) DEFAULT NULL COMMENT '创建人',
  `create_time` datetime DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `update_user` varchar(50) DEFAULT NULL COMMENT '修改人',
  `update_time` datetime DEFAULT NULL COMMENT '修改时间',
  `delete_model` int(1) DEFAULT '1' COMMENT '删除标识 1正常数据 0删除数据',
  PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='资产信息表';

        3.4编码
