springboot中如何使用minio存储容器

docker运行

docker run
  -p 9000:9000   
  -p 9001:9001   
  -v /mydata/minio/data:/data  
  minio/minio server /data --console-address ":9001

java导包

最好是这个版本，其他版本尝试过都出bug了

		<dependency>
            <groupid>io.minio</groupid>
            <artifactid>minio</artifactid>
            <version>8.2.1</version>
        </dependency>

配置文件

spring:
  # 上传文件大小设置
  servlet:
    multipart:
      enabled: true
      max-file-size: 50mb
minio:
  endpoint: xxx:9000
  accesskey: xxx
  secretkey: xxx
  bucketname: xxx

操作

1、编写一个属性文件

@data
@component
@configurationproperties(prefix = "minio") // 从配置文件的前缀拿
public class minioproperties {

    private string endpoint;
    private string accesskey;
    private string secretkey;
}

2、编写一个minioclient

@configuration
public class minioconfig {

    @resource
    private minioproperties minioproperties;

    @bean
    public minioclient minioclient() {
        system.out.println(minioproperties.getaccesskey());
        system.out.println(minioproperties.getsecretkey());
        minioclient minioclient = minioclient.builder()
                .endpoint(minioproperties.getendpoint())
                .credentials(minioproperties.getaccesskey(), minioproperties.getsecretkey())
                .build();
        return minioclient;
    }
}

3、上传文件api

public class minioserviceimpl implements minioservice {

    @value("${minio.bucketname}")
    private string bucketname;
    @value("${minio.endpoint}")
    private string endpoint;

    @resource
    private minioclient minioclient;

    @override
    public list<string> uploadfile(multipartfile[] file) throws serverexception, insufficientdataexception, errorresponseexception, nosuchalgorithmexception, invalidkeyexception, invalidresponseexception, xmlparserexception, internalexception {
        if (file == null || file.length == 0) {
            throw new apiexception(resultcode.param_is_blank);
        }
        list<string> fileurllist = new arraylist<>(file.length);
        string url = "";
        for (multipartfile multipartfile : file) {
            // 1.获取文件名
            string originalfilename = multipartfile.getoriginalfilename();
            // 2.截取后缀名
            string imgsuffix = originalfilename.substring(originalfilename.lastindexof("."));
            // 3.生成唯一名
            string newfilename = uuid.randomuuid().tostring() + imgsuffix;
            // 4.日期目录
            simpledateformat dateformat = new simpledateformat("yyyy/mm/dd");
            string datapath = dateformat.format(new date());
            // 5.合成路径
            string finalfilename = datapath + "/" + newfilename;
            // 别忘了bucketname
            url = endpoint + "/" + bucketname + "/" + finalfilename;
            try {
                // 文件上传
                inputstream in = multipartfile.getinputstream();
                minioclient.putobject(putobjectargs.builder().bucket(bucketname).object(finalfilename).stream(
                        in, multipartfile.getsize(), -1)
                        .contenttype(multipartfile.getcontenttype())
                        .build());
                in.close();
                fileurllist.add(url);
            } catch (ioexception e) {
                throw new apiexception(resultcode.common_fail);
            }
        }
        return fileurllist;
    }
}
