minio

将minio交给systemd启动：
编写配置文件：vim /etc/systemd/system/minio.service(配置文件必须位于/etc/systemd/system/ 或 /usr/lib/systemd/system)
[Unit]

minio的管理页面端口 9001
minio的资源端口 9000

基本使用：
public void test01() throws ServerException, InsufficientDataException, ErrorResponseException, IOException, NoSuchAlgorithmException, InvalidKeyException, InvalidResponseException, XmlParserException, InternalException {
String username=”minioadmin”; //账号
String password=”minioadmin”; //密码
String point=”http:192.168.6.100:9000”; //连接的minio服务器地址
String tong=”lease”; //存储到哪个桶
MinioClient minioClient=MinioClient.builder().credentials(username,password).endpoint(point).build(); //构建连接对象(minio全部采用构建器模式)，指定连接地址和账号密码
boolean flag = minioClient.bucketExists(BucketExistsArgs.builder().bucket(tong).build()); //检查桶是否存在，指定桶名称
if(!flag){
minioClient.makeBucket(MakeBucketArgs.builder().bucket(tong).build()); //创建桶，指定桶名称
String policy= “””
{
“Statement” : [ {
“Action” : “s3:GetObject”,
“Effect” : “Allow”,
“Principal” : ““,
“Resource” : “arn:aws:s3:::test/“
} ],
“Version” : “2012-10-17”
} “””; //权限配置
minioClient.setBucketPolicy(SetBucketPolicyArgs.builder().bucket(tong).config(policy).build()); //设置权限，指定设置权限的桶和权限配置
}

    minioClient.uploadObject(UploadObjectArgs.builder()
            .bucket(tong)
            .object("sg.png")
            .filename("C:\\Users\\ASUS\\Pictures\\sg.png")
            .build());  //上传文件，指定上传到哪个桶，上传的文件名称，上传的文件路径
    String url=String.join("/",point,tong,"sg.png");    //上传后资源的访问地址，(拼接的访问路径)
    System.out.println(url);
}

spring.servlet.multipart.max-file-size:100MB 设置单个上传文件大小 Servlet
spring.servlet.multipart.max-request-size:150MB 设置一次请求上传文件大小 Servlet

springdoc.default-flat-param-object:true 将接收参数不做优化处理。(不会把参数误当做json)

BeanUtils.copyProperties(Object source,Object target) 将源对象的同名属性赋值给目标对象
