Springboot整合minio实现文件服务的教程详解
作者：洛阳泰山
这篇文章主要介绍了Springboot整合minio实现文件服务的教程，文中的示例代码讲解详细，对我们的工作或学习有一定帮助，需要的可以参考一下
首先pom文件引入相关依赖
<!--minio-->
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>3.0.10</version>
</dependency>springboot配置文件application.yml 里配置minio信息
#minio配置
minio:
endpoint: http://${minio_host:172.16.10.21}:9000/
accessKey: ${minio_user:minioadmin}
secretKey: ${minio_pwd:minioadmin}
bucket: ${minio_space:spacedata}
http-url: http://${minio_url:172.16.10.21}:9000/
imgSize: 10485760
fileSize: 1048576000创建MinioItem字段项目类

try {

}catch(NullPointerException e){}
}
public String convertFileSize(long size) {
long kb = 1024;
long mb = kb * 1024;
long gb = mb * 1024;
if (size >= gb) {
