The first answer is yes, FastdFS does not support Windows. Second, I suggest you use MinioCopy the code

One, the introduction

Generally, you choose ali Cloud OSS, Qiniuyun, etc. If you are open source, there are a lot of open source distributed file storage systems out there. If you go online and search “Ceph, GlusterFS,Sheepdog,

Lustre, Swift, Cinder, TFS, HDFS, MooseFS FastDFS, MogileFS “so much, do you have any feeling to see after the analysis of these products, or don’t know which to choose????

This is a comparison article for the mainstream open source distributed file storage system:

Comparison of open source distributed storage systems _ to the end of the world -CSDN blog _ Four major open source distributed storage blog.csdn.net​

Two, that exactly choose which?

2.1. When there is no choice, let’s take a look at the star of Github

2.2 minio is recommended

Minio installation and use

3.1. Windows installation is very simple

Download directly from the official website:

min.io/​min.io

F:\Data is the directory where the files are stored

​

3.3 Java calls minio

There is a corresponding demo on the official website, but the version referenced on the official website is older and the corresponding demo is also older. We can go to Github to see the latest demo.

githug examples:

The following code is based on the official Github fine-tuned example
