• 引言

在开发过程中，偶尔会遇到网络文件在FTP服务上存储着，对于这种情况想要下载到本地还有些麻烦，我们直接上世界上最简单的代码。

• How to do

1.提前引入包

        <!--hutool万能工具包--><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.4.4</version></dependency><!-- 网络编程 --><dependency><groupId>commons-net</groupId><artifactId>commons-net</artifactId><version>3.6</version></dependency>

2.逻辑代码实现

    public static void main(String[] args) throws Exception{String dir = "/";String fileName = "xxx.flv";Ftp ftp = new Ftp("192.168.1.99",21);ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();ftp.download(dir, fileName, byteArrayOutputStream);byte[] bytes = byteArrayOutputStream.toByteArray();FileOutputStream fileOutputStream = new FileOutputStream("C:/Users/Administrator/Desktop/"+fileName);fileOutputStream.write(bytes);}
