我想在java应用程序中下载一个文件,当我尝试它时,它会在我的硬盘驱动器上创建该文件但无法完全下载它.我正在使用ftp4j库来做到这一点.
import it.sauronsoftware.ftp4j.*;
public class Main {
public static void main (String args[]){
FTPClient client = new FTPClient();
try{
client.connect("ftp.myaddress.comlu.com");
client.login("username", "password");
System.out.println("Connection created");
client.download("public_html/ZScreen.png", new java.io.File("d:/xxx/ZScreen.png"));
System.out.println("Download successful");
client.disconnect(true);
}
catch (Exception FTPException){
System.out.println("Shit hit the fan");
}
}
}
我总是创建Connection并且Shit击中粉丝.此外,我的硬盘驱动器上创建了一个文件,但它的大小为0字节.
这是堆栈竞赛
Connection created
java.net.SocketException: Connection reset
Shit hit the fan
