1、下载相应的jar包
commons-net-3.6.jar
2、具体代码如下
package org.ftp.conntion;
import java.io.File;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTree;
import javax.swing.tree.DefaultMutableTreeNode;
import javax.swing.tree.DefaultTreeModel;
import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPFile;
public class ConnectionFtp extends JFrame{
/**
*
*/
private static final long serialVersionUID = 1L;
static JTree tree;
static DefaultTreeModel newModel;
static DefaultMutableTreeNode Node;
static DefaultMutableTreeNode temp;
public ConnectionFtp() throws IOException {
// TODO Auto-generated constructor stub
FTPClient ftp = ConnFTP("192.168.1.31", "ao", "tech", 21);
Node = ListFTPFile(ftp, ftp.printWorkingDirectory());
ftp.disconnect();
newModel = new DefaultTreeModel(Node);
tree=new JTree(newModel);
this.setSize(400,500);
this.add(new JScrollPane(tree));
this.setResizable(false);
this.setLocationRelativeTo(null);
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.setVisible(true);
}
/*
* FTP链接
* **/
public FTPClient ConnFTP(String host,String user,String pass,int port) throws IOException{
FTPClient ftp=new FTPClient();
ftp.setControlEncoding("GBK");
ftp.connect(host, port);
ftp.login(user, pass);
return ftp;
}
/*
* 关闭ftp链接
* */
public void disConnect(FTPClient ftp){
try {
ftp.logout();
if (ftp.isConnected()) {
ftp.disconnect();
}
} catch (IOException e) {
// TODO: handle exception
e.printStackTrace();
System.exit(1);
}
}
public DefaultMutableTreeNode ListFTPFile(FTPClient ftpClient,String path) throws IOException{
String gbkname;
InputStream iStream = null;
DefaultMutableTreeNode fujiedian = new DefaultMutableTreeNode(path);
System.out.println("当前节点名字:" + fujiedian);
try {
FTPFile[] files = ftpClient.listFiles(); //获取当前路径中的文件并存放到files数组中
System.out.println(ftpClient.printWorkingDirectory() + ":"+files.length);
for (FTPFile file2:files) {
if (file2.isDirectory()) {
String tempDir=ftpClient.printWorkingDirectory()+"/"+file2.getName();
System.out.println("tempdir:" + tempDir);
ftpClient.setFileType(ftpClient.BINARY_FILE_TYPE);
gbkname=file2.getName();
ftpClient.storeFile(new String(gbkname.getBytes("GBK"),"iso-8859-1"), iStream);
System.out.println(ftpClient.printWorkingDirectory());
ftpClient.changeWorkingDirectory(tempDir);
ListFTPFile(ftpClient, tempDir);
fujiedian.add(ListFTPFile(ftpClient, file2.getName()));
ftpClient.changeToParentDirectory();
}
else{
System.out.println(ftpClient.printWorkingDirectory() + "/" + file2.getName());
temp = new DefaultMutableTreeNode(file2.getName());
fujiedian.add(temp);
}
}
} catch (IOException e) {
// TODO: handle exception
e.printStackTrace();
System.exit(1);
}
return fujiedian;
}
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
new ConnectionFtp();
}
}
运行程序后结果如下
