java代码实现FTP方式上传文件
作者:互联网
1、需要的依赖jar包
<!-- https://mvnrepository.com/artifact/commons-net/commons-net-->
<dependency>
<groupId>commons-net</groupId>
<artifactId>commons-net</artifactId>
<version>3.6</version>
</dependency>
<!-- https://mvnrepository.com/artifact/commons-fileupload/commons-fileupload -->
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.1</version>
</dependency>
2、实现代码
import org.apache.commons.io.IOUtils;
import org.apache.commons.net.ftp.FTPClient;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.Date;

public class test {
public static void main(String[] args){
Upload("xx.xxx.xxx.xx",21,"xxxx","xxxxx","D:\\123.xls","1123.xls");
}
/**
* 需要的参数 依次是 ftp地址 ftp端口 ftp用户名 ftp密码 想要上传的文件路径 上传后文件的名称
* @param url
* @param port

* @param ftpFile
*/
public static void Upload(String url,Integer port,String username,String password,String filePath,String ftpFile) {
FTPClient ftpClient = new FTPClient();
FileInputStream fis = null;
try {
ftpClient.connect(url,port);
ftpClient.login(username, password);
File srcFile = new File(filePath);
fis = new FileInputStream(srcFile);
String fileTimeName = String.valueOf(new Date().getTime());
//设置上传目录
//在根目录下创建003文件夹
ftpClient.makeDirectory("003");
//切换工作空间到003文件夹下
ftpClient.changeWorkingDirectory("003/");
//创建 文件名为 fileTimeName 的文件夹
ftpClient.makeDirectory(fileTimeName);
//切换工空间带该目录下
ftpClient.changeWorkingDirectory(fileTimeName+"/");
//创建 文件名为 FF-FF-FF-FF-FF-FF 的文件夹
ftpClient.makeDirectory("FF-FF-FF-FF-FF-FF");
//切换工空间带该目录下
ftpClient.changeWorkingDirectory("FF-FF-FF-FF-FF-FF/");
ftpClient.setBufferSize(1024);
ftpClient.setControlEncoding("GBK");
//设置文件类型(二进制)
ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE);
ftpClient.enterLocalPassiveMode();
boolean flag = ftpClient.storeFile(new String(ftpFile.getBytes("UTF-8"),"iso-8859-1"),fis);
//如果文件上传成功 则再上传一个 标记文件 [也可以不要]
FileInputStream fis_2 = null;
if(flag){
fis_2=new FileInputStream(new File(filePath));
boolean flag_1 =ftpClient.storeFile(new String((ftpFile+".ok").getBytes("UTF-8"),"iso-8859-1"),fis_2);
}
fis.close();
fis_2.close();
} catch (IOException e) {

throw new RuntimeException("FTP客户端出错!", e);
} finally {
IOUtils.closeQuietly(fis);
try {

} catch (IOException e) {

}
}
}
