ftp操作
1、ftp实体bean
package org.imos.cfdispatch.util.ftp;
public class FTPEntityBean {
String hostName;
String userName;
String password;
String port;
String DownloadPath;
String SaveFilePath;
public FTPEntityBean(String hostName, String userName, String password,
String port, String downloadPath, String saveFilePath) {
super();
this.hostName = hostName;
this.userName = userName;
this.password = password;
this.port = port;
DownloadPath = downloadPath;
SaveFilePath = saveFilePath;
}
public String getDownloadPath() {
return DownloadPath;
}
public void setDownloadPath(String downloadPath) {
DownloadPath = downloadPath;
}
public String getHostName() {
return hostName;
}
public void setHostName(String hostName) {
this.hostName = hostName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getPort() {
return port;
}
public void setPort(String port) {
this.port = port;
}
public String getSaveFilePath() {
return SaveFilePath;
}
public void setSaveFilePath(String saveFilePath) {
SaveFilePath = saveFilePath;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
}
2.ftp连接
package org.imos.cfdispatch.util.ftp;
import java.io.IOException;
import java.net.SocketException;
import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPReply;
public class FtpLogin {
/**
*
* @Title: connectFTP
* @Description:连接FTP服务器
* @param @param ftpbean
* @param @return 设定文件
* @return FTPClient 返回类型
* @throws
*/
public static FTPClient connectFTP(FTPEntityBean ftpbean) {
FTPClient downloadFtp = new FTPClient();
String hostName=ftpbean.getHostName();
String userName=ftpbean.getUserName();
String password=ftpbean.getPassword();
String port=ftpbean.getPort();
int reply;
try {
downloadFtp.setDataTimeout(2000);
downloadFtp.connect(hostName, Integer.parseInt(port));
reply = downloadFtp.getReplyCode();
if (!FTPReply.isPositiveCompletion(reply)) {
downloadFtp.disconnect();
return null;
}
if (!downloadFtp.login(userName, password)) {
downloadFtp.logout();
return null;
}
} catch (SocketException ex) {

}
}
}
return downloadFtp;
}
public void getFTPProper(){
}
}
