首先配置ftp.properties
ftpip=10.192.88.60
ftpuser=eftp
ftppassword=eftp
#localpath=/home/eftp
编写读ftp.properties文件类；
public class ReadFtpProperties{
private InputStream is;
private Properties properties;
public ReadFtpProperties() {
is = this.getClass().getResourceAsStream("ftp.properties");
properties = new Properties();
try {
properties.load(is);
} catch (IOException e) {
System.out.println("配置文件不存在..");
e.printStackTrace();
} finally {
if (null != is) {
try { is.close();
} catch (IOException e) {
System.out.println("关闭流失败.."); e.printStackTrace();
}
}
}
}
public String getIp() {
// 获取ftp服务器的ip地址 return properties.getProperty("ftpIp"); }
public String getUser() {
// 获取ftp登录用户名 return properties.getProperty("ftpuser");
}
public String getPwd() {
// 获取ftp服务器的登录密码 return properties.getProperty("ftppassword");
}
public String getRemotePath() {
// 获取ftp服务器的存放文件的目录 return properties.getProperty("#localpath"); }
}
ftp文件下载类
public class FtpDownload {
/**
* FTP下载单个文件
*/
public static boolean testDownload(String remoteFile,String localFile) {
FTPClient ftpClient = new FTPClient();
FileOutputStream fos = null;
boolean bool;
boolean bool1;
try {
String ftpIP=IWapContext.getProperty("POSFtp.IP", "127.0.0.1");
String ftpUsername=ReadFtpProperties.getUser();
String ftpPassword=ReadFtpProperties.getPwd();
String remoteFile1=ReadFtpProperties.getRemotePath();
ftpClient.connect(ftpIP);
bool1=ftpClient.login(ftpUsername,ftpPassword);
String remoteFileName = remoteFile1+remoteFile;
fos = new FileOutputStream(localFile);
ftpClient.setBufferSize(1024);
//设置文件类型（二进制）
ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
bool=ftpClient.retrieveFile(remoteFileName, fos);
} catch (IOException e) {
e.printStackTrace();
throw new RuntimeException("FTP客户端出错！", e);
} finally {
IOUtils.closeQuietly(fos);
try {
ftpClient.disconnect();
} catch (IOException e) {
e.printStackTrace();
throw new RuntimeException("关闭FTP连接发生异常！", e);
}
}
return bool&&bool1;
}
}
