Java 当FTP路径有多个子目录时上载空白文件
下面的代码将文件上传到FTP服务器上Java 当FTP路径有多个子目录时上载空白文件,java,file-upload,ftp,ftp-client,Java,File Upload,Ftp,Ftp Client,下面的代码将文件上传到FTP服务器上 public class UploadFile { static ResourceBundle rsBundle = ResourceBundle.getBundle("com.mindcraft.resources.resources"); public void upload(String host,String username,String pwd,String inputfile,String uploadpath,String z
public class UploadFile {
static ResourceBundle rsBundle = ResourceBundle.getBundle("com.mindcraft.resources.resources");
public void upload(String host,String username,String pwd,String inputfile,String uploadpath,String zip_filename)
{
//String zip_file_name= rsBundle.getString("zip_filename");
FTPClient ftp=new FTPClient();
try {
int reply;
ftp.connect(host);
ftp.login(username, pwd);
reply = ftp.getReplyCode();
System.out.println("reply1" + reply);
if(!FTPReply.isPositiveCompletion(reply))
{
ftp.disconnect();
}
System.out.println("FTP server connected.");
ftp.setFileType(FTP.BINARY_FILE_TYPE);
InputStream input= new FileInputStream(inputfile);
System.out.println("Directory.." + ftp.printWorkingDirectory());
String dirTree=uploadpath;
boolean dirExists = true;
String[] directories = dirTree.split("/");
for (String dir : directories )
{
if (!dir.isEmpty() )
{
if (dirExists)
{
dirExists = ftp.changeWorkingDirectory(dir);
ftp.storeFile(dirTree+zip_filename,input);
System.out.println("1..");
}
if (!dirExists)
{
System.out.println("dir tree" + ftp.printWorkingDirectory());
if (!ftp.makeDirectory(dir))
{
throw new IOException("Unable to create remote directory '" + dir + "'. error='" + ftp.getReplyString()+"'");
}
if (!ftp.changeWorkingDirectory(dir))
{
throw new IOException("Unable to change into newly created remote directory '" + dir + "'. error='" + ftp.getReplyString()+"'");
}
System.out.println("dir tree" + ftp.printWorkingDirectory());
ftp.storeFile(dirTree+zip_filename,input);
}
}
}
System.out.println( ftp.getReplyString() );
input.close();
ftp.logout();
}
catch(Exception e)
{
System.out.println("err"+ e);
e.printStackTrace();
}
finally
{
if(ftp.isConnected())
{
try
{
ftp.disconnect();
}
catch(Exception ioe)
{
}
}
}
}
}
当上传路径只有一个文件夹时,它可以正常工作,例如/folder1/
但当存在子文件夹或多个目录时,它会上载字节为0的空白文件,例如/folder1/folder2/
有什么问题吗 ftp.storeFile(dirTree+zip\u文件名,输入)
应在创建所有子目录并转到正确目录的之后调用
顺便说一句,本可以帮助引入makeAndGoToDirectory函数。Joop Eggen明白了这一点,我想补充一点,如果您想要检索文件/目录,那么编写以下代码是一个很好的做法:
String[]directories=dirTree.split(File.separator)代码>
而不是
String[]directories=dirTree.split(“/”)代码>
因为这将使你的代码更具可移植性。FTP服务器并不总是需要保持在Unix/Linux上
