哪位大侠有 “根据图片本地路径地址上传图片到Linux服务器”的JAVA代码呀？

您好，提问者：

1、这个我建议使用FTP传输，如果不是自动传输的可以使用FTP方便。

2、写程序的话要建立Socket客户端、和 ServerSocket服务端才可以实现。

可以用ftp实现文件的上传下载，跟linux还是windows没有关系。

把linux作为remote server就可以了。

public static void backupUploadWithCommonsFTP(File fileToBeUpload) {

FTPClient f = new FTPClient();

boolean backupDirectoryExist = false;

boolean fileToBeUploadExist = false;

FTPFile backupDirectory = null;

try {

fconnect(servergetServer());

flogin(servergetUsername(), servergetPassword());

FTPFile[] directories = flistDirectories();

// Check for existence of backup directory

for (FTPFile file : directories) {

String filename = filegetName();

if (fileisDirectory() && filenameequalsIgnoreCase("backup")) {

backupDirectory = file;

backupDirectoryExist = true;

break;

}

}

if (!backupDirectoryExist) {

fmakeDirectory("backup");

}

// Check if file already exist on the server

fchangeWorkingDirectory("files");

FTPFile[] files = flistFiles();

fchangeWorkingDirectory("backup");

String filePathToBeBackup="/home/user/backup/";

String prefix;

String suffix;

String fileNameToBeBackup;

FTPFile fileReadyForBackup = null;

fsetFileType(FTPBINARY_FILE_TYPE);

fsetFileTransferMode(FTPBINARY_FILE_TYPE);

for (FTPFile file : files) {

if (fileisFile() && filegetName()equals(fileToBeUploadgetName())) {

prefix = FilenameUtilsgetBaseName(filegetName());

suffix = ""concat(FilenameUtilsgetExtension(filegetName()));

fileNameToBeBackup = prefixconcat(CalendargetInstance()getTime()toString()concat(suffix));

filePathToBeBackup = filePathToBeBackupconcat(fileNameToBeBackup);

fileReadyForBackup = file;

fileToBeUploadExist = true;

break;

}

}

// If file already exist on the server create a backup from it otherwise just upload the file

if(fileToBeUploadExist){

ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

fretrieveFile(fileReadyForBackupgetName(), outputStream);

InputStream is = new ByteArrayInputStream(outputStreamtoByteArray());

if(fstoreUniqueFile(filePathToBeBackup, is)){

JOptionPaneshowMessageDialog(null, "Backup succeeded");

fchangeWorkingDirectory("files");

boolean reply = fstoreFile(fileToBeUploadgetName(), new FileInputStream(fileToBeUpload));

if(reply){

JOptionPaneshowMessageDialog(null,"Upload succeeded");

}else{

JOptionPaneshowMessageDialog(null,"Upload failed after backup");

}

}else{

JOptionPaneshowMessageDialog(null,"Backup failed");

}

}else{

fchangeWorkingDirectory("files");

fsetFileType(FTPBINARY_FILE_TYPE);

fenterLocalPassiveMode();

InputStream inputStream = new FileInputStream(fileToBeUpload);

ByteArrayInputStream in = new ByteArrayInputStream(FileUtilsreadFileToByteArray(fileToBeUpload));

boolean reply = fstoreFile(fileToBeUploadgetName(), in);

Systemoutprintln("Reply code for storing file to server: " + reply);

if(!fcompletePendingCommand()) {

flogout();

fdisconnect();

Systemerrprintln("File transfer failed");

Systemexit(1);

}

if(reply){

JOptionPaneshowMessageDialog(null,"File uploaded successfully without making backup" +

"\nReason: There wasn't any previous version of this file");

}else{

JOptionPaneshowMessageDialog(null,"Upload failed");

}

}

//Logout and disconnect from server

inclose();

flogout();

fdisconnect();

} catch (IOException e) {

eprintStackTrace();

}

}

你是想从服务器下载文件吧？那应该用retrieveFile(String remote, OutputStream local)，而不是storefile啊，自己看看API
