[英]How to send file from linux server to windows server using Java?
我在使用 Java 將文件從 Linux 服務器發送到 windows 服務器時遇到問題。 我使用 jsch 庫來發送文件。 當我從 linux 服務器對 windows 服務器的 990 端口進行遠程登錄時，一切正常。 這是它的外觀：
我寫了這段代碼來發送文件：
protected boolean sendFileToRemoteServer() {
String fileName = redExpressConfigurationProperties.getUploadPath() + "test.txt";
JSch jsch = new JSch();
Session jschSession = null;
boolean returnedValue = false;
try {
jschSession = getSessionOfRemoteServer(jsch);
log.debug("Got Session!");
ChannelSftp channelSftp = getSftpChannelFromSession(jschSession);
channelSftp.put(fileName, redExpressConfigurationProperties.getRemoteServerFilePath());
channelSftp.exit();
log.debug("File sent!");
returnedValue = true;
} catch (JSchException | SftpException e) {
log.error("Exception: ", e);
} finally {
if (jschSession != null) {
jschSession.disconnect();
}
}
return returnedValue;
}
protected Session getSessionOfRemoteServer(JSch jsch) throws JSchException {
Properties properties = new Properties();
properties.put("StrictHostKeyChecking", "no");
Session session = jsch.getSession(redExpressConfigurationProperties.getRemoteServerUser(),
redExpressConfigurationProperties.getRemoteServerAddress(),
redExpressConfigurationProperties.getRemoteServerSshPort()); // port is 990
session.setConfig(properties);
session.setPassword(redExpressConfigurationProperties.getRemoteServerPassword());
log.debug("password: {}", redExpressConfigurationProperties.getRemoteServerPassword());
log.debug("server address: {}", redExpressConfigurationProperties.getRemoteServerAddress());
return session;
}
protected ChannelSftp getSftpChannelFromSession(Session jschSession) throws JSchException {
jschSession.connect(redExpressConfigurationProperties.getRemoteSessionTimeout()); // timeout is 10000
log.debug("Server Connected!");
Channel channel = jschSession.openChannel("sftp");
channel.connect(redExpressConfigurationProperties.getRemoteChannelTimeout());
log.debug("Got sftp channel for session!");
return (ChannelSftp) channel;
}
我的 gradle 依賴是這樣的：
implementation 'com.jcraft:jsch:0.1.55'
這是我的 application.properties 文件的一部分：
但是當我運行代碼時，我在嘗試連接 windows 服務器時遇到異常。 這是日志：

這是我遇到異常的行：
jschSession.connect(redExpressConfigurationProperties.getRemoteSessionTimeout());
我做錯了什么？ 我是否選擇了錯誤的圖書館來達到我的目的？ 是否有任何身份驗證問題？或任何其他問題？
我沒有通過谷歌搜索找到太多幫助。 所以貼在這里。 能得到幫助會很棒。 提前致謝。
