写一段java代码，可以将本地文件上传到linux服务器

以下是一个简单的Java代码示例，可以将本地文件上传到Linux服务器上：

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;

public class FileUploader {
    
    public static void main(String[] args) {
        String localFilePath = "/path/to/local/file";
        String remoteFilePath = "/path/to/remote/file";
        String remoteHost = "remote_host";
        String remoteUser = "remote_user";
        String remotePassword = "remote_password";
        int remotePort = 22;
        
        try {
            uploadFile(localFilePath, remoteFilePath, remoteHost, remoteUser, remotePassword, remotePort);
            System.out.println("File uploaded successfully!");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
    public static void uploadFile(String localFilePath, String remoteFilePath, String remoteHost, String remoteUser, String remotePassword, int remotePort) throws Exception {
        JSch jsch = new JSch();
        Session session = jsch.getSession(remoteUser, remoteHost, remotePort);
        session.setPassword(remotePassword);

        Properties config = new Properties();
        config.put("StrictHostKeyChecking", "no");
        session.setConfig(config);

        session.connect();

        Channel channel = session.openChannel("sftp");
        channel.connect();
        ChannelSftp sftpChannel = (ChannelSftp) channel;

        File localFile = new File(localFilePath);
        InputStream inputStream = new FileInputStream(localFile);
        sftpChannel.put(inputStream, remoteFilePath);

        sftpChannel.exit();
        session.disconnect();
    }

}

需要使用到JSch库，可以在Maven中添加以下依赖：

<dependency>
    <groupId>com.jcraft</groupId>
    <artifactId>jsch</artifactId>
    <version>0.1.55</version>
</dependency>

其中，`localFilePath`表示本地文件的路径，`remoteFilePath`表示远程服务器上保存文件的路径，`remoteHost`表示远程服务器的IP地址，`remoteUser`和`remotePassword`表示登录远程服务器的用户名和密码，`remotePort`表示远程服务器的SSH端口号。
