连接sftp并实时跟踪上传进度
1.导⼊sftpf的jar包 jsch-0.1.54.jar （jar版本太低会影响测试效果）
2.配置⽂件
host=192.168.132.138
urname=root
password=root
privateKey=/home/webusr/.ssh
passphra=id_rsa
port=22
local=/data/sftp/silver2KF/
movePath=/usr/local/src/test

4.实现接⼝SftpProgressMonitor, Runnable
SftpProgressMonitor：主要⽬的是获取开上传与上传结束
Runnable：实时获取上传进度
NumberFormat;
import urrent.Executors;
import urrent.ScheduledExecutorService;
import urrent.TimeUnit;
import org.apache.log4j.Logger;
import com.jcraft.jsch.SftpProgressMonitor;
public class SftpMonitor implements SftpProgressMonitor, Runnable {
private long maxCount = 0;// ⽂件的总⼤⼩
public long startTime = 0L;
private long uploaded = 0;
private boolean isScheduled = fal;
private Logger logger = Logger(SftpMonitor.class);
ScheduledExecutorService executorService;
public SftpMonitor(long maxCount) {
this.maxCount = maxCount;
}
@Override
public void run() {
NumberFormat format = PercentInstance();
format.tMaximumFractionDigits(2);
format.tMinimumFractionDigits(2);
日本电影大全String value = format.format((uploaded / (double) maxCount));
System.out.println("已传输：" + uploaded / 1024 + "KB，传输进度：" + value);
if (uploaded == maxCount) {
stop();
long endTime = System.currentTimeMillis();
System.out.println("传输完成！⽤时：" + (endTime - startTime) / 1000 + "s");
}
}
/**
* 输出每个时间段的上传⼤⼩
*/
@Override
public boolean count(long count) {
if (!isScheduled) {
createTread();
尊敬老师的故事}
uploaded += count;
// System.out.println("本次上传⼤⼩：" + count / 1024 + "KB,");
if (count > 0) {
return true;
}
return fal;
}
/**
* ⽂件上传结束时调⽤
*/
@Override
public void end() {
// System.out.println("⽂件传输结束");
}
/**
* ⽂件上传时开始调⽤
*/
@Override
public void init(int op, String src, String dest, long max) {
System.out.println("开始上传⽂件：" + src + "⾄远程：" + dest + "⽂件总⼤⼩:" + maxCount / 1024 + "KB");
startTime = System.currentTimeMillis();
}
/**
* 创建⼀个线程每隔⼀定时间，输出⼀下上传进度
*/
public void createTread() {
executorService = wSingleThreadScheduledExecutor();
// 1秒钟后开始执⾏，每2杪钟执⾏⼀次
executorService.scheduleWithFixedDelay(this, 1, 2, TimeUnit.SECONDS);
isScheduled = true;
}
/**
* 停⽌⽅法
*/
public void stop() {
boolean isShutdown = executorService.isShutdown();
if (!isShutdown) {
executorService.shutdown();
}
}
}
