在通过FTP使用ftp、get、put和delete文件时，我会随机地得到以下错误。

java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:339) - FTP删除- java.net.ConnectException:在java.net.PlainSocketImpl.socketConnect(原生方法)、在java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:200)、在java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:182)、在java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392)、在java.net.Socket.connect(Socket.java:579)在com.enterprisedt.util上拒绝连接。proxy.PlainSocket.createPlainSocket(PlainSocket.java:103) at com.enterprisedt.net.ftp.FTPControlSocket.newPassiveDataSocket(FTPControlSocket.java:946) at com.enterprisedt.net.ftp.FTPControlSocket.createDataSocketPASV(FTPControlSocket.java:854) at com.enterprisedt.net.ftp.FTPControlSocket.createDataSocket(FTPControlSocket.java:574) at com.enterprisedt.net.ftp.FTPClient.setupDataSocket(FTPClient.java:2572) at com.enterprisedt.net.ftp.FTPClient.initPut(FTPClient.java:2627) at comenterprisedt.net.ftp.FTPClient.putData(FTPClient.java:2700) at com.enterprisedt.net.ftp.FTPClient.putStream(FTPClient.java:2439) at com.enterprisedt.net.ftp.FTPClient.put(FTPClient.java:2407) at com.enterprisedt.net.ftp.FTPClient.put(FTPClient.java:2368) at org.pentaho.di.job.entries.ftpput.JobEntryFTPPUT.execute(JobEntryFTPPUT.java:812) at org.pentaho.di.job.Job.execute(Job.java:693)org.pentaho.di.trans.steps.jobexecutor.JobExecutor.executeJob(JobExecutor.java:238) at org.pentaho.di.trans.steps.jobexecutor.JobExecutor.processRow(JobExecutor.java:87) at org.pentaho.di.trans.step.RunThread.run(RunThread.java:60) at java.lang.Thread.run(Thread.java:745)
