Ganymed SSH2 remote interactive Command Execution tool that simulates putty, ganymedputty

Next, I will introduce http://blog.csdn.net/doctor_who2004/article/details/47322105:

We simulate remote commands such as putty:

Import java. io. bufferedReader; import java. io. IOException; import java. io. inputStreamReader; import java. io. printWriter; import java. nio. charset. standardCharsets; import java. util. imports; import java. util. concurrent. executorService; import java. util. concurrent. executors; import java. util. concurrent. timeUnit; import org. apache. commons. io.

Here, I operate read and write streams in different threads to prevent blocking between read and write streams and simulate the interaction environment. Of course, you are logged on to the local system and have not installed virtual machines.
