Use Apache Commons exec to implement the specified application to open the corresponding file

In the actual work, we sometimes need to specify an application, open a file. For example, open a MP3 music file with a player and open a text file with Notepad. Some applications, however, require some additional parameters, which should be noted in the specific use.

Package test.ffm83.commons.exec;

Import Org.apache.commons.exec.CommandLine;

Importorg.apache.commons.exec.DefaultExecutor;

Importorg.apache.commons.exec.ExecuteWatchdog;

Importorg.apache.commons.exec.PumpStreamHandler;

Importorg.apache.commons.io.output.ByteArrayOutputStream;

public class Easyexecfile {

publicstatic void Main (string[] args) {

Easyexecfileexec = new Easyexecfile ();

Exec.notepadreadfile ("D:/ffm83/ffm83.txt");

}

Publicvoid notepadreadfile (String filePath) {

Stringcommand = "notepad.exe" + FilePath;

try{

Bytearrayoutputstreamoutputstream = new Bytearrayoutputstream ();

Bytearrayoutputstreamerrorstream = new Bytearrayoutputstream ();

Command line Processing

Commandlinecommandline = commandline.parse (command);

Executing the body

Defaultexecutorexec = new Defaultexecutor ();

Exec.setexitvalues (NULL);

Using a watchdog to set timeouts

Executewatchdogwatchdog = new Executewatchdog (60000);

Exec.setwatchdog (watchdog);

Pumpstreamhandlerstreamhandler = new Pumpstreamhandler (

Outputstream,errorstream);

Exec.setstreamhandler (Streamhandler);

Exec.execute (commandline);//execution

Stringout = outputstream.tostring ("GBK");

Stringerror = errorstream.tostring ("GBK");

System.out.println (out);

SYSTEM.ERR.PRINTLN (Error);

}catch (Exception e) {

E.printstacktrace ();

}

}

}

After running, the corresponding TXT file is opened. After the file is closed, the process ends.
