Java执行Shell&Command

主要使用Runtime和Process两个类其中如何对Process进行输入是关键尤其注意在合适的时候flush输出流

package shelltest;

import javaioBufferedReader;

import javaioIOException;

import javaioInputStreamReader;

import javaioOutputStreamWriter;

import javaioPrintWriter;

import javautilloggingLevel;

import javautilloggingLogger;

public class Shell {

private Process pro = null;

private Runtime runTime = null;

public Shell() {

runTime = RuntimegetRuntime();

if (runTime == null) {

Systemerrprintln(Create runtime false!);

Systemexit();

}

}

public void execueteCommand(String command) throws InterruptedException {

Systemoutprintln(************************);

Systemoutprintln(Execute command :+command);

Systemoutprintln(Result:);

try {

pro = runTimeexec(command);

BufferedReader input = new BufferedReader(new InputStreamReader(pro getInputStream()));//这个输入流是获取shell输出的

PrintWriter output= new PrintWriter(new OutputStreamWriter(progetOu tputStream()));//这个输出流主要是对Process进行输入控制用的

String line;

while ((line = inputreadLine()) != null) {

Systemoutprintln(line);

if( != lineindexOf(your name)){//当检测到提示输入时则执行输入操作

outputprint(liuwei\r\n);// \r\n 不可少否则相当于没有Enter操作

outputflush();//输入完成之后一定要flush否则一直处在等待输入的地方

}

}

Systemoutprintln(************************\n);

inputclose();

outputclose();

prodestroy();

} catch (IOException ex) {

LoggergetLogger(ShellclassgetName())log(LevelSEVERE null ex);

}

}

}
