java 调用cmd交互式执行命令并获得执行结果

我是靠谱客的博主沉静酒窝，这篇文章主要介绍java 调用cmd交互式执行命令并获得执行结果，现在分享给大家，希望可以做个参考。

需求是这样：需要调用cmd执行某个位置下的可执行程序，（具体我这里是gtsstp.exe），首先可以通过Process的getOutputStream向其输入命令，然后用InputStreamReader获得执行结果。
这里需要注意的是：因为读取执行结果时是按行读取br.readLine()，所以在需要输入命令时，一定要newline()新加一行，否则不能继续往下读取后面的内容！！！

代码块

代码如下：

复制代码

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
public class Cmd {
Process process;
public void CmdTest() throws IOException {
process=Runtime.getRuntime().exec("cmd");
new Thread(){
public void run() {
try {
BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(process.getOutputStream()));
bw.write("e:");
bw.newLine();
bw.write("cd E:\Code\AltaRicaWizard");
bw.newLine();//因为读取时是一行行读取的，不加newline无法继续往下读
bw.write("gtsstp.exe GTS.xml");
bw.newLine();
bw.write("print tr");
bw.newLine();
bw.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}.start();;
new Thread() {
public void run() {
try {
BufferedReader br=new BufferedReader(new InputStreamReader(process.getInputStream()));
String cmdout="";
while ((cmdout=br.readLine())!=null) {
System.out.println(cmdout);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}.start();
}
public static void main(String[] args) throws IOException {
Cmd cmd=new Cmd();
cmd.CmdTest();
}
}
