虽然很想休息,但是想想还是要把今天学的东西记下来,不然以后再用还是新知识。
新建一个线程类读取子进程的汇报信息和错误信息,避免阻塞
class StreamGobbler extends Thread
{
InputStream is;
String type;
StreamGobbler(InputStream is, String type)
{
this.is = is;
this.type = type;
}
public void run()
{
try
{
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line=null;
while ( (line = br.readLine()) != null)
System.out.println(type + ">" + line);
} catch (IOException ioe)
{
ioe.printStackTrace();
}
}
}
创建子进程的RUN方法
//cmd命令
String s = "I:/OpenModelica-v1.9.7/bin/omc.exe "+courseFile+"/modelica/tcs.mos";
//执行cmd命令
Process proc = Runtime.getRuntime().exec(s);
//接收子进程的汇报信息和错误信息,避免阻塞
new StreamGobbler(proc.getInputStream(),"INFO").start();
new StreamGobbler(proc.getErrorStream(),"ERROR").start();
//获取子进程执行结果状态
int status=proc.waitFor();
if (status == 0){
System.out.println(n+"执行完毕");
detect(n);
}else
System.out.println(n+"执行失败");
//销毁子进程
proc.destroy();
