0 注意
- java的runtime不会加载系统的环境变量，需要自己手动设置，在.bat文件中
set path=C:\Program Files\R\R-3.4.2\bin
- java调用.bat时，当前路径是jar包上级目录或者是项目的根目录
1 出现cmd窗口
public static void runbat(String batPath) {
String cmd = "cmd /c start "+ batPath ;// pass
try {
Process ps = Runtime.getRuntime().exec(cmd);
ps.waitFor();
} catch (IOException ioe) {
ioe.printStackTrace();
}
catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("child thread donn");
}
2 不出现cmd窗口
public static void runBatWithoutCmd(String batPath) {
try {
Process ps = Runtime.getRuntime().exec(batPath);
InputStream in = ps.getInputStream();
int c;
while ((c = in.read()) != -1) {
}
in.close();
ps.waitFor();
} catch (IOException ioe) {
ioe.printStackTrace();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
