java中调用cmd命令

在项目中使用到这方面的，备忘一下！

String cmdo = “chmod 777 start.sh”;

String inputtxt = file.getAbsolutePath() + File.separator + “input.txt”;

String outputtxt = file.getAbsolutePath() + File.separator + “output.txt”;

//首先要构建命令

String cmd = “sh start.sh –inputPath=” + inputtxt + ” –outputPath=” + outputtxt;//在Linux系统中

//构建执行文件夹

//这里为传进来的文件

BufferedReader stdInput = null;

BufferedReader stdError = null;

try {

logger.debug(“开始执行cmdo命令：” + cmd + “执行路径：” + file.getAbsolutePath());

Process execo = Runtime.getRuntime().exec(cmdo, null, file);

execo.waitFor();

logger.debug(“开始执行cmd命令：” + cmd + “执行路径：” + file.getAbsolutePath());

Process exec = Runtime.getRuntime().exec(cmd, null, file);

String s = null;

stdInput = new BufferedReader(new InputStreamReader(exec.getInputStream(), StandardCharsets.UTF_8));

stdError = new BufferedReader(new InputStreamReader(exec.getErrorStream(), StandardCharsets.UTF_8));

while ((s = stdInput.readLine()) != null) {

logger.error(s);

}

while ((s = stdError.readLine()) != null) {

logger.error(s);

}

int resulStatus = exec.waitFor();

if (resulStatus != 0) {

throw new Exception(“执行shell脚本出错了”);

}

logger.debug(“执行完shell脚本”);

} catch (InterruptedException e) {

logger.debug(“发生异常了1”);

} catch (Exception e) {

logger.debug(“发生异常了2”);

throw new Exception(“执行shell脚本出错了”);

} finally {

IOUtils.closeQuietly(stdInput);

IOUtils.closeQuietly(stdError);

}
