java.lang.Runtime.getRuntime().exec(cmd)命令中参数不能用空格怎么办？

问题描述

项目中无法执行c程序，猜测是exec()函数的问题

String cmd= exe_path + ' ' +video + ' ' +host + ':' + port; Process process = runtime.exec(cmd);

问题解答

String[] cmd = new String[]{exe_path, video, host + ':' + port}回答2：

String[] cmd = {'/data/data/app_name/exename', '3' 'ip:port'};java.lang.ProcessBuilder builder = new java.lang.ProcessBuilder(cmd);java.lang.Process process = builder.start();int exitcode = process.waitFor();
