这是因为在Java中执行shell命令是通过新的进程来执行的,因此在主进程中获取不到命令执行的返回值。 代码示例 importjava.io.*;publicclassExecuteShellCommand{publicstaticvoidmain(String[]args){try{Processprocess=Runtime.getRuntime().exec("ls");BufferedReaderreader=newBufferedReader(newInputStreamReader(proces...
run.exec(cmd)调用的是RunTime下的方法,代码如下 publicProcess exec(String command)throwsIOException {returnexec(command,null,null); } 进而调用(我们只需看最后一行) publicProcess exec(String command, String[] envp, File dir)throwsIOException {if(command.length() == 0)thrownewIllegalArgumentException(...
I'm trying to create a program allowing me to execute a command through a terminal (which is OmxPlayer for raspberry pi if you want to know) with arguments, but i'd want to be able to interact with it once I have launched the command. For example i'd want to do : omxplayer -...

Commons Exec的核心是Executor接口,它定义了执行外部命令的方法。DefaultExecutor类是这个接口的一个实现,提供了执行外部命令的基本功能。使用CommandLine类,咱们可以方便地构建需要执行的命令和参数。而ExecuteResultHandler接口则允许咱们处理异步执行的命令的结果。
