执行的命令被称为CommandLine,可使用该类的addArgument()方法为其添加参数,parse()方法将你提供的命令包装好一个可执行的命令。命令是由执行器Executor类来执行的,DefaultExecutor类的execute()方法执行命令,exitValue也可以通过该方法返回接收。设置ExecuteWatchdog可指定进程在出错后多长时间结束,这样有效防止了run-away...

在Java中运行shell命令可以使用`Runtime`类或`ProcessBuilder`类来实现。这两种方法都可以在特定目录中执行shell命令。 1. 使用`Runtime`类: - 概...

JavaShell 解决方法 要解决Java执行shell命令无返回值的问题,可以通过以下两种方法: 使用ProcessBuilder类 ProcessBuilder类允许您在同一进程中执行命令,并获取命令执行的返回值。下面是一个使用ProcessBuilder类的示例: importjava.io.*;publicclassExecuteShellCommand{publicstaticvoidmain(String[]args){try{ProcessBuilderproc...
