Having spaces in Runtime.getRuntime().exec with 2 executables
提问by pwatt01
I have a command that I need to run in java along these lines:
我有一个命令，我需要在 java 中沿着这些行运行：
C:\path\that has\spaces\plink -arg1 foo -arg2 bar "path/on/remote/machine/iperf -arg3 hello -arg4 world"
This command works fine when the path has no spaces, but when I have the spaces I cannot seems to get it to work. I have tried the following things, running Java 1.7
当路径没有空格时，此命令工作正常，但是当我有空格时，我似乎无法让它工作。我尝试了以下操作，运行 Java 1.7
String[] a = "C:\path\that has\spaces\plink", "-arg1 foo", "-arg2 bar", "path/on/remote/machine/iperf -arg3 hello -arg4 world"
Runtime.getRuntime().exec(a);
as well as
也
String[] a = "C:\path\that has\spaces\plink", "-arg1 foo", "-arg2 bar", "path/on/remote/machine/iperf", "-arg3 hello", "-arg4 world"
Runtime.getRuntime().exec(a);
But neither seem to be doing anything. Any thoughts on what i am doing wrong??
但两者似乎都没有做任何事情。关于我做错了什么的任何想法？

Each argument you pass to the command should be a separate String element.
您传递给命令的每个参数都应该是一个单独的 String 元素。
So you command array should look more like...
所以你的命令数组应该看起来更像......
String[] a = new String[] {
"C:\path\that has\spaces\plink",
"-arg1",
"foo",
"-arg2",
"bar",
"path/on/remote/machine/iperf -arg3 hello -arg4 world"};
Each element will now appear as a individual element in the programs argsvariable
每个元素现在将作为一个单独的元素出现在程序args变量中
I would also, greatly, encourage you to use ProcessBuilderinstead, as it is easier to configure and doesn't require you to wrap some commands in "\"...\""
我也非常鼓励你改用ProcessBuilder它，因为它更容易配置并且不需要你在其中包装一些命令"\"...\""
