使用包含address的路径执行进程

Question

我使用Runtime.getRuntime().exec()通过Java执行命令，但是我在运行命令的路径(带有空格)方面有问题。

我用"(双引号)括起了路径，也用'(单引号)尝试过，但失败了…:(:(:(:(

我的代码是

private void encryptFile(String csvFilePath) throws IOException {
    Process proc = Runtime.getRuntime().exec("gpg --recipient testKey2014 --output '" + csvFilePath + ".gpg' --encrypt '" + csvFilePath + "'");
    try {
        proc.waitFor();
    } catch (InterruptedException e) {
        System.out.println(e.getMessage());
    }
    BufferedReader stdInput = new BufferedReader(new InputStreamReader(proc.getInputStream()));
    BufferedReader stdError = new BufferedReader(new InputStreamReader(proc.getErrorStream()));
    String s = null;
    if (stdInput.ready()) {
        // read the output from the command
        System.out.println("Here is the standard output of the command:n");
        while ((s = stdInput.readLine()) != null) {
            System.out.println(s);
        }
    }
    if (stdError.ready()) {
        // read any errors from the attempted command
        System.out.println("Here is the standard error of the command (if any):n");
        while ((s = stdError.readLine()) != null) {
            System.out.println(s);
        }
    }
}

我也尝试了相同的字符串在我的终端，它执行得很好，但在这里，由于csvFilePath包含(空格)，这就是为什么命令不工作。

实际的命令是:

gpg --recipient testKey2014 --output '/home/avis/testDir/File Transfers/Recordings/PH2014050401/PH2014050401.zip.gpg' --encrypt '/home/avis/testDir/File Transfers/Recordings/PH2014050401/PH2014050401.zip'

输出为:

Here is the standard error of the command (if any):
usage: gpg [options] [filename]

谁有什么建议吗??

使用数组版本的exec:

Process proc = Runtime.getRuntime().exec(new String[]{"gpg",
                                                      "--recipient",
                                                      "testKey2014",
                                                      "--output",
                                                      csvFilePath + ".gpg",
                                                      "--encrypt"
                                                      csvFilePath});
