Question

我正在使用Runtime.getRuntime().exec()通过Java执行命令，但是我遇到有关运行命令的路径（带空格）的问题。

我用"（双引号）封闭了路径，并尝试使用'（单引号），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);
        }
    }
}

我也在我的终端中尝试了相同的字符串并且执行正常，但是由于csvFilePath包含（空格），这就是命令无效的原因。

实际命令是：

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

OUTPUT是：

Here is the standard error of the command (if any):

usage: gpg [options] [filename]

有人建议做什么???

只需使用array version of exec：

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

使用包含地址的路径执行Process
