从Java代码运行批处理文件

Question

我试图从我的Java可执行文件运行另一个目录中的批处理文件.我有以下代码:

    try {
        Process p =  Runtime.getRuntime().exec("cmd /c start \"C:\\Program Files\\salesforce.com\\Data Loader\\cliq_process\\upsert\\upsert.bat\"") ;           
    } catch (IOException ex) {
    }

结果是程序在运行程序的根目录中打开一个cmd窗口,并且不访问我提供的文件路径.

Answer 1

而不是Runtime.exec(String command),您需要使用exec(String command, String[] envp, File dir)方法签名:

Process p =  Runtime.getRuntime().exec("cmd /c upsert.bat", null, new File("C:\\Program Files\\salesforce.com\\Data Loader\\cliq_process\\upsert"));

但就个人而言,我会使用ProcessBuilder,这比使用和调试更加冗长但更容易Runtime.exec().

ProcessBuilder pb = new ProcessBuilder("cmd", "/c", "upsert.bat");
File dir = new File("C:/Program Files/salesforce.com/Data Loader/cliq_process/upsert");
pb.directory(dir);
Process p = pb.start();

Answer 2

尝试下面

try {
            String[] command = {"cmd.exe", "/C", "Start", "D:\\test.bat"};
            Process p =  Runtime.getRuntime().exec(command);           
        } catch (IOException ex) {
        }
