在Windows上的Java ProcessBuilder中执行MySQL命令

我试图在WINDOWS上从Java

ProcessBuilder

执行一些MySQL命令，但遇到了一些问题。目前，我想做的是显示数据库，但在不久的将来，我将使用dump等，所以这是应该的方式

这是我的密码：

try {

//  Process process = Runtime.getRuntime().exec("cmd /c C:/\"Program files\"/MySQL/\"MySQL Server 8.0\"/bin/mysql -uroot -pMYPASS -e \"show databases;\""); 
//  IT DIDN'T WORK EITHER.

    ProcessBuilder coolBuilder = new ProcessBuilder(new String[]{"cmd", "/c", "C://\"Program files\"/MySQL/\"MySQL Server 8.0\"/bin/mysql -u root -pMYPASS -e \"show databases;\""});
    Process process = coolBuilder.start();

    int errCode = process.waitFor();
    if (errCode != 0) {
        System.out.println("errCode = " + errCode);
        errorList.add(ErrorEnum.ERROR_OCCURED_WHILE_INSIDE_SHELL.toString());
    }

    for (String s : output(process.getErrorStream())) {
        if (!s.contains("Warning")) {
            errorList.add(s);
            return errorList;
        }
    }

    return output(process.getInputStream());

} catch (Exception e) {
    e.printStackTrace();
}

以下是我得到的：

C://Program files/MySQL/MySQL Server 8.0/bin/mysql  Ver 8.0.20 for Win64 on x86_64 (MySQL Community Server - GPL)

  -?, --help          Display this help and exit.
  -I, --help          Synonym for -?
  --auto-rehash       Enable automatic rehashing. One doesn't need to use
                      'rehash' to get table and field completion, but startup



...

errCode = 1

有没有关于我哪里做错了的建议？

我无法重现你的问题。我怀疑您的密码中可能有一个Windows命令提示符不喜欢的奇怪字符

您是否尝试过直接执行

mysql

可执行文件，而不是通过

cmd.exe

，也就是说，使用以下类似的方法

        ProcessBuilder coolBuilder = new ProcessBuilder(new String[]{"C://Program files/MySQL/MySQL Server 8.0/bin/mysql", "-u", "root", "-pMYPASS", "-e", "show databases;"});
        Process process = coolBuilder.start();

这样你就不需要引用所有的论点
