java - 从控制台窗口隐藏密码 Java Asterisk 密码或阻止显示输入的字符串

Question

public class Login {

    protected static String user, pass, host;
    Object conn;


    public void Login() throws SQLException
    {



    try {
      Class.forName ("com.mysql.jdbc.Driver");
    } catch (ClassNotFoundException e) {
        System.out.println ("Could not load the driver"); 
      }




    Scanner sc = new Scanner(System.in);
    Console console = System.console();

    System.out.println("Please Enter Username");
    user = sc.next();
    System.out.println("Please Enter Password");
    pass = sc.nextLine();
    System.out.println("Please Enter Host/IP Address");
    host = sc.next();
    System.out.println("Attempting Log In");



  Connection conn = (Connection) DriverManager.getConnection
                  ("jdbc:mysql://"+host+":3306/chessdb", user, pass);

只是一点帮助，一直在网上寻找阻止密码显示在控制台窗口上的方法。有没有一种简单的方法，要么完全不显示输入的文本，要么用星号仅覆盖密码字段的输入？

Answer 1

使用readPassword()方法。

而不是像使用扫描仪那样

System.out.println("Please Enter Password");
    pass = sc.nextLine();

用途:

    System.out.println("Please Enter Password");
    char[] passString = Console.readPassword();
    String pass = new String(passString );
