识别Java Scanner或控制台应用程序中的箭头键

[英]Recognize arrow keys in Java Scanner or Console application

原文 2016-03-07 19:43:21 5 1 java/ console/ java.util.scanner/ user-input

I am writing a Java application that uses both Scanner and Console to get input from the user. 我正在编写一个Java应用程序，它使用Scanner和Console来获取用户的输入。 I would like to add command history support so that the user can use the ARROW KEYS to search previous inputs (similar to a terminal). 我想添加命令历史记录支持，以便用户可以使用箭头键搜索以前的输入（类似于终端）。 Is there a way to do this? 有没有办法做到这一点？ Right now, when I use either the Scanner or the Console , I get weird symbols like ^[[A when pressing the arrow keys. 现在，当我使用Scanner或Console ，我得到奇怪的符号，如^[[A按箭头键时的^[[A

I have read about KeyListener and KeyEvent , but my application does not use a GUI. 我已经阅读了有关KeyListener和KeyEvent ，但我的应用程序没有使用GUI。

Thanks! 谢谢！

Good question - +1'd. 好问题 - + 1。 On Windows, I would SetConsoleMode to change the console to take raw input, but on *Nix it looks like there is more work involved. 在Windows上，我会使用SetConsoleMode来更改控制台以获取原始输入，但在* Nix上，它看起来更多涉及工作。 Unfortunately I don't have any code that I can show you right now, but have a look at this link and see if it helps. 不幸的是，我没有任何我现在可以向您展示的代码，但请查看此链接，看看它是否有帮助。
