无效的密钥代码@ java

Question

我正在研究一个用java自动输入内容的系统.这是我写它的方式:

public void typeMessage(String message) {
    for (char c : message.toCharArray()) {
        int code = c;
        if (code > 96 && code < 123) 
            code = code - 32;
        if (c == '@') {
            robot.keyPress(VK_SHIFT);
            robot.keyPress(VK_AT);
            robot.keyRelease(VK_SHIFT);
            robot.keyRelease(VK_AT);
        } else {
            type(code);
        }
    }
    type(VK_ENTER);
}

但是我收到了这个错误:

    Exception in thread "Thread-2" java.lang.IllegalArgumentException: Invalid key code

上

    robot.keyPress(VK_AT);

该类没有覆盖所有ascii字符,但可以解决您的问题,使其成本降低.

KeyboardKeys kk = new KeyboardKeys();

kk.keyPress( '@');

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent.*;
import static java.awt.event.KeyEvent.*;

public class KeyboardKeys {

private Robot robot;

public KeyboardKeys() throws AWTException {
    this.robot = new Robot();
}

public KeyboardKeys(Robot robot) {
    this.robot = robot;
}

public void keyPress(char characterKey){
