Java模拟键盘输入（Robot类模拟键盘输入，解决不准粘贴）

1.背景

  主要也是为了偷懒，老师不准粘贴。但是提供的测试环境又很不友好，自己敲了一份还要再敲就很烦。于是就写了这个。只能模拟英文和字符输入，中文会直接跳过。点击开始模拟输入会在5秒钟后开始模拟输入。

2.代码

1. TypeRobot。用Robot来模拟输入的类，挺简单就不多讲了。如果你还需要输入其他字符，参考Java 键盘上各个按键的KeyCode值。

import java.awt.Robot;public class TypeRobot {private Robot robot;private int delay;//传入一个Robot对象public TypeRobot(Robot robot) {this.robot = robot;}//第二个参数是延时TypeRobot(Robot robot, int delay) {this.robot = robot;this.setDelay(delay);}void typeLowerCase(char c) {robot.keyPress(c-32);robot.keyRelease(c-32);delay();}void typeUpperCase(char c) {robot.keyPress(16);robot.keyPress(c);robot.keyRelease(16);robot.keyRelease(c);delay();}void typeNumber(char c) {robot.keyPress(c);robot.keyRelease(c);delay();}void typeOther(char c) {switch(c) {case '+':pressKeyWithCtrl(61);break;case '-':pressKey(45);break;case '*':pressKeyWithCtrl(56);break;case '/':pressKey(47);break;case '\'':pressKey(222);break;case ':':pressKeyWithCtrl(59);break;case '{':pressKeyWithCtrl(91);break;case '}':pressKeyWithCtrl(93);break;case '[':pressKey(91);break;case ']':pressKey(93);break;case ';':pressKey(59);break;case '#':pressKeyWithCtrl(51);break;case '!':pressKeyWithCtrl(49);break;case '%':pressKeyWithCtrl(53);break;case '&':pressKeyWithCtrl(55);break;case '=':pressKey(61);break;case ' ':pressKey(32);break;case '	':pressKey(9);break;case '\n':pressKey(10);break;case '<':pressKeyWithCtrl(44);break;case '>':pressKeyWithCtrl(46);break;case '?':pressKeyWithCtrl(47);break;case '.':pressKey(46);break;case '"':pressKeyWithCtrl(222);break;case '(':pressKeyWithCtrl(57);break;case ')':pressKeyWithCtrl(48);break;case '\\':pressKey(92);break;case ',':pressKey(44);break;case '@':pressKeyWithCtrl(50);break;case '|':pressKeyWithCtrl(92);break;case '^':pressKeyWithCtrl(54);break;case '_':pressKeyWithCtrl(45);break;}}public void setDelay(int delay) {this.delay = Math.max(delay, 0);}public int getDelay() {return delay;}private void delay() {robot.delay(delay);}private void pressKeyWithCtrl(int key) {robot.keyPress(16);robot.keyPress(key);robot.keyRelease(key);robot.keyRelease(16);delay();}private void pressKey(int key) {robot.keyPress(key);robot.keyRelease(key);delay();}
}

2. Window。窗口类。

}

3. Main。启动类。

import java.awt.Dimension;public class Main {public static void main(String[] args) {new Window("TypeRobot", new Dimension(500, 500));}
}
