JAVA代码模拟键盘操作
好的,以下是使用Java的JNA来模拟键盘操作的示例代码:
首先,需要引入JNA依赖:
```xml
<dependency>
<groupId>net.java.dev.jna</groupId>
<artifactId>jna</artifactId>
<version>5.7.0</version>
</dependency>
```
然后,可以编写一个Keyboard类,封装键盘模拟操作:
```java
import com.sun.jna.platform.win32.User32;
import com.sun.jna.platform.win32.WinDef;
import com.sun.jna.platform.win32.WinUser;
public class Keyboard {
private static final int KEYEVENTF_EXTENDEDKEY = 0x0001;
private static final int KEYEVENTF_KEYUP = 0x0002;
private static final int VK_SHIFT = 0x10;
private static final int VK_CONTROL = 0x11;
private static final int VK_MENU = 0x12;
private static final int VK_LWIN = 0x5B;
private static final int VK_RWIN = 0x5C;
private static final User32 user32 = User32.INSTANCE;
public static void pressKey(int keyCode) {
user32.keybd_event((byte)keyCode, (byte)0, KEYEVENTF_EXTENDEDKEY, null);
}
public static void releaseKey(int keyCode) {
user32.keybd_event((byte)keyCode, (byte)0, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, null);
}
public static void typeKey(int keyCode) {
pressKey(keyCode);
releaseKey(keyCode);
}
public static void typeText(String text) {
for (char c : text.toCharArray()) {
if (Character.isUpperCase(c)) {
pressKey(VK_SHIFT);
}
typeKey(Character.toUpperCase(c));
if (Character.isUpperCase(c)) {
releaseKey(VK_SHIFT);
}
}
}
public static void pressCtrlAltDelete() {
pressKey(VK_CONTROL);
pressKey(VK_MENU);
typeKey(0x2E);
releaseKey(VK_CONTROL);
releaseKey(VK_MENU);
}
public static void pressWindowsKey() {
pressKey(VK_LWIN);
releaseKey(VK_LWIN);
}
}
```
这个类提供了几个常用的键盘模拟操作函数,如pressKey()、releaseKey()、typeKey()和typeText(),可以用来模拟按键和输入文本。其中,pressCtrlAltDelete()和pressWindowsKey()分别用来模拟Ctrl+Alt+Delete和Win键的按下。
最后,可以编写一个测试程序,来测试键盘模拟操作是否正常:
```java
public class KeyboardTest {
public static void main(String[] args) {
Keyboard.typeText("Hello, World!");
Keyboard.pressCtrlAltDelete();
Keyboard.pressWindowsKey();
}
}
```
这个测试程序会依次模拟输入文本、按下Ctrl+Alt+Delete和Win键。运行程序后,可以观察到相应的键盘操作效果。
