用Java发送斜杠和反斜杠

使用Java robot时，发送斜杠或反斜杠时会引发异常

例如：

public void slash() throws AWTException {
    Robot rob = new Robot();
    rob.keyPress(KeyEvent.VK_SLASH);
    rob.keyRelease(KeyEvent.VK_SLASH);
}

public void backSlash() throws AWTException {
    Robot rob = new Robot();
    rob.keyPress(KeyEvent.VK_BACK_SLASH);
    rob.keyRelease(KeyEvent.VK_BACK_SLASH);
}

然后，当我想输入这些时，我使用：

public void type() {

    try {
        slash();
    } catch (AWTException e) { System.out.println("Exception when typing slash."); }

    try {
        backSlash();
    } catch (AWTException e) { System.out.println("Exception when typing back slash."); }


}

我在控制台中收到两条错误消息。顺便说一下，我尝试发送的所有其他按键都很好

我得到了斜杠的如下堆栈跟踪：

反斜杠起作用，但也会抛出一个IllegalArgumentException：

有什么方法可以发送斜杠和反斜杠按键吗？

（很抱歉，我应该提到这不是一个很好的答案，只是说它确实对我有用，所以我猜这是一个配置问题或其他问题——但我认为其他人可能会觉得这很方便。这应该是一个注释，但出于技术原因，我必须将其作为一个答案）

我没有搞乱Robot类，只是花了半个小时的时间在这个很酷的java类上乱搞和构建一些东西

对于我来说，发送斜杠和反斜杠很好。因为VK_？？？东西很好地映射到ASCII字符，所以可以发送“\”或“/”，它也应该可以工作

我使用Groovy是因为这正是我现在所做的，但这里有一个很好的例子和我刚想到的一堆可重用代码。它是作为脚本编写的，但可以很容易地转换为Groovy或Java中的类（我很快就会这样做）

这必须从“私有”shell运行（例如，右键单击命令提示符并选择“以管理员身份运行”）

此外，它必须有时间让您放开键盘！（这是一个艰难的过程），因此，如果您使用groovyShell并使用alt-r运行它，请确保在发送第一个键之前延迟1秒，否则alt将成为按下的键的一部分

import java.awt.* import java.awt.event.* import static java.awt.event.KeyEvent.* r=new Robot() r.autoWaitForIdle = true r.autoDelay=200 // Usually works with 0 but sometimes that's too fast. // This will alt-tab you to your "Previous" app. While testing I edited this in notepad++ // then tabbed out to a shell to execute it, this tabbed back into my editor and typed // the "test" text. alt VK_TAB send "backslash=\\ \nforward slash =/" // This will send any string def send(String s) { def difference = ("a" as Character) - ("A" as Character) s.each { Character c=it as Character if(c.isUpperCase()) { shift c } else if(c.isLowerCase()) { send(c - difference) } else send(c) } } // These will work for integers and chars, NOT strings def send(key) { press(key as Integer) release(key as Integer) } def alt(key) { press VK_ALT send key release VK_ALT } def shift(key) { press VK_SHIFT send key release VK_SHIFT } def press(key) { r.keyPress(key as Integer) } def release(int key) { r.keyRelease(key as Integer) } 导入java.awt* 导入java.awt.event* 导入静态java.awt.event.KeyEvent* r=新机器人（） r、 autoWaitForIdle=true r、 autoDelay=200//通常与0一起工作，但有时速度太快。 //这会将你切换到你的“上一个”应用程序。测试时，我在记事本中编辑了这个++ //然后切换到一个shell来执行它，这个切换回到我的编辑器中并键入 //“测试”文本。 alt VK_选项卡 发送“反斜杠=\\\n前斜杠=/” //这将发送任何字符串 def发送（字符串s） { 定义差异=（“a”作为字符）-（“a”作为字符） s、 各{ 字符c=它作为字符 if（c.isUpperCase（））{ 移位c }else if（c.isLowerCase（））{ 发送（c-差异） } 其他发送（c） } } //这些将适用于整数和字符，而不是字符串 def发送（键） { 按（键为整数） 释放（键为整数） } def alt（键） { 按VK_ALT 发送密钥 释放VK_ALT } def换档（钥匙） { 按下VK_SHIFT键 发送密钥 释放VK_移位 } def按下（键） { r、 按键（键为整数） } def释放（int键） { r、 键释放（键为整数） }

好的，我找到了一个解决方案，它使用Alt代码，对于使用不同键盘布局的用户来说可能很方便

public static void alt(int event1, int event2, int event3, int event4) throws Exception {

    Robot bot = new Robot();
    bot.delay(50); //Optional
        bot.keyPress(KeyEvent.VK_ALT);

            bot.keyPress(event1);
            bot.keyRelease(event1);

            bot.keyPress(event2);
            bot.keyRelease(event2);

            bot.keyPress(event3);
            bot.keyRelease(event3);

            bot.keyPress(event4);
            bot.keyRelease(event4);

        bot.keyRelease(KeyEvent.VK_ALT);

}

然后你这样称呼它：

对于反斜杠：

alt（KeyEvent.VK_NUMPAD0、KeyEvent.VK_NUMPAD0、KeyEvent.VK_NUMPAD9、KeyEvent.VK_NUMPAD2）；

对于普通的：

alt（KeyEvent.VK_NUMPAD0、KeyEvent.VK_NUMPAD0、KeyEvent.VK_NUMPAD4、KeyEvent.VK_NUMPAD7）；

没有例外。

也适用于所有其他字符。但请确保在使用此选项时启用Num Lock。

请始终包含

e.printStackTrace（）的结果

适用时。与其打印出异常，不如打印出异常详细信息？其他击键是否有效，或者只是斜杠和反斜杠正在中断？计算机上有什么语言环境？如果您可以将OS/JVM构建和版本详细信息添加到问题中，那也太好了，因为这些可能与问题有关。（这两种方法在64位Windows 7、Java 7u7上执行时没有例外）.1，创造性思维。如果这是您的最终解决方案，请将其标记为已接受。不过，为了改进，不要在每次调用该方法时都使用新的

机器人。这是我的最终解决方案，但网站不允许我选择，它说我必须等待2天；我会等待，然后选择。
