我正在尝试为我的java应用程序使用全局热键。我搜索了很多，最后决定使用JIntellitype。我了解到它使用JNI与操作系统交互。我已经从https://code.google.com/p/jintellitype/downloads/list下载了JIntelliType API
我已经将jar包含在我的项目中，它显示在(Project_name) ->(引用库)-> jintellitype_1.3.9.jar .我是否正确导入了它?
我已经编写了下面的示例程序来测试它import com.melloware.jintellitype.HotkeyListener;
import com.melloware.jintellitype.JIntellitype;
public class Example1 {
public static void main() throws Exception
{
System.out.println("Line 1");
//JIntellitype.getInstance().registerHotKey(1, JIntellitype.MOD_WIN, (int)'A');
//JIntellitype.getInstance().registerHotKey(2, JIntellitype.MOD_ALT + JIntellitype.MOD_SHIFT, (int)'B');
hkey h=new hkey();
h.init_hotkey();
Thread.sleep(100);
}
}
class hkey
{
void init_hotkey()
{
System.out.println("line 2");
JIntellitype.getInstance();
JIntellitype.getInstance().registerHotKey(1, JIntellitype.MOD_WIN, (int)'A');
JIntellitype.getInstance().addHotKeyListener(new HotkeyListener() {
@Override
public void onHotKey(int arg0) {
// TODO Auto-generated method stub
if (arg0 == 1)
System.out.println("WINDOWS+A hotkey pressed");
}
});
}
}
显示没有错误或警告。但是"line 1"one_answers"line 2"这两行没有被打印出来。我的控制台显示我运行后。
JIntellitype version "1.3.9"
Running on java version "1.7.0_55" (build 1.7.0_55-b13) from Oracle Corporation
Operating environment "Windows 7" version 6.1 on x86

是代码有问题还是我没有正确导入?有关于jintellittype的任何示例程序吗?这里有一个https://code.google.com/p/jintellitype/downloads/list，但其中没有.java文件。它在其中编译了.class文件。
我的问题解决了。我必须把DLL文件添加到项目中。
(项目名)->引用库-> jintellitype-1.3.9 ->属性->本地库->给出DLL文件所在的路径。
可以在这里查看jintellittype的示例https://code.google.com/p/jintellitype/source/browse/trunk/src/test/java/com/melloware/JIntellitypeTester.java
