JNA全称Java Native Access,是一个建立在经典的JNI技术之上的Java开源框架(https://github.com/twall/jna)。JNA提供一组Java工具类用于在运行期动态访问系统本地库(native library:如Window的dll)而不需要编写任何Native/JNI代码。开发人员只要在一个java接口中描述目标native library的函数与结构,JNA将自动实现Java接口到native function的映射。

Native.load((Platform.isWindows() ? "msvcrt" : "c"),
CLibrary.class);
void printf(String format, Object... args);
}

CLibrary.INSTANCE.printf("Hello, World\n");
for (int i=0;i < args.length;i++) {
CLibrary.INSTANCE.printf("Argument %d: %s\n", i, args[i]);
}
}
}
