JNA 使用

	public interface CLibrary extends Library {
		CLibrary INSTANCE = (CLibrary) Native.loadLibrary((Platform.isWindows() ? "msvcrt" : "c"), CLibrary.class);
		void printf(String format, Object... args);
	}

	public static void main(String[] 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]);
		}
	}

 

 

这是官方的一个解释：

JNA provides Java programs easy access to native shared libraries without writing anything but Java code - no JNI or native code is required. This functionality is comparable to Windows' Platform/Invoke and Python's ctypes.

 

可以轻松的调用本地的libraries,而不用编写任何java代码或native code
