Answer 1

您需要将dptojni.jar添加到项目库中，它位于c:/programs files/digital persona/bin/java中。或者您可以获得课程jniException并将其添加到您的项目中。

Answer 2

遇到同样的问题，here是有人告诉必须把

capturer.setPriority(DPFPCapturePriority.CAPTURE_PRIORITY_LOW);

在调用createCapture来解决它之后。我现在会尝试这个答案。

Answer 3

您必须签署jar文件。这就是我所做的，现在它正在发挥作用。

Answer 4

确保在调用setCapturePriority方法之前已实例化DPFPCapture对象，并确保在使用完捕获对象后停止捕获
