您必须签署 jar 文件。这就是我所做的，现在它正在工作。

有同样的问题，这里有人告诉这是必要的 

capturer.setPriority(DPFPCapturePriority.CAPTURE_PRIORITY_LOW);

调用 createCapture 解决后。我现在就试试这个答案。

您需要将 添加dptojni.jar到项目的库中，它位于c:/programs files/digital persona/bin/java. 或者您可以获取该类jniException并将其添加到您的项目中。

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
