我解决了这个问题。我所做的只是将这些行粘贴到java.policy文件中（只需在Java安装文件夹中搜索此文件，您将在3个位置得到它，最后需要将其粘贴到所有文件中）
permission java.awt.AWTPermission "createRobot"; permission java.awt.AWTPermission "accessClipboard"; permission java.awt.AWTPermission "accessEventQueue"; permission java.awt.AWTPermission "showWindowWithoutWarningBanner"; permission java.awt.AWTPermission "readDisplayPixels", "read"; permission java.io.FilePermission "<<ALL FILES>>", "read, write, delete, execute";
