我试过在Eclipse中使用Tess4J，但结果导致标题错误。我导入了以下jar文件：tess4j，jai_imageio和jna。我编写的测试代码按照其示例页面上给出的示例进行。
File DMTfile = new File(System.getProperty("user.dir")+"\\DMTcap.bmp");
BufferedImage DMTcap = ImageIO.read(DMTfile);Tesseract instance = new Tesseract();
String result = "";
try {
result = instance.doOCR(DMTcap);
} catch (TesseractException e2) {
e2.printStackTrace();
}
System.out.println(result);
完整错误如下：

我怎样才能解决这个问题？
最佳答案
Platform.RESOURCE_PREFIX是JNA常量。确保使用适当版本的JNA（4.1.0）。
还要检查这篇文章中的答案：NoSuchFieldError: RESOURCE_PREFIX with a maven project using tess4j
关于java - NoSuchFieldError:将Tess4J与Eclipse一起使用时，RESOURCE_PREFIX，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/33080638/
