jna需要平台相关的DLL或so文件

直接写main方法调用，很正常

public static void main(String[] args) {
        File imageFile = new File("D:\\123.png");
        ITesseract instance = new Tesseract();  // JNA Interface Mapping
        // ITesseract instance = new Tesseract1(); // JNA Direct Mapping

        try {
            String result = instance.doOCR(imageFile);
            System.out.println(result);
        } catch (TesseractException e) {
            System.err.println(e.getMessage());
        }
    }

写在入口中就找不到值得的模块了

@At("/image")
@IocBean
public class ImageModule {

    @At("/number")
    @Ok("json")
    @AdaptBy(type=UploadAdaptor.class)
    public Object getNumber(@Param("file")TempFile tempFile){
        // 获取图片，解析图片
        File imageFile = new File("D:\\123.png");
        ITesseract instance = new Tesseract();  // JNA Interface Mapping
//         ITesseract instance = new Tesseract1(); // JNA Direct Mapping

        try {
            String result = instance.doOCR(tempFile.getFile());
            System.out.println(result);
        } catch (Exception e) {
            System.err.println(e.getMessage());
        }
        return tempFile.getName();
    }
}
