java.lang.IllegalAccessError:尝试从类Tess4jTest.TestTess访问方法net.sourceforge.tess4j.Tesseract.< init>()V [英] java.lang.IllegalAccessError: tried to access method net.sourceforge.tess4j.Tesseract.<init>()V from class Tess4jTest.TestTess

问题描述

我在Mirth中用Tesseract做了一个Java OCR项目.当我从Mirth运行jar文件时，出现此错误.当我搜索它时，发现有一个init()方法.而且它在Tesseract.java中是一个受保护的空位.我认为这可能是该错误的原因. 我该怎么办?非常感谢您的帮助.

I did a Java OCR project with Tesseract in the Mirth.When I run the jar file from the Mirth,I get this error.When I search it,I found that there is a init() method and also it is a protected void in Tesseract.java.I think that maybe it is the reason for that error. What should I do?Thank you so much for your helps.

package Tess4jTest;

import java.io.File;
import java.io.IOException;
import net.sourceforge.tess4j.*;

public class TestTess {

public static String Tc;
public static String phone;
public static String date;


public static void main(String[] args) {
    //System.out.println(returnText("C:\\Users\\Nevzat\\Desktop\\deneme.pdf"));
}

public static String returnText(String fileName){

    File imageFile = new File(fileName);
    if(imageFile.exists()){
        Tesseract instance = new Tesseract();
        instance.setDatapath("C:\\imageRAD\\Onam\\tessdata");
        String result = null;
        try {
            result = instance.doOCR(imageFile);
        } catch (TesseractException e) {
            System.err.println(e.getMessage());
        }
        if(result!=null){

            int i=result.indexOf("Numarasn: ");
            int j=result.indexOf("Tel No:");
            int k=result.indexOf("Bilgllendirme Tarihl:");

            Tc = result.substring(i+10, i+21);
            phone = result.substring(j+8,j+23);
            date = result.substring(k+22,k+32);
            //System.out.println(result);
        }else{
            return "Null Error!";
        }

    }else{
        return "Does not found a file!";
    }

    return Tc+","+phone+","+date;
}

public static String returnTC() throws IOException{
    return Tc;
}

public static String returnPhone() throws IOException{
    return phone;
}

public static String returnDate() throws IOException{
    return date;
}

}

推荐答案

当您尝试使用私有构造函数创建对象时，会发生错误. (<init>()是没有参数的构造函数的名称)

The error you got occurs when you try to create an object with a private constructor. (<init>() is the name of a constructor with no parameters)

在tess4j源代码中，我找到了具有以下文档的方法:

Looking at the tess4j source I found a method with the following documentation:

• @deprecated从2.0版开始，请改用默认构造函数.

• @deprecated As of Release 2.0, use default constructor instead.

在2.0之前的源代码中发现默认构造函数是private.

Looking at the source before 2.0 reveals the default constructor was private.

这意味着您的问题很可能是针对2.0版以上的版本进行编译的，但是您的环境运行的是2.0版之前的版本.

This means your problem is most likely that you are compiling against a version newer than 2.0, but your environment is running one older than 2.0.

要么更新您的环境，要么降级您​​要构建的库以对其进行修复.

Either update your environment or downgrade the library you build against to fix it.
