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.

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:
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.
