这个错，是本人在做tess4j验证码解析时报错，网上也找了相关资料，没有获得答案，如下是我和同事摸索的排查过程；
PS：注意这个 只是本人排查的过程，并不适用于所有，也不保证正确性。
一、需要检查如下几个地方是否有这个问题，包含libtesseract304.dll（文件地址）；并将文件放入对应位置。
1、C:\Windows\SysWOW64 （64位系统）、C:\Windows\System32（32位系统）
2、jdk的bin目录，新建报错的文件夹，例如win32-x86-64，放入文件；我是：E:\TTM\Java\jdk1.8.0_161\bin\win32-x86-64
3、项目的代码目录，网上也有说 项目的bin目录，我是放tess4j的解析同级目录下的；
二、使用应用服务器（Tomcat ）来调用 验证码解析入口功能；
