1、java.lang.UnsatisfiedLinkError: Unable to load library 'tesseract': Native library (linux-x86-64/libtesseract.so) not found in resource path
和 at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:303) ~[jna-4.5.2.jar!/:4.5.2 (b0)]
解決方法：
你需要在centos 安裝一些圖像的包 yum -y install libjpeg* libpng* freetype* gd* giflib* libtiff* zlib* 然后安裝tesseract包 yum install tesseract
安裝之后，需要讓程序調用，所以要暴露出來
通過rpm -qal | grep tesseract 查找安裝的文件
命令打開這個文件，vim ~/.bash_profile
添加下面兩個
LD_LIBRARY_PATH=/usr/lib64/
export LD_LIBRARY_PATH
再運行source ~/.bash_profile 使文件生效
2、碰到這種錯誤，那就是你的內存不足了，換機器或者添加內存吧
