        ITesseract instance = new Tesseract();
        // 指定训练数据集合的路径
        instance.setDatapath("/Users/js/Desktop/tessdata-main");
        // 指定为中文识别
        instance.setLanguage("chi_sim");

原因是mac jar加载不了dylib依赖。

 

可手动将dylib依赖打包进jar

通过macports安装Tesseract

  • sudo port install Tesseract

将libtesseract.dylib加入jar包

libtesseract.dylib可通过find / -name 查找位置

  • mkdir darwin
  • jar uf tess4j-xxx.jar darwin
  • cp libtesseract.4.dylib darwin/libtesseract.dylib
  • jar uf tess4j-xxx.jar darwin/libtesseract.dylib
  • jar tf tess4j-xxx.jar

pom依赖本地jar

        <dependency>
            <groupId>net.sourceforge.tess4j</groupId>
            <artifactId>tess4j</artifactId>
            <version>4.5.1</version>
            <scope>system</scope>
            <systemPath>${basedir}/src/main/resources/jar/tess4j-4.5.1.jar</systemPath>
        </dependency>

启动报错

Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/jna/Structure
    at com.eu.ocr.TextOcr.main(TextOcr.java:16)
Caused by: java.lang.ClassNotFoundException: com.sun.jna.Structure

    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:352)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:351)

解决：将Tess4j文件下的lib下的jar添加项目依赖

 

 识别成功
