无法在Centos7上制作tesseract作品

Question

我正在开发一个在Eclipse中使用Java Sprint和Maven的应用程序。

我使tesseract在我的开发机器上工作在Windows中（是的，我知道...），但是当我尝试在服务器上部署应用程序是Centos 7时，出现一些错误，应用程序停止工作。 ..

pom.sml

<dependency> 
    <groupId>org.bytedeco.javacpp-presets</groupId> 
    <artifactId>tesseract-platform</artifactId> 
    <version>3.04.01-1.3</version> 
</dependency> 

我的代码：

BytePointer outText; 
       TessBaseAPI api = new TessBaseAPI(); 

       if (api.Init(ResourcesLocation.getTestData(), "spa") != 0) { 
        System.err.println("Could not initialize tesseract."); 
        response.setSuccess(false); 
        response.setCode(CodeList.EXCEPTION); 
       } 
       else{ 
        // Open input image with leptonica library 
        PIX image = pixRead(file); 
        api.SetImage(image); 
        // Get OCR result 
        outText = api.GetUNLVText(); 

        data = this.cleanData(outText.getString().split("\\r?\\n")); 
        // Destroy used object and release memory 
        api.End(); 
        outText.deallocate(); 
        pixDestroy(image); 
       } 
       api.close(); 

和运行过程中出现了：

我安装了正方体和Leptonica以下this example（但我改变了lenguage西班牙）

我可以从有这样做时，应用程序崩溃：

TessBaseAPI api = new TessBaseAPI(); 

Answer 1

的最终解决方案这是为了执行包括dessire params在内的tesseract，并将结果写入文本文件，从Java应用程序运行命令。之后，Java应用程序读取文本文件，这就是全部！

没有API，没有外部库，没有更多的问题...
