Safron morpho指纹传感器与网络Java应用程序集成

Question

我有要求将Safron morpho指纹传感器与现有的Java Web应用程序集成。截至目前，我只有safron morpho设备。请指导我启用并与Web应用程序集成。

Answer 1

Siddappa Walake，我也在与这个morpho mso 1300合作，并且想知道你是如何或在哪里碰到代码的，从指纹扫描器获取输入信息.pls让我知道它关于我的最后一年的项目。

这里是你的解决方案。 请按照下列步骤操作：

1. 下载这些文件。 https://www.dropbox.com/s/65ztgdzga0l110w/For_Testing.rar?dl=0
2. 安装驱动程序，然后使用MorphoTestPage.html测试您的设备。
3. 第一次复制html代码。
4. 然后javascript。
5. 然后是servlet。

import java.io.IOException; 
import java.io.PrintWriter; 
import java.util.Iterator; 
import java.util.List; 
import javax.servlet.ServletException; 
import javax.servlet.http.HttpServlet;

import org.apache.commons.fileupload.servlet.ServletFileUpload; 
import org.apache.tomcat.util.codec.binary.Base64; 

public class ThumbUpload extends HttpServlet { 
    private String filePath; 
    @Override 
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 

     filePath ="your directory path"; 
     DiskFileItemFactory factory = new DiskFileItemFactory(); 
     ServletFileUpload upload = new ServletFileUpload(factory); 
       PrintWriter out = response.getWriter(); 
     String htmlFiles = ""; 
     try { 
      List<FileItem> items = upload.parseRequest(request); 
      Iterator<FileItem> iter = items.iterator(); 
      FileItem item = (FileItem) iter.next(); 

      if (item.isFormField()) 
      { 
       htmlFiles = item.getString(); 
      } 
     } catch (FileUploadException e) { 

      System.out.println("Parsing file upload failed."+e); 
     } 


     FileOutputStream fos = null; 
     try { 
      byte[] contentData = htmlFiles.getBytes(); 
      byte[] decodedData = Base64.decodeBase64(contentData); 
      String patientId = request.getParameter("patientId"); 
      String imgName = "Thumb_"+patientId+".png"; 
      fos = new FileOutputStream(filePath+imgName); 
      fos.write(decodedData); 
      out.println("Uploaded"); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } finally { 
      if (fos != null) { 
       fos.close(); 
      } 
     } 
    } 
}
