Safran morpho指纹传感器与web java应用程序集成

Question

我要求将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。请引导我启用并集成Web应用程序。

Answer 1

这是你的解决方案。请按以下步骤操作：

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 javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
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();
            }
        }
    }
}
