我想将简历生成为PDF。首先，通过获取用户的id来查看简历。下一步是将简历生成为PDF。
下面是servlet和SQLCommands.java的代码。我该怎么办？
的Servlet
package com.dls.csb.process.web.controller;
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.sql.Blob;
import java.sql.ResultSet;
import java.sql.SQLException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.dls.csb.utility.SQLOperations;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;
@WebServlet("/generateresume.html")
public class GenerateResume extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
int id = Integer.parseInt(request.getParameter("id"));
Document dc = new Document();
try {
ResultSet rs = SQLOperations.viewResume(id);
while (rs.next()) {
dc.open();
dc.add(new Paragraph(rs.getBlob("resume")));
dc.close();
}
}
catch (DocumentException de) {
de.printStackTrace();
}
catch (SQLException e) {
e.printStackTrace();
}
}
}
SQLCommands.java
package com.dls.csb.utility;
public interface SQLCommands {
String VIEW_RESUME ="select resume from account where id=?"
}
