在线求助，很急，为什么获取不到contnet值啊？
代码这样的：

import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.UUID;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.tt.model.Article;

/**
 * Servlet implementation class AddArticle
 */
public class AddArticle extends HttpServlet {
private static final long serialVersionUID = 1L;
       
    /**
     * @see HttpServlet#HttpServlet()
     */
    public AddArticle() {
        super();
        // TODO Auto-generated constructor stub
    }

/**
 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
 */
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
this.doPost(request, response);
}

/**
 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
 */
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String id = UUID.randomUUID().toString();
String date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date(System.currentTimeMillis()));
String title = request.getParameter("title");
String content = request.getParameter("content");
String tag = request.getParameter("tag");

Article article = new Article(id,date,title,content,tag);
article.save();
response.sendRedirect("/blog");
}
}

------解决方案--------------------
到底是content还是contnet，前台写错了把

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

// TODO Auto-generated method stub

String id = UUID.randomUUID().toString();

String date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date(System.currentTimeMillis()));
