今日目标：点击热词后携带此热词到servlet，再从数据库中找出论文的关键字中包含此热词的论文列表

 

今日总结：

package com.me.servlet;

import java.io.IOException;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;

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.me.dao.LWDao;
import com.me.domain.LunWen;

/**
* Servlet implementation class ClickServlet
*/
@WebServlet("/ClickServlet")
public class ClickServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
LWDao dao = new LWDao();

public ClickServlet() {
super();
// TODO Auto-generated constructor stub
}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String geunjian = request.getParameter("geunjian");
System.out.println(geunjian);
List<LunWen> guan = new ArrayList<LunWen>();
try {
guan = dao.login(geunjian);
} catch (SQLException e) {
e.printStackTrace();
}
for(int i=0;i<guan.size();i++) {
if(guan.get(i).getLianjie()!=null) {
String ss = guan.get(i).getLianjie().substring(6,guan.get(i).getLianjie().length());
guan.get(i).setLianjie("http://openaccess.thecvf.com/"+ss);
}

}
request.setAttribute("list", guan);
System.out.println(guan.size());
request.getRequestDispatcher("lw.jsp").forward(request, response);
}

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

}

 

明日目标：
