logon.java

用ssh作的一个小例子

package com.bluedot.usermanage.servlet;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.blue.manage.DAO.UserDAO;


 public class logon extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet {
   static final long serialVersionUID = 1L;
   
    
	public logon() {
		super();
	}   	
	@Override
	public void init() throws ServletException {
		System.out.println("chushihua");
	}
	
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		
	}  	
	
	
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
      String username = request.getParameter("username");
      String password = request.getParameter("password");
	   if(UserDAO.logon(username, password)){
			request.getRequestDispatcher("logonsuccess.jsp").forward(request, response);
	   }else{
		    request.setAttribute("tag","false");
			request.getRequestDispatcher("logon.jsp").forward(request, response);
	   }
	}   	  	    
}
