问题描述
这是我的jsp页面
<html>
<head>
<link rel = "stylesheet" href="main.css"/>
<title>Login Page</title> </head>
<body>
<div class ="RegWrap">
<div class ="Set">
<form name="actionForm" action="Connecter" method ="Get">
<table>
<tr><td>Enter your Username: </td>
<td><input type="text" name="userName"/></td></tr>
<tr><td>Enter your Password: </td>
<td><input type="password" name="password"/></td></tr>
<tr><td colspan="2" align="center"><input type="submit" value="login"> </td></tr>
</table>
</form>
</div>
</div>
</body>
</html>
这是我的Connecter类：
This is my Connecter class :
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;`
public class Connecter extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String n=request.getParameter("userName");
String p=request.getParameter("password");
if(LoginDao.validate(n, p)){
RequestDispatcher rd=request.getRequestDispatcher("welcom");
rd.forward(request,response);`
}
else {
out.print("Sorry username or password error");
RequestDispatcher rd=request.getRequestDispatcher("Sign up.jsp");
rd.include(request,response);
}
out.close();
}`
这是我的欢迎页面
import java.io.IOException;`
import java.io.PrintWriter;`
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;`
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class welcom extends HttpServlet {
public class WelcomeServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String n=request.getParameter("userName");
out.print("Welcome "+n);
out.close();
}
}
}
我的Dao页面
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
public class LoginDao {
public static boolean validate(String userName,String password){
boolean status=false;
try {
Class.forName("com.mysql.jdbc.Driver");
Connection con=DriverManager.getConnection
("jdbc:mysql://localhost:3306 /autolube","root","mehar");
PreparedStatement ps=con.prepareStatement
("select * from person where userName=?and password=?");
ps.setString(1,userName);
ps.setString(2,password);`ResultSet rs=ps.executeQuery();
status=rs.next();`}catch(Exception e){System.out.println(e);
}
return status;
}
}
推荐答案
你的servlet添加以下行。正如我所说的，我认为它的web.xml的一个问题。如果您使用的是servlet 3.0，您可以在web.xml中使用以下ammotation或map。
In your servlet add the below line. As I commented I think its a problem with web.xml. If you are using servlet 3.0 you can use the below ammotation or map in web.xml.
@WebServlet("/Connecter")
public class Connecter extends HttpServlet
