首先是 login.html
后台登陆系统
管理员登陆
然后是LoginServlet
package com.caizhen.Servlet;
import java.io.IOException;
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.caizhen.pojo.User;
/**
* Servlet implementation class login
*/
@WebServlet("/login")
public class LoginServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public LoginServlet() {
super();
// TODO Auto-generated constructor stub
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String name=request.getParameter("name");
String password=request.getParameter("password");
if("caizhen".equals(name)&&"123456".equals(password)) {
User user=new User();
user.setName(name);
user.setPassword(password);
request.getSession().setAttribute("user", user);
response.sendRedirect("success.html");
}else {
response.sendRedirect("error.html");
}
}
/**
* @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);
}
}
然后是登陆成功的界面
success.html
Insert title here
恭喜成功登陆 退出
然后是登出操作
package com.caizhen.Servlet;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet("/LogoutServlet")
public class LogoutServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public LogoutServlet() {
super();
// TODO Auto-generated constructor stub
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.getSession().removeAttribute("user");
response.sendRedirect("login.html");
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doGet(request, response);
}
}
然后是web.xml
index.html
index.htm
index.jsp
default.html
default.htm
default.jsp
LoginServlet
com.caizhen.Servlet.LoginServlet
LoginServlet
/webapp/LoginServlet
LogoutServlet

User.java
package com.caizhen.pojo;
public class User {
private String password;
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
