二、项目大致的功能关系图
三、登陆层
1.login.jsp
介绍: 登陆界面,接收用户输入的账号密码
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>

</div>
</form>
</div>
</body>
</html>
2.LoginAction
介绍: 掉用dao层方法验证账号密码是否输入正确
package servlet;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import dao.UsersDaoImpl;
import entity.Users;
public class LoginAction extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = -947788533926255252L;
private static final UsersDaoImpl udi = new UsersDaoImpl();
@Override
protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
String username = req.getParameter("username");
String password = req.getParameter("password");
Users us = udi.queryUsersByUserName(username);
req.setAttribute("login", "yes");
if (us == null || !password.equals(us.getPassword())) {
req.setAttribute("login", "no");
req.setAttribute("msg", "用户名或密码不存在!");
req.getRequestDispatcher("/login.jsp").forward(req, resp);
} else {
req.getSession().setAttribute("name", username);
req.getSession().setAttribute("uid", us.getUsersId());
resp.sendRedirect("/jsp_day2/private/showMsg.jsp");
}
}
}
四、注册层

private static final UsersDaoImpl udi = new UsersDaoImpl();
@Override
protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
String username = req.getParameter("username");
String password = req.getParameter("password");
String affirm = req.getParameter("affirm");
String email = req.getParameter("email");
req.getSession().setAttribute("regist", "no");
if (username.equals("")) {
req.setAttribute("msg", "账号不能为空!");
req.getRequestDispatcher("/register.jsp").forward(req, resp);
} else if (password.equals("")) {
req.setAttribute("msg", "密码不能为空!");
req.getRequestDispatcher("/register.jsp").forward(req, resp);
} else if (email.equals("")) {

3. 删除信息
介绍: 当用户点击删除的超链接后,接收删除的msgid并调用dao层方法将其从数据库表中删除
package servlet;
import java.io.IOException;
import java.util.LinkedHashSet;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import dao.UsersDaoImpl;
public class DeleteMsgAction extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = -1566135640888064603L;
private static final UsersDaoImpl udi = new UsersDaoImpl();
@Override
protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
String[] msgid = req.getParameterValues("msgid");
if (msgid.length > 0) {
LinkedHashSet<Integer> msgIdSet = new LinkedHashSet<>();
for (String msgId : msgid) {
msgIdSet.add(Integer.parseInt(msgId));
}
udi.deleteAll(msgIdSet);
}
resp.sendRedirect("/jsp_day2/private/showMsg.jsp");
}
}
4.CloseSessionAction
介绍: 当用户点击退出超链接跳转的界面。主要是删除session信息,实现安全退出的功能
package servlet;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class CloseSessionAction extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = -4639818064873612493L;
@Override
protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
req.getSession().invalidate();
resp.sendRedirect("/jsp_day2/login.jsp");
}
}
七、过滤层
1.CaracterEncodingFilter
介绍: 指定编码格式的过滤器
package filter;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
public class CharacterEncodingFilter implements Filter {
private String encoding;
@Override
public void destroy() {
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
request.setCharacterEncoding(encoding);
response.setCharacterEncoding(encoding);
chain.doFilter(request, response);
}
@Override
public void init(FilterConfig filterConfig) throws ServletException {
encoding = filterConfig.getInitParameter("encoding");
}
}
2.CheckNomalCommingFilter
介绍: 检查是否为正常请求,并通过不同的非法请求将其重定向到对应的界面
package filter;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
public class CheckNomalCommingFilter implements Filter {
@Override
public void destroy() {
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
HttpSession session = req.getSession();
HttpServletResponse resp = (HttpServletResponse) response;
String un = (String) session.getAttribute("name");
session.getAttribute("regist");
String path = req.getServletPath();
String unRegist = req.getParameter("username");
String recName = req.getParameter("recname");
String unLogin = unRegist;
String replyId = req.getParameter("msgid");
String mainEmail = req.getParameter("email");
String mainSuccess = (String) session.getAttribute("mainsuccess");
// 先判断是不是注册请求,如果是就进行筛选
if (path.contains("/regist")) {
if ((path.equals("/check/regist") && unRegist == null) || (path.contains("/registsuccess.jsp")
&& (session.getAttribute("regist") == null || session.getAttribute("regist").equals("no")))) {
resp.sendRedirect("/jsp_day2/register.jsp");
} else {
chain.doFilter(request, response);
}
// 如果不是注册请求,进行第二轮筛选
} else if (un == null && unLogin == null) {
resp.sendRedirect("/jsp_day2/login.jsp");
} else if (path.contains("/check/send") && recName == null) {
resp.sendRedirect("/jsp_day2/private/newMsg.jsp");
} else if (path.contains("replyMsg") && (replyId==null || replyId.equals(""))) {
resp.sendRedirect("/jsp_day2/private/showMsg.jsp");
} else if ((path.contains("/check/main") && mainEmail == null)
|| (path.contains("/mainsuccess") && mainSuccess == null)) {
resp.sendRedirect("/jsp_day2/private/showMsg.jsp");
} else {
chain.doFilter(request, response);
}
}
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
}
八、dao层
1.UsersDao接口
介绍: 声明了一下需要用到的方法
package dao;
import java.util.LinkedHashSet;
import java.util.List;
import entity.Message;
import entity.Users;
public interface UsersDao {
// // 通过用户名查询密码和id
// public String[] queryPasswordByUserName(String username);
// 根据用户名查询该用户的全部信息
public Users queryUsersByUserName(String username);
// 判断用户名是否存在
public boolean ifExistToUserName(String username);
// 修改用户信息
public void updateUsers(Users u);
// 往users表中添加一条用户信息
public boolean insertUsers(Users u);
// 往message表中添加一条信息
public boolean insertMessage(Message m);
// 根据收件人编号,返回所有跟该用户有关的信息
public List<Message> selectAllWithThis(Integer receiverId);
// 返回除自身外的所有用户姓名
public List<String> selectAll(String username);
// 通过id查询用户姓名
public String selectOne(Integer usersid);
// 获取下一个用户表的序列值
public int getUsersSeq();
// 获取下一个信息表的序列值
public int getMessageSeq();
// 通过id批量删除短信
public void deleteAll(LinkedHashSet<Integer> messageIdSet);
// 修改阅读标记
public void updateFlag(Integer flag,Integer msgid);
// 根据msgid查看具体内容
public Message selectMessageByMsgId(Integer msgid);
// 获取当前时间
public String getTime();
}
