JavaWeb个人通讯录实现（JSP+JDBC）
JavaWeb实现通讯录
开发工具：idea2020.1 + navicat premium 15
开发技术：servlet + jsp + jdbc
源码地址：通信录源码：https://github.com/mogumogui/JAVAWEB-CONTACTLIST

通讯录功能演示：
- 首页（利用flexibile布局）
-
注册页面（利用js进行表单验证以及通过servlet对用户名进行是否存在校验）
若是表单信息不满足要求则表单提交失败
若注册用户名已存在则提示已存在 -
登陆页面（利用servlet进行用户名及密码验证）
若是账号不存在或者密码错误都将登陆失败并提示信息！ -
修改功能（通过servlet与jdbc对联系人数据库进行修改操作）
-
删除功能
-
查询功能（通讯servlet对通讯录进行条件查询）
可以通过姓名、电话号码、qq、电子邮箱进行查询！ -
管理员功能（可以修改删除用户信息）
各部分功能代码演示：
- main.jsp (js,css文件在上面给的github中)
<%@ page contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
个人通信录
<%@ include file="header.jsp" %>
个人通讯录
注册功能
通讯录用户注册
可以通过手机、邮箱、等方式注册。
修改功能
修改通讯录成员、修改用户
可以用户指定信息、并实时返回数据供使用者查看。
增加功能
增加通讯录成员
可以给登陆的用户为自己通讯录新增成员、并填写对应信息。
查询功能
查询通讯录成员
可以根据条件查询并获得通讯录成员信息。
管理员功能
管理用户
可以修改与删除用户的基本信息。
- 注册功能(register.jsp / RegisterServlet.java)
register.jsp

pageEncoding="UTF-8"%>
注册页面
<%@ include file="header.jsp" %>
通讯录用户注册
RegisterServlet.java

}
- 删除功能(DeleteFriendServlet.java)
package User.Servlet;
import User.Dao.FriendDao;
import java.io.IOException;

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**

// TODO Auto-generated method stub
response.setCharacterEncoding("utf-8"); // 设置编码格式
request.setCharacterEncoding("utf-8");
// 获取用户传过来的 friendid
int id = Integer.parseInt(request.getParameter("friendid"));
FriendDao friendDao = new FriendDao();
friendDao.detele(id);
response.getWriter().print("删除成功！");
request.getRequestDispatcher("index.jsp").forward(request,response);
