Java_Web之俱乐部会员信息管理系统

使用 Jsp实现俱乐部会员信息管理功能,orac1e11g作为后台数据库,该系统包括
查看俱乐部会员信息列表和修改俱乐部会员信息两人功能,具体耍求如下：

打开俱乐部会员信息列表页面,以列表方式显示所有俱乐部会员信息。

具体要求及推荐实现步骤：

第一步：创建数据表（memberisnfo）

create table memberisnfo(id number(10) primary key,--会员编号mname varchar2(30) not null, --会员姓名mgender varchar2(2) not null, --会员性别mage number(10) not null,--会员年龄maddress varchar2(100),--家庭位置memail varchar2(50) --电子邮件)--自增序列 CREATE SEQUENCE id_seq START WITH 1 INCREMENT BY 1 NOMAXVALUE  CACHE 10;  --插入数据insert into memberisnfo values (1,'黄鼠狼','男','36','江西生物科技职业学院','1210486771@qq.com');insert into memberisnfo values (id_seq.Nextval,'东东','男','20','江西生物科技职业学院','558899520@qq.com');insert into memberisnfo values (id_seq.Nextval,'薇薇','女','25','南昌理工学院','258258456@qq.com');insert into memberisnfo values (id_seq.Nextval,'花花','女','12','江西生物科技职业学院','2315429277@qq.com');select * from memberisnfo --查询数据

第二步：创建实体类

package entity;/* * 创建俱乐部会员系统实体参数 * * */public class Club_Name {     private String id;//创建id   private String mname;//创建名字实体   private String mgender;//创建日期实体   private String mage;//创建年龄实体   private String maddress;//创建地址实体   private String memail;//创建Emaile实体     public String getId() {    return id;  }  public void setId(String id) {    this.id = id;  }  public String getMname() {    return mname;  }  public void setMname(String mname) {    this.mname = mname;  }  public String getMgender() {    return mgender;  }  public void setMgender(String mgender) {    this.mgender = mgender;  }  public String getMage() {    return mage;  }  public void setMage(String mage) {    this.mage = mage;  }  public String getMaddress() {    return maddress;  }  public void setMaddress(String maddress) {    this.maddress = maddress;  }  public String getMemail() {    return memail;  }  public void setMemail(String memail) {    this.memail = memail;  }    }

创建数据库帮助类

package Dao_Base;  import java.sql.Connection;  import java.sql.DriverManager;  import java.sql.ResultSet;  import java.sql.SQLException;   import java.sql.Statement;  public class Base_Dao {      //数据库名和登入密码    String driver="oracle.jdbc.driver.OracleDriver";    String url="jdbc:oracle:thin:@localhost:1521:ORCL";    String user = "epet";    String pwd = "123456";        //建立数据库连接方法    public Connection getConnection(){      //加载驱动      try {        //第一步：加载驱动        Class.forName(driver);      } catch (ClassNotFoundException e) {        // TODO Auto-generated catch block        e.printStackTrace();      }            Connection con =null;              //获取连接对象      try {        con =DriverManager.getConnection(url,user,pwd);              //连接数据库      } catch (SQLException e) {        // TODO Auto-generated catch block        e.printStackTrace();              }         return con;    }            //======释放资源方法=======  public void ShiFang(ResultSet rs, Statement st,Connection con){        //如果结果集不为空，则释放成功 ，否则失败          try {            if(rs!=null){               rs.close();            }if(st!=null){               st.close();            }if(con!=null){             con.close();                          }              } catch (SQLException e) {          // TODO Auto-generated catch block          e.printStackTrace();              }          }          }

第三步：三层架构（业务逻辑层+数据访问层+实现层）

package Dao;import java.util.List;import entity.Club_Name;public interface Club_Name_Select {    //创建查询类所有人的位子的情况  public List<Club_Name> Culb();    //创建根据ID查询内容的方法  public List<Club_Name> Culb2(String id);    //根据id进行修改  public String Culd3(String id,String mname,String mgender,String mage,String maddress,String memail ); }

package Dao_Impl;import java.sql.Connection;import java.sql.PreparedStatement;import java.sql.ResultSet;import java.sql.SQLException;import java.util.ArrayList;import java.util.List;import entity.Club_Name;import Dao.Club_Name_Select;import Dao_Base.Base_Dao;public class Club_Name_Impl extends Base_Dao implements Club_Name_Select{    //创建数据库连接对象  Connection con=this.getConnection();    //创建写入sql语句的参数  PreparedStatement ps=null;    //创建结果集接收  ResultSet rs=null;    //创建sql语句  String sql="";  public List<Club_Name> Culb() {        //创建数据库查询    sql="select * from memberisnfo";        //创建实体类集合接收    List<Club_Name> list=new ArrayList<Club_Name>();        try {      //写入sql      ps=con.prepareStatement(sql);            //执行sql      rs=ps.executeQuery();            //循环输出并存入集合装入实体类      while(rs.next()){                //实例化实体类对象        Club_Name name=new Club_Name();                //开始存入        name.setId(rs.getString (1));        name.setMname(rs.getString(2));        name.setMgender(rs.getString(3));        name.setMage(rs.getString (4));        name.setMaddress(rs.getString(5));        name.setMemail(rs.getString(6));                //将查询的对象存入集合中去        list.add(name);      }    } catch (SQLException e) {      // TODO Auto-generated catch block      e.printStackTrace();    }    return list;  }  public List<Club_Name> Culb2(String id) {    //创建数据库查询    sql="select * from memberisnfo where id=?";        //创建实体类集合接收    List<Club_Name> list=new ArrayList<Club_Name>();        try {      //写入sql      ps=con.prepareStatement(sql);      ps.setString (1, id);            //执行sql      rs=ps.executeQuery();            //循环输出并存入集合装入实体类      while(rs.next()){                //实例化实体类对象        Club_Name name=new Club_Name();                //开始存入        name.setId(rs.getString (1));        name.setMname(rs.getString(2));        name.setMgender(rs.getString(3));        name.setMage(rs.getString (4));        name.setMaddress(rs.getString(5));        name.setMemail(rs.getString(6));                //将查询的对象存入集合中去        list.add(name);      }    } catch (SQLException e) {      // TODO Auto-generated catch block      e.printStackTrace();    }    return list;  }  public String Culd3(String id,String mname, String mgender, String mage,      String maddress, String memail) {        //创建数据库查询    sql="update memberisnfo set mname=?,mgender=?,mage=?,maddress=?,memail=? where id=?";        int q=0;    try {      //写入sql      ps=con.prepareStatement(sql);      ps.setString(1, mname);      ps.setString(2, mgender);      ps.setString (3, mage);      ps.setString(4, maddress);      ps.setString(5, memail);      ps.setString (6, id);            //执行sql      q=ps.executeUpdate();          } catch (SQLException e) {      // TODO Auto-generated catch block      e.printStackTrace();    }    if(q>0){            return "ok";    }else{            return "no";    }  }  }

package servlet;import java.io.IOException;import java.io.UnsupportedEncodingException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import Dao_Impl.Club_Name_Impl;public class Club_Name extends HttpServlet{    //创建post提交方法  public void doPost(HttpServletRequest request,HttpServletResponse response){            try {            //获取传过来的id值      String id=request.getParameter("id");      id=new String(id.getBytes("ISO-8859-1"),"utf-8");            //获取传过来的性别值      String sex=(String)request.getParameter("va");      sex=new String(sex.getBytes("ISO-8859-1"),"utf-8");            //获取名字的默认值      String name=request.getParameter("name");      name=new String(name.getBytes("ISO-8859-1"),"utf-8");            //获取年龄      String Mage=request.getParameter("year");      Mage=new String (Mage.getBytes("ISO-8859-1"),"utf-8");            //获取家庭住址      String Maddress=request.getParameter("location");      Maddress=new String(Maddress.getBytes("ISO-8859-1"),"utf-8");            //获取家庭住址      String Email=request.getParameter("email");      Email=new String(Email.getBytes("ISO-8859-1"),"utf-8");            //实例化更新对象      Club_Name_Impl impl=new Club_Name_Impl();            //调用更新的方法      String update=impl.Culd3(id, name, sex, Mage, Maddress, Email);            request.setAttribute("update", update);            //传送值到首页      request.getRequestDispatcher("index.jsp").forward(request, response);          } catch (UnsupportedEncodingException e) {      // TODO Auto-generated catch block      e.printStackTrace();    } catch (ServletException e) {      // TODO Auto-generated catch block      e.printStackTrace();    } catch (IOException e) {      // TODO Auto-generated catch block      e.printStackTrace();    }  }}
