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));

                //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

        int q=0;
