Java_Web之俱樂部會員信息管理系統

使用 Jsp實現俱樂部會員信息管理功能,orac1e11g作為后台數據庫,該系統包括
查看俱樂部會員信息列表和修改俱樂部會員信息兩人功能,具體耍求如下：

打開俱樂部會員信息列表頁面,以列表方式顯示所有俱樂部會員信息。

具體要求及推薦實現步驟：

第一步：創建數據表（memberisnfo）

create table memberisnfo(
id number(10) primary key,--會員編號
mname varchar2(30) not null,  --會員姓名
mgender varchar2(2) not null, --會員性別
mage number(10) not null,--會員年齡
maddress varchar2(100),--家庭位置
memail varchar2(50)  --電子郵件
)
--自增序列
 CREATE SEQUENCE id_seq
  START WITH 1
  INCREMENT BY 1
  NOMAXVALUE
   CACHE 10;
   --插入數據
insert into memberisnfo values (1,'黃鼠狼','男','36','江西生物科技職業學院','[e-mail]');
insert into memberisnfo values (id_seq.Nextval,'東東','男','20','江西生物科技職業學院','[e-mail]');

insert into memberisnfo values (id_seq.Nextval,'薇薇','女','25','南昌理工學院','[e-mail]');

insert into memberisnfo values (id_seq.Nextval,'花花','女','12','江西生物科技職業學院','[e-mail]');
select * from memberisnfo  --查詢數據

第二步：創建實體類

package entity;

/*
 * 創建俱樂部會員系統實體參數
 * 
 * */
public class Club_Name {
    
     private String id;//創建id
     private String mname;//創建名字實體
     private String mgender;//創建日期實體
     private String mage;//創建年齡實體
     private String maddress;//創建地址實體
     private String memail;//創建Emaile實體     
    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;
    }
     

  

}

創建數據庫幫助類

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 {

    
        //數據庫名和登入密碼
        String driver="oracle.jdbc.driver.OracleDriver";
        String url="jdbc:oracle:thin:@localhost:1521:ORCL";
        String user = "epet";
        String pwd = "123456";
        
        //建立數據庫連接方法
        public Connection getConnection(){
            //加載驅動
            try {
                //第一步：加載驅動
                Class.forName(driver);
            } catch (ClassNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            
            Connection con =null;
              
              //獲取連接對象
            try {
                con =DriverManager.getConnection(url,user,pwd);
            
                //連接數據庫
            } catch (SQLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
                
            }
                 return con;
        }

        
        
        //======釋放資源方法=======

    public  void ShiFang(ResultSet rs, Statement st,Connection con){

               //如果結果集不為空，則釋放成功 ，否則失敗
                   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：三層架構（業務邏輯層+數據訪問層+實現層）

 

package Dao;

import java.util.List;

import entity.Club_Name;

public interface Club_Name_Select {
    
    //創建查詢類所有人的位子的情況
    public List<Club_Name> Culb();
    
    //創建根據ID查詢內容的方法
    public List<Club_Name> Culb2(String id);
    
    //根據id進行修改
    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{
    
    //創建數據庫連接對象
    Connection con=this.getConnection();
    
    //創建寫入sql語句的參數
    PreparedStatement ps=null;
    
    //創建結果集接收
    ResultSet rs=null;
    
    //創建sql語句
    String sql="";

    public List<Club_Name> Culb() {
        
        //創建數據庫查詢
        sql="select * from memberisnfo";
        
        //創建實體類集合接收
        List<Club_Name> list=new ArrayList<Club_Name>();
        
        try {
            //寫入sql
            ps=con.prepareStatement(sql);
            
            //執行sql
            rs=ps.executeQuery();
            
            //循環輸出並存入集合裝入實體類
            while(rs.next()){
                
                //實例化實體類對象
                Club_Name name=new Club_Name();
                
                //開始存入
                name.setId(rs.getString (1));
                name.setMname(rs.getString(2));

                name.setMage(rs.getString (4));
                name.setMaddress(rs.getString(5));
                name.setMemail(rs.getString(6));
                
                //將查詢的對象存入集合中去
                list.add(name);
            }
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return list;
    }

    public List<Club_Name> Culb2(String  id) {

            //循環輸出並存入集合裝入實體類
            while(rs.next()){
