學生管理系統(Web)Sql Server+Eclipse

本文轉載自查看原文 2020-05-30 21:50 4587 Javaweb

項目源代碼：下載

一、應用名稱：STD學生管理系統（Javaweb）

二、使用工具：sql server數據庫，Eclipse軟件

三、實現的功能：多表的綜合運用，學生信息的增刪改查、條件查詢、模糊查詢、精確查詢等

四、步驟：

1、新建數據庫：student_message_mis

2、新建表：

①學生表：student（sno，sname,ssex,ssdept,sgrade）

屬性含義：（學號，姓名，性別，所在系，年級）

②宿舍表：home(sno,shome)

屬性含義：（學號，宿舍號）

create table student( sno int primary key, sname varchar(10) not null, ssex varchar(10), ssdept varchar(10), sgrade varchar(10)); create table home( sno int, shome varchar(10) not null, primary key(sno), foreign key(sno) references student(sno));

3、在eclipse新建web工程並導入連接sql server數據庫的jar包：sqljdbc4.jar

數據庫連接測試代碼

package com.test;

import java.sql.*;

public class Main {
    public static void main(String [] args)
    {
        String driverName="com.microsoft.sqlserver.jdbc.SQLServerDriver";
        String dbURL="jdbc:sqlserver://127.0.0.1:1433;DatabaseName=student";//test為你的數據庫名
        String userName="sa";//你的數據庫用戶名
        String userPwd="123456";//你的密碼
        try
        {
            Class.forName(driverName);
            System.out.println("加載驅動成功！");
        }catch(Exception e){
            e.printStackTrace();
            System.out.println("加載驅動失敗！");
        }
        try{
            Connection dbConn=DriverManager.getConnection(dbURL,userName,userPwd);
            System.out.println("連接數據庫成功！");
        }catch(Exception e)
        {
            e.printStackTrace();
            System.out.print("SQL Server連接失敗！");
        }        
    }
}

Main.java

4、新建index.jsp，實現加載學生所有信息，以及提供增加信息和查詢功能
