Java+MySQL实现学生信息管理系统源码

基于Java swing+MySQL实现学生信息管理系统：主要实现JDBC对学生信息进行增删改查，应付一般课设足矣，分享给大家。（由于篇幅原因，代码未全部列出，如有需要留下邮箱）

鉴于太多同学要源码，实在发不过来，上传到github上 https://github.com/ZhuangM/student.git

1、 开发环境：jdk7+MySQL5+win7

代码结构：model-dao-view

2、 数据库设计--建库建表语句：

CREATE DATABASE student;


DROP TABLE IF EXISTS `admin`;
CREATE TABLE `admin` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `name` varchar(20) NOT NULL,
 `username` varchar(20) NOT NULL,
 `password` varchar(20) NOT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

LOCK TABLES `admin` WRITE;
INSERT INTO `admin` VALUES (1,'admin','admin','admin');
UNLOCK TABLES;

DROP TABLE IF EXISTS `student`;
CREATE TABLE `student` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `name` varchar(20) NOT NULL,
 `sno` varchar(20) NOT NULL,
 `department` varchar(20) NOT NULL,
 `hometown` varchar(20) NOT NULL,
 `mark` varchar(20) NOT NULL,
 `email` varchar(20) NOT NULL,
 `tel` varchar(20) NOT NULL,
 `sex` varchar(20) NOT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=22 DEFAULT CHARSET=utf8;

LOCK TABLES `student` WRITE;
INSERT INTO `student` VALUES (18,'张三','001','信息科学技术学院','辽宁','80','[email protected]','13888888888','男'),(19,'李四','002','理学院','上海','70','[email protected]','13812341234','男'),(20,'王五','003','外国语学院','北京','88','[email protected]','13698765432','女');
UNLOCK TABLES;

3、model--管理员、学生

/**

 */
package com.student.model;

/**
 * 模块说明：admin
 *
 */
public class Admin {
 private int id;
 private String name;
 private String username;
 private String password;

 public String getName() {
  return name;
 }

 public void setName(String name) {
  this.name = name;
 }

 public int getId() {
  return id;
 }

 public void setId(int id) {
  this.id = id;
 }

 public String getUsername() {
  return username;
 }

 public void setUsername(String username) {
  this.username = username;
 }

 public String getPassword() {
  return password;
 }

 public void setPassword(String password) {
  this.password = password;
 }

}

/**

 * 创建时间： 2016年1月6日-上午9:42:36
 */
package com.student.model;

/**
 * 模块说明： 学生
 *
 */
public class Student {
 private int id;
 private String sno;// 学号
 private String name;
 private String sex;
 private String department;// 院系
 private String homeTown;// 籍贯
 private String mark;// 学分
 private String email;
 private String tel;// 联系方式

 public int getId() {
  return id;
 }

 public void setId(int id) {
  this.id = id;
 }

 public String getSno() {
  return sno;
 }

 public void setSno(String sno) {
  this.sno = sno;
 }

 public String getName() {
  return name;
 }

 public void setName(String name) {
  this.name = name;
 }

 public String getSex() {
  return sex;
 }

 public void setSex(String sex) {
  this.sex = sex;
 }

 public String getDepartment() {
  return department;
 }

 public void setDepartment(String department) {
  this.department = department;
 }

 public String getHomeTown() {
  return homeTown;
 }

 public void setHomeTown(String homeTown) {
  this.homeTown = homeTown;
 }

 public String getMark() {
  return mark;
 }

 public void setMark(String mark) {
  this.mark = mark;
 }

 public String getEmail() {
  return email;
 }

 public void setEmail(String email) {
  this.email = email;
 }

 public String getTel() {
  return tel;
 }

 public void setTel(String tel) {
  this.tel = tel;
 }

}

4、 工具类DBUtil（对jdbc进行封装）

/**
 * 项目名：student
 * 修改历史：
 * 作者： MZ
 * 创建时间： 2016年1月6日-上午9:43:21
 */
package com.student.util;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

import com.student.AppConstants;

/**
 * 模块说明：数据库工具类
 *
 */
public class DBUtil {
 private static DBUtil db;

 private Connection conn;
 private PreparedStatement ps;
 private ResultSet rs;

 private DBUtil() {

 }

 public static DBUtil getDBUtil() {
  if (db == null) {
   db = new DBUtil();
  }
  return db;
 }

 public int executeUpdate(String sql) {
  int result = -1;
  if (getConn() == null) {
   return result;
  }
  try {
   ps = conn.prepareStatement(sql);
   result = ps.executeUpdate();
  } catch (SQLException e) {
   e.printStackTrace();
  }
  return result;
 }

 public int executeUpdate(String sql, Object[] obj) {
  int result = -1;
  if (getConn() == null) {
   return result;
  }
  try {
   ps = conn.prepareStatement(sql);
   for (int i = 0; i < obj.length; i++) {
    ps.setObject(i + 1, obj[i]);
   }
   result = ps.executeUpdate();
   close();
  } catch (SQLException e) {
   e.printStackTrace();
  }
  return result;
 }

 public ResultSet executeQuery(String sql) {
  if (getConn() == null) {
   return null;
  }
  try {
   ps = conn.prepareStatement(sql);
   rs = ps.executeQuery();
  } catch (SQLException e) {
   e.printStackTrace();
  }
  return rs;
 }

 public ResultSet executeQuery(String sql, Object[] obj) {
  if (getConn() == null) {
   return null;
  }
  try {
   ps = conn.prepareStatement(sql);
   for (int i = 0; i < obj.length; i++) {
    ps.setObject(i + 1, obj[i]);
   }
   rs = ps.executeQuery();
  } catch (SQLException e) {
   e.printStackTrace();
  }

  return rs;
 }

 private Connection getConn() {
  try {
   if (conn == null || conn.isClosed()) {
    Class.forName(AppConstants.JDBC_DRIVER);
    conn = DriverManager.getConnection(AppConstants.JDBC_URL, AppConstants.JDBC_USERNAME,
      AppConstants.JDBC_PASSWORD);
   }
  } catch (ClassNotFoundException e) {
   System.out.println("jdbc driver is not found.");
   e.printStackTrace();
  } catch (SQLException e) {
   e.printStackTrace();
  }
  return conn;
 }

 public void close() {
  try {
   if (rs != null) {
    rs.close();
   }
   if (ps != null) {
    ps.close();
   }
   if (conn != null) {
    conn.close();
   }
  } catch (SQLException e) {
   e.printStackTrace();
  }
 }
}

5、 dao：主要调用DBUtil操作相应的model--增删改查

BaseDAO.java

   }
   break;

    baseDAO = StudentDAO.getInstance();
   }
   break;
  default:
   break;
  }
  return baseDAO;
 }

 protected void destroy() {
  try {
   if (rs != null) {

6、 view：与用户交互的界面（包括LoginView.java、MainView.java、AddView.java、DeleteView.java、UpdateView.java），主要使用DAO提供的接口，由于篇幅原因，仅列出MainView即首页。
