学生信息管理系统--（Java+MySQL实现）

版权声明：本文为博主原创文章，未经博主允许不得转载。 https://blog.csdn.net/ZhuangM_888/article/details/50476423

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;
	}

}

/**

 * 修改历史：

 * 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

/**

public abstract class BaseDAO {
	protected final DBUtil db = DBUtil.getDBUtil();
	protected ResultSet rs;
	private static BaseDAO baseDAO;

	public BaseDAO() {

	}

	public static synchronized BaseDAO getAbilityDAO(DAO dao) {

			}
			break;
		case StudentDAO:
			if (baseDAO == null || baseDAO.getClass() != StudentDAO.class) {
				baseDAO = StudentDAO.getInstance();
			}
			break;
		default:
			break;
		}
		return baseDAO;
	}

	protected void destroy() {
		try {
			if (rs != null) {
				rs.close();
			}
		} catch (SQLException se) {
			se.printStackTrace();
		} finally {

		}
	}
}

AdminDAO.java

/**

public class AdminDAO extends BaseDAO {

	private static AdminDAO ad = null;

	public static synchronized AdminDAO getInstance() {

	}

	public boolean queryForLogin(String username, String password) {

		}

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。
