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'); 
UNLOCK TABLES; 
 
DROP TABLE IF EXISTS `student`; 
CREATE TABLE `student` ( 
 `id` int(11) NOT NULL AUTO_INCREMENT,`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','zhangsan@163.com','13888888888','男'),(19,'李四','002','理学院','上海','70','lisi@sina.com','13812341234',(20,'王五','003','外国语学院','北京','88','wangwu@126.com','13698765432','女'); 
UNLOCK TABLES;

3、model--管理员、学生

package com.student.model; 
 
/**

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) {

  } 
 
}

/**

 */ 
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

  } 
 
  public String getSno() { 
    return sno; 
  } 
 
  public void setSno(String sno) { 
    this.sno = sno; 
  } 
 
  public String getName() { 
    return name; 
  }

  } 
 
  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）

    } 
    try {

      result = ps.executeUpdate(); 
    } catch (SQLException e) {

    return result; 
  } 
 
  public int executeUpdate(String sql,Object[] obj) {

      for (int i = 0; i < obj.length; i++) {

      } 
      result = ps.executeUpdate(); 
      close(); 
    } catch (SQLException e) {

    } 
    return result; 
  } 
 
  public ResultSet executeQuery(String sql) { 
    if (getConn() == null) { 
      return null; 
    } 
    try {

      } 
      rs = ps.executeQuery();

      } 
    } catch (SQLException e) { 
      e.printStackTrace();

  } 
}

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。
