项目关键代码

连接数据库的类代码：

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

public class DBUtil {

private static final String URL = "jdbc:mysql://localhost:3306/student";

private static final String NAME = "root";

private static final String PASSWORD = "123456";

public static void exec(String str) throws ClassNotFoundException, SQLException {

// 1.加载驱动程序

Class.forName("com.mysql.jdbc.Driver");

// 2.获得数据库的连接

Connection conn = DriverManager.getConnection(URL, NAME, PASSWORD);

// 3.通过数据库的连接操作数据库，实现增删改查

Statement stmt = conn.createStatement();

stmt.execute(str);

stmt.close();

conn.close();

}

static ResultSet query(String sql) throws SQLException, ClassNotFoundException {

Class.forName("com.mysql.jdbc.Driver");

// 1.获得数据库的连接

Connection conn = DriverManager.getConnection(URL, NAME, PASSWORD);

// 2.通过数据库的连接操作数据库，实现增删改查

Statement stmt = conn.createStatement();

try {

return stmt.executeQuery(sql);

} catch (SQLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return null;

}

}

增加方法的函数：

package database;

import database.DBUtil;

import java.sql.*;

public class ADD{

public static void add(String number,String name,String gender,String birthdate,String politics,String address,String telephone,String dormitory){

String str = "insert into students(number,name,gender,birthdate,politics,address,telephone,dormitory)"

+ " values("+"'"+number+"'"+"," + "'"+name+"'"+"," +"'"+ gender+"'"+"," +"'"+ birthdate+"'"+"," +"'"+ politics+"'" +","+"'"+ address+"'"+"," +"'"+telephone+"'"+"," +"'"+ dormitory+"'"+")";

try {

DBUtil.exec(str);

} catch (ClassNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (SQLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

更改的函数：

public class CHANGE {

public static void change(String number, String name, String gender, String birthdate, String politics,

String address, String telephone, String dormitory) {

String str = "update students set number='" + number + "',gender='" + gender + "'," + "birthdate='" + birthdate

+ "'," + "politics='" + politics + "'," + "address='" + address + "'," + "telephone='" + telephone

+ "'," + "dormitory='" + dormitory + "' " + "where name=" + "'" + name + "';";

try {

System.out.println(str);

DBUtil.exec(str);

} catch (ClassNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (SQLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

删除的函数：

public class DELETE {

public static String[][] delete(String name){

String str ="delete from students where name="+"'"+name+"'"+";";

String[][] strs = new String[100][8];

try{

DBUtil.exec(str);

}catch (ClassNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (SQLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return strs;

}

}

搜索的函数：

public class SEARCH {

public static String[][] serach(String name){

String str = "select * from students where name="+"'"+name+"'"+";";

String[][] strs = new String[100][8];

try{

ResultSet resultSet = DBUtil.query(str);

int cnt = 0;

while (resultSet.next()) {

for (int i = 0; i < 8; i++) {

strs[cnt][i] = resultSet.getString(i + 1);

}

cnt++;

}

}catch (ClassNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (SQLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return strs;

}

}

尚待改进或者新的想法

尚待改进的：

①由于时间太少，所以界面做的很粗糙and 丑。

②可以在新增加一个注册管理员的功能，注册管理员然后用注册的账号登陆信息管理系统。

③在更改数据库信息的时候可以只更新部分信息，不更新全部的信息，然而在设计的系统里面只能更改全部的信息。

④最后打包成jar包可以在包装成exe。
