学生管理系统与MySql数据库的连接

连接数据库的源文件（重要）：
package com.tjl.jdbc;

import java.sql.DriverManager;

import java.sql.Statement;

import java.sql.Connection;

import java.sql.ResultSet;

public class JDBC {

public static void main(String[] args) {

//Drive loading
try {
Class.forName("com.mysql.jdbc.Driver");
System.out.println("Drive loading successful");
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/data?characterEncoding=utf8",
"root", "240055");

//Database connection
System.out.println("Database connection successful");
Statement statement  = conn.createStatement();
ResultSet result = statement.executeQuery("SELECT * FROM user");

while(result.next()) {
System.out.print(result.getInt("id") + "  ");
System.out.print(result.getString("uname") + "  ");
System.out.println(result.getString("upass"));
}

}catch (Exception e) {
e.printStackTrace();
System.out.println("Drive loading failed");
System.out.println("Database connection failed");
}
}

}
