簡單地JDBC小實例

package com.javaJDBCTest;

import java.sql.DriverManager;
import java.sql.ResultSet;

import com.mysql.jdbc.Connection;
import com.mysql.jdbc.Statement;

public class JDBCTestDemo1 {

	public static void main(String args[]) throws Exception
	{
		//加載驅動類
		Class.forName("com.mysql.jdbc.Driver");
		
		//通過DriverManager獲取數據庫連接
		String url = "jdbc:mysql://127.0.0.1/TestDB";
		String user = "root";
		String password = "ddddd";
		Connection connection = (Connection) DriverManager.getConnection(url, user, password);
		
		//通過connection對象獲取Statement對象,執行SQL語句
		Statement statement = (Statement)connection.createStatement();
		ResultSet resultSet = statement.executeQuery("select * from customers");
		
		//操作ResultSet
		while(resultSet.next())
		{
			System.out.println(resultSet.getString("cust_name"));
		}
		
		//關閉數據庫連接
		resultSet.close();
		statement.close();
		connection.close();
	}
}

這是MySQL表

連接成功,獲取表數據:
