通过Java连接SQL Server数据库的超详细操作流程

win + r输入cmd,命令窗口输入java --version

package com.alon.sqlutils;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class JDBCTest {
	public static void main(String[] args)  {
		String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
		String dburl = "jdbc:sqlserver://localhost:1433;DatabaseName = student;
		String userName = "sa";//填写自己的数据库名称
		String userPwd = "root";//数据库对应密码
		try {
			Class.forName(driverName);
			System.out.println("连接成功!!!");
			
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
			System.out.println("驱动加载失败");
		}
	
		try {
			Connection dbcon = DriverManager.getConnection(dburl,userName,userPwd);
			System.out.println("数据库连接成功！");
		} catch (SQLException e) {
			e.printStackTrace();
			System.out.println("连接失败");
			
		}
	}
}
