不使用mybatis，直接用jdbc连接数据库 最后更新时间：2024年12月26日 #### 思路 1. 构建项目 2. 导入jdbc驱动类。 3. 创建连接 4. 查询数据 #### 实例： ```java package org.example; import org.gjt.mm.mysql.Driver; import java.sql.Connection; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement; import java.util.Properties; public class Main { public static void main(String[] args) throws SQLException { Driver driver = new Driver(); Properties properties = new Properties(); properties.setProperty("user","root"); properties.setProperty("password","123456"); Connection connect = driver.connect("jdbc:mysql://localhost:3306/kettle?createDatabaseIfNotExist=true&useSSL=false", properties); Statement stmt = connect.createStatement(); ResultSet data = stmt.executeQuery("select 100 as va;"); while (data.next()){ System.out.println(data.getString("va")); } connect.close(); } } ```
